Sonic Forces: Speed Battle

Sonic Forces: Speed Battle, also referred to as Sonic Forces is a 2017 online battle-racing game. It was developed by Sega Europe and Hardlight for the Android and iOS mobile devices to promote the then-upcoming Sonic Forces at the time. It was soft-launched by Sega on the App Store (and eventually Google Play) on 11 September 2017 in the Philippines and on 20 September 2017 in Canada. It was officially released worldwide on 2 November 2017 for iOS and on 15 November 2017 for Android.

Development
Sonic Forces: Speed Battle was first in development in June 2016 after analyzing the latest capabilities of present-day phones. It began as a prototype by Hardlight, checking if synchronous gameplay would work as well as they expected. These early prototypes used existing tech and games as testing grounds for the gameplay, like Sonic Dash 2: Sonic Boom. The game was originally planned for the Sonic Boom franchise, using the main cast of characters from Team Sonic.

From the beginning of the project, Hardlight wanted the game to have flexible levels for more expansive gameplay. For this, they developed a modular system that allowed them to create any track piece they wanted. Hardlight also wanted, right from the start, for the game to be a skill-based, global multiplayer. While relying on the classic staples in the Sonic series, branching paths on the tracks were added to make the game more exciting and unique. Extra care was also made to ensure the levels fit the mobile environment. During development, the staff focused on making the tracks feel appropriate before polishing their design.

Hardlight pitched their idea to Sonic Team back in 2016 when the latter was looking for a mobile game. After discussing with Takashi Iizuka, the teams settled on what would become Sonic Forces: Speed Battle. Hardlight subsequently expanded their team while working on the environments and metagame. After being in development for about a year, Sonic Forces: Speed Battle received a soft launch so Hardlight could test the game and work out the remaining bugs before the global launch. The game was scheduled to have three Zones with twelve tracks for its global launch, with more Zones being planned on being developed. It was revealed on 16 March 2018 that Mystic Jungle would appear as a new Zone in an upcoming update.

Gameplay
The gameplay of Sonic Forces: Speed Battle is very similar to that of Sonic Dash and Sonic Dash 2: Sonic Boom, with a competition element from Sonic Rivals added to it. Instead of an endless runner, it is a basic runner where players each choose a character and race against each other online in real-time on one of many finite tracks selected at random, based upon City, Green Hill, Sky Sanctuary, and Mystic Jungle. Characters are unlocked over time by reaching certain positions when completing races. During races, players can collect up to 100 Gold Rings (which serve to increase their movement speed) and dodge obstacles as they progress to reach the goal (represented by the "Phantom Ruby Prototype"). Getting hit by obstacles will cause the player to lose Rings and slow down momentarily. After a race, the players get to keep the Rings they have collected.

Currently, there are twenty playable characters in the game. Characters are unlocked over time by reaching certain positions when completing races.

While racing, the playable characters are always running forward automatically. At the same time, the players can use the Spin Jump and Slide to dodge obstacles and destroy enemies. They can also interact with other paths, normally utilizing rails. Each character has different levels of Speed, Acceleration and Strength stats, as well as a unique selection of power-ups that can be obtained from Item Boxes along the race courses. These items can be used for the players' own benefit or against their opponents.

At the end of the race, players can earn Battle Chests which grant a range of Cards to a particular character. In addition, the first and second place finishers receive a Victory Chest which can be unlocked to earn larger bonuses, such as a large number of Rings or Cards for multiple characters each. Red Star Rings are featured as premium currency which can be obtained from Free Chests or purchased using real money which can be used to purchase additional Rings, Chests or unlock Victory Chests that are already acquired. Free Chests are distributed to the player every four hours, and up to two of them can be stored at a time. Players can view each others' Trophies in the online leaderboards.

Collecting enough cards for a character will allow the player to level it up using Gold Rings, which improves the racer's items' effects and the number of Rings they start the race with.

Based on which position they finish the race in, players will then gain or lose Trophies, a numerical matchmaking ranking system akin to an Elo rating system in other competitive games. This matchmaking gameplay mechanic is part of the "Tier" system, which determines which courses the player can play on and the number of rewards the player can earn from Chests.

By upgrading characters, players are awarded with XP, which will increase their level:

When a player's level increases, their Ring Boost and Resistance also increase. Ring Boost increases the maximum amount of speed the player can gain by collecting Rings in Sonic Forces: Speed Battle. The higher the player's Ring Boost is, the faster they can go. Resistance, on the other hand, decreases the effect attacks from other players have on the player's character. The higher the player's resistance is, the greater the reduction will be.

Missions
Every 8 