Sonic Forces

Sonic Forces (ソニックフォース) is a platform video game in the Sonic the Hedgehog series developed by Sonic Team and published by Sega. It was released on 7 November 2017 for PC, Nintendo Switch, PlayStation 4 and Xbox One. Sonic Forces follows Sonic the Hedgehog as he joins a resistance force against Dr. Eggman, who has taken over the world with the help of his army, henchmen and a mysterious new villain known as Infinite. The storyline of the game also ties with Sonic Mania.

The game marks the return of the collaboration between both Classic Sonic and Modern Sonic, along with their associated gameplay styles, since the twentieth anniversary game Sonic Generations (although it is not a sequel to any previous games ). In addition, Sonic Forces also introduces a third gameplay mode featuring the "Avatar", the player's own created character. The game serves, along with Sonic Mania, as a “continuation” of Sonic’s 25th anniversary.

History
Sonic Forces has been in development since 2013, around the release of Sonic Lost World. The title was first mentioned at the Tokyo Joypolis Sonic 25th party on 25 June 2016 under the name "Project Sonic 2017". The game was developed by Sonic Team, the same team that had previously developed Sonic Colors and Sonic Generations, and was headed by Sonic series veteran Takashi Iizuka.

The idea for Sonic Forces was to bring back a modern 3D Sonic made by Sonic Team themselves, who had not engaged in such a project for a while. The goal was to give players the experience of a classic 3D Sonic game while also offering as much content as possible by including old fan-favorite characters and 2D gameplay experiences. Also, because Sonic Team had gotten a lot of feedback from people who wanted to create their own characters in the Sonic universe, they decided to implement the Avatar system so fans could both create their own original character and go on adventures with Sonic through them.

The first half of the game was produced by Iizuka, with Shun Nakamura stepping in when the game became more defined. Although the direction of the game was intended to be “Vs. Eggman”, the addition of colliding armies was added to the mix to make the game stand out. To make the game' story more serious, it was written so that 99% of the world had been conquered by Eggman. According to Nakamura, the team tried to make a detour from Sonic's normal streak of victories by adding an element of despair, namely by having Sonic rescue a world stuck in despair from Eggman's tyranny. Furthermore, the team sought to express character development through the Avatar, something which is difficult for Sonic, to add more fitting depth to the story. Also, according to Iizuka, the All-star cast in the game itself came as a result of the game's premise rather than the other way around.

The subtitle "Forces" was chosen because the word incorporates the themes of “power” and “army”. These words embody the main theme of the game, with two strong forces (Sonic and co. versus Eggman) facing off against one another in the game.

The decision to exclude the classic mechanic that let the player recover dropped Rings is a result of Sonic Mania: after having a game with the classic mechanics, Sonic Team wanted to make something new that fit the modern style of Sonic Forces and provided a balanced aspect to the game difficulty that fans of both Modern and Classic gameplay would enjoy. In terms of story, Sonic Team wanted to put Infinite in focus with a strong secondary main villain cast constantly interacting with him, which is something that has not been seen in the series before and would give the fan-favorite characters enough screentime. Also, the darker story approach for the game came as a product of the cast: when Sonic Team wanted the villains of the game to stand out as more threatening, dramatic and powerful, they needed a setting to emphasize the villainous activities going on and how Eggman is taking over the world, which led to the development of the darker world Sonic Forces takes place in.

As the Nintendo Switch had not yet been revealed, the development team could not properly complete that version of Sonic Forces. After it had been revealed, they had still managed to create an algorithm so that the game could manage to run at 720p on the Switch version.

Promotion
The game was announced at Sega's 25th anniversary of the series at San Diego Comic-Con on 22 July 2016, where it was announced alongside Sonic Mania. The presence of Classic and Modern Sonic led some journalists to believe it was a sequel to Sonic Generations, but Iizuka confirmed that it was not a sequel, but a new, stand-alone title. The game will be released for Nintendo Switch, PC, PlayStation 4 and Xbox One in late 2017.

During the Sonic live stream that was held in Japan due to the release of Sonic Boom: Fire & Ice, it was revealed that there will be a new character introduced in Sonic Forces, along with a new component of gameplay besides the regular 2D and 3D gameplay.

SXSW 2017 announced they would be hosting a second Sonic panel for this year’s event, set to reveal news about the upcoming Sonic Mania and Sonic Forces. The latest Nintendo Dream Magazine from Japan also revealed new information about Sonic Forces. The blurb stated that Dr. Eggman will be the main villain, that there will be no multiplayer features, and that the genre for the game is "adventure". Soon after, it was unveiled that the game will be an evolution of Sonic Colors and Sonic Generations and features a new game engine developed for this title called "Hedgehog Engine 2". An interview with Takashi Iizuka by Famitsu later revealed that "Boom Sonic" would not appear in the game and that the game's third character (who will be revealed at E3 2017) would be an "unexpected character" that plays a vital role in the story and "embodies the overall features of the game". On 16 May 2017 (a month earlier than planned), this third character turned out to be a character that the player can customize to their liking. At E3 2017, on 13 June 2017, Shadow the Hedgehog, Metal Sonic, Zavok, and Chaos were confirmed to return to Sonic Forces as Dr. Eggman's henchmen under the leadership of a new and mysterious villain called Infinite. Soon after, Chao were stated not to be featured in the game, though they do make cameos as decorative gear for the Avatar.

At Gamescom 2017, Sonic Forces appeared with new demos that featured a new type of level for the game called "Tag Team Stages" where Modern Sonic and the player's Avatar work together in collaborative gameplay. On 31 August 2017, it was announced on the official twitter feed of Sonic that the game will arrive on 7 November 2017 on all platforms. A physical bonus edition of the game with extra features was also announced to be available for pre-order for consoles.

It was later announced that Sonic Forces would be showcased on Tokyo Game Show 2017, where limited game-related merchandise would be handed out to the attendees. At said event, Takashi Iizuka revealed that the storyline of Sonic Forces ties into Sonic Mania. It was also announced at TGS that Sonic Forces would have a cross-promotion with Hooters Japan and Hatsune Miku: Project DIVA Future Tone DX. Also, on 19 September 2017, a DLC named "Episode Shadow" featuring Shadow as a playable character was announced.

A demo for Sonic Forces was released on 25 October 2017 in Japan for PlayStation 4 and the Nintendo Switch. Three stages were made available: Green Hill Zone with Modern Sonic, Space Port with the Avatar and the Egg Dragoon boss fight as Classic Sonic. Players were only given sixty seconds play-time on each stage.

Plot
Sonic Forces has the primary themes of "forces", "power", and "teamwork". Making yet another gab for global domination, Dr. Eggman launches a large scale offensive on an urban center with his Death Egg Robot sentinels and Egg Pawns. As things gets desperate for the survivors and all hope seems lost, Sonic the Hedgehog appears and makes short work of the remaining forces. However, Dr. Eggman has a surprise up his sleeve.

Sonic soon finds himself face to face with a troop of much tougher enemies which consist of none other than Shadow, Metal Sonic, Zavok, and Chaos, who are now serving as Eggman's henchmen once more and are ready to create more next-level panic and disorder. Among them is also a newcomer: an enigmatic and powerful being named Infinite, who has provided Eggman with a new power and now serves as his right-hand man. Wielding a mysterious power, Infinite proves too much for Sonic, who is defeated and captured by the unknown assailant. After that, Sonic disappears into thin air, his present status unknown, with his best friend Tails losing contact with him.

With Infinite's power and no Sonic to oppose him, Dr. Eggman manages to conquer 99% of the planet in a matter of a few short months, resulting in his army controlling that much of the world. Acting on Eggman's behalf, Shadow, Metal Sonic, Chaos and Zavok easily conquer one territory after another. Meanwhile, Infinite has become the leader of Eggman's entire army. With Eggman out to crush the remaining opposition, multiple forces are now embroiled in conflict for the control of the planet.

Sonic’s disappearance was shocking news to everyone. Sonic’s friends, who managed to escape Eggman’s invasion, decide to fight back by forming the rag-tag “Resistance” army, with Knuckles the Echidna as the commander. Joining the Resistance is an active newcomer from a district of survivors that got attacked by Dr. Eggman’s army. This rookie has decided to answer the call and fight to get the world back. As the Eggman Empire's armies lay waste to entire cities, Sonic returns and joins up with the Resistance. Classic Sonic, Sonic's counterpart from another dimension, also appears, having been brought to Sonic's dimension by the same power Eggman used to conquer the world. Now, with the aid of his friends, the resistance rookie, and Classic Sonic, Sonic embarks on a mission to save the world and end the evil reign of the diabolical doctor and his forces. However, time grows short for Sonic, as the Resistance only has three days before Eggman unleashes a plan that will eradicate all his foes.

Gameplay
Sonic Forces includes three playable characters and a fourth optional character via DLC. Akin to Sonic Adventure 2, the story will be told from the perspective of each of the characters throughout the game, and when it all is put together it will tell the overarching story. The first two of these characters include Classic Sonic (Sonic's original design from the Sega Mega Drive Sonic games) and Modern Sonic (Sonic's revised form in Sonic Adventure and after). Other main characters will make non-playable appearances, offering support and advice to the player via radio communication.

The game's third playable character is a new character, referred to as the Avatar, whom players can modify to their liking, which is a first for the series. The Avatar is created from the base of seven animal species, and possess several attributes that can be customized. However attributes like species, gender, head shape, eye shape and voice can only be set once. While playing through the game, one can unlock hundreds of accessories and costuming options for the Avatar. Depending on what animal species the Avatar is, they will gain a unique ability to aid in gameplay:


 * Bear: Blows away enemies with a Homing Attack
 * Bird: Flies high with Double Jump abilities
 * Cat: Keeps one Ring after being hit
 * Dog: Restarts with five Rings after the player dies
 * Hedgehog: [original] Collected Rings when getting damaged
 * [day-one patch] Dropped rings remain longer after taking damage
 * Rabbit: Has longer invincible time after receiving damage
 * Wolf: Automatically draws in Rings when near them

The overall gameplay is relatively unchanged from previous Sonic entries; players run at high speeds through levels filled with gimmicks, enemy robots, and other hazards on the way to the goal. If the player takes more than 60 minutes to complete a stage, they will receive a Time Over and be returned to the stage select screen (also called the "World Map"). Scattered around levels are Rings: Rings protect players when they take damage, though they will lose their Rings upon being hit. Sonic Forces has two difficulties that affect the Ring cap. "Normal" mode only allows players to collect up to 100 Rings. Getting hit by enemies will decrease the Ring count by twenty each time. "Hard" mode on the other hand allows players to collect up to 999 Rings, but getting hit will make them lose all their Rings. Taking damage without any Rings will cost the player a life. A character will also lose a life if they drown or fall into a bottomless pit. Losing a life makes the player start from the last Star Post they passed in an stage or from the beginning of the stage if they have not passed any Star Posts. However, Nakamura has stated that there are no Game Overs. Wisps, which give players temporary special powers, from earlier games also return. The game also incorporates a point system in the form of "Stage Scores" for each stage, which can be increased by collecting Rings and item, attacking enemies, and destroying obstacles.

The game features four different gameplay styles. Two of these include those of Modern Sonic and Classic Sonic respectively as seen in Sonic Generations, with both of them having different sets of abilities. Some stages involve simply reaching the goal, while others will require a stage to be beaten under a time limit. Modern Sonic's stages are based around three-dimensional movement like that of Sonic Unleashed and Sonic Colors, with Modern Sonic having his standard Spin Jump, Double Jump, Jump Dash, Homing Attack, Quick Step and Stomp maneuvers, along with a reworked Air Boost and Boost. Classic Sonic's stages meanwhile, focuses on 2.5D side-scrolling stages reminiscent of the Sega Mega Drive-era of games, except this time they will feature a “twist”. Classic Sonic will also have maneuvers like the signature Spin Dash and the Drop Dash from Sonic Mania. There is also a Rank system installed in the game that is given at each end of the level based on the player's performance in said level.

The third gameplay style features the Avatar. Its style is similar to Modern Sonic's, but utilizes a grappling hook as a means of platforming. The Avatar also makes use of new unique gadgets called Wispons for both attacking enemies and traversal. Depending on the Wispon equipped, Avatars can harness Color Powers in new ways by collecting a corresponding Wisp within each stage; e.g. if the Avatar is equipped with the Burst Wispon, they can activate Red Burst abilities. Before a level, the player can choose different Wispons to customize how the Avatar controls, thereby allowing access to different parts of the levels. Like accessories, players can unlock new Wispons as they progress. Sonic Forces also has network synchronization, allowing players from around the world to "rent" other players' Avatars and their equipped Wispon. These "Rental Avatars" can be chosen on the World Map and can be freely switched out with the player's own Avatar during gameplay.

The fourth gameplay features a tag team mechanic (akin to that in Sonic Heroes) that involves Modern Sonic and the Avatar. The player will wield both characters to navigate through the level, with the leader automatically switching to Sonic when boosting and the Avatar when using the Wispon. Also included is a new move called the "Double Boost", which is a faster version of the Boost that is triggered when the player engages in an automatic Real-Time Interaction.

Episode Shadow
Episode Shadow is a free add-on pack for anyone who owns Sonic Forces. It focuses on Shadow the Hedgehog, Rouge the Bat and E-123 Omega, and serves as a prequel to the main storyline of Sonic Forces. It launched alongside the game with Sonic Forces Digital Bonus Edition and also in the normal packs of the game.

"Episode Shadow" explores Shadow's allegiance, the fate of Team Dark, and the origin of Infinite. The player assumes control over Shadow, who handles similarly to Modern Sonic. The pack also adds thirteen extra levels to the game; three are original, while ten are redesigned versions of Modern Sonic stages.

According to Shun Nakamura, Sonic Team created "Episode Shadow" to help the game appeal to fans of older games such as Sonic Adventure. Upon its announcement, several gaming journalists noted that "Episode Shadow" was the first time Shadow was a playable character in a mainline Sonic game for several years, and Game Informer wrote that it was much more difficult than the main game.

Music
The game's soundtrack is being composed by Sonic series sound director, Tomoya Ohtani, and composer, Naofumi Hataya. Kenichi Tokoi also contributed with a remix of the US version of Stardust Speedway for Metal Sonic's boss battle. The game's theme song, "Fist Bump", features lyrics written and performed by Douglas Robb, vocalist of the American rock band Hoobastank. Singers Jon Underdown and Nana Hatori will contribute to the soundtrack for several pieces of background music heard in stages. It was announced at the Tokyo Games Show that there will be a Sonic Forces Hi-Res Collection featuring pieces performed by the London Symphony Orchestra. According to Shun Nakamura, the orchestra was used to emphasize the weight in pieces such as the title theme and the world map.

On 31 August 2017, Sonic the Hedgehog's official Twitter account announced the official release date of Sonic Forces, along with a physical bonus edition of the game available for pre-ordering for the PlayStation 4, Xbox One and the Nintendo Switch.

For the appearance of Sonic Forces on Tokyo Game Show 2017, limited merchandise related to the game was handed out to the attendees. These included Sonic Forces posters, Sonic Forces-themed t-shirts, Sonic Mania-themed chopsticks, and Sonic Forces and Mania-themed keychains. Also, on 12 September 2017, a racing mobile game tie-in to Sonic Forces entitled Sonic Forces: Speed Battle received a soft launch for iOS and Android.

On 19 September 2017, pre-orders for a digital bonus edition of the game titled Sonic Forces Digital Bonus Edition was made available. This bundle includes the full Sonic Forces game, the Shadow costume, the "Sega/Atlus" Pack, and the "Episode Shadow" DLC.

On 22 September 2017 during the Tokyo Game Show event for Sega, they announced there will be a Sonic Forces promotional collab at Hooter restaurants in Tokyo from 16 October 2017 to 10 December 2017. During this time, customers could order a Chili dog meal and collect one of four specially designed coasters. These coasters were of Modern and Classic Sonic, Tails and Knuckles, Shadow and Infinite, and the official promoted wolf and cat forms of the Avatar. At dinner time, special dances were held to the main theme of Sonic Forces, "Fist Bump". They also announced a cross promotion with Hatsune Miku: Project DIVA Future Tone to be held in six different locations in Japan from 7 October 2017 to 5 November 2017. Attendees of the events received Sonic Forces posters and Project DIVA Future Tone badges. Those preordering the game would also receive a costume of Shadow the Hedgehog for the Avatar.

On 12 October 2017, Sega released the first issue in the Sonic Forces digital comic series, a four-issue digital comic publication featuring stories that serve as prequels to the game's events.

Pre-release
The International Business Times praised Sega's approach of announcing and releasing the duo of Sonic Forces and Sonic Mania in the same year, stating that catering to the new fans with Forces while catering to the old-school fans with Mania could help repair the series's poor reputation with more recent releases, and in turn lead to a "Sonic Renaissance" era.

Reception following the game's showing at the E3 2017 has been mixed to favorable. Heather Alexandra from Kotaku praised the game's three gameplay styles and the Egg Dragoon boss battle, though she felt that the platforming side of it was in need of some tweaking. James Galizio from TechRaptor also praised the Egg Dragoon battle, calling it a "very interesting Boss Battle", but remarked that there were some slow-downs in the demo for the Nintendo Switch's handheld mode. Ed McGlone from Twinfinite found the Avatar's gameplay clunky; expressing the feeling that the gravity was not so prepared in the demo, and the Avatar would instantly be pulled onto the ground after a jump. However, he found Modern Sonic's gameplay a smoother version of Sonic Generations, with the Boosting mechanic being more refined while also praising the storyline's direction. Alex Olney of NintendoLife was more critical, thinking that the demo version of the game lacked focus and direction while also calling Modern Sonic's gameplay "dry and boring", and the Avatar stages an "afterthought". Sonic Forces also earned the nomination award for Peoples Choice at Gamescom 2017 by IGN. At the end, it came in at 2nd place.

The Nintendo Switch's version of the demo has a couple of issues reported compared to other consoles. This includes a lower FPS, lower-quality texture, effects and models, and lowered resolutions.

Post-release
Polygon gave Sonic Forces a mixed review of 5/10. The website praised the game's visuals, but criticized its repetitive boss fights and felt the game did not advance the series' design. They also took issue in the ranking system, rewarding players for completing stages in a fast manner rather then exploring the stage for collectibles. The four reviewers of Famitsu were more positive, giving the game a 35/40, praising the character creation system and soundtrack.
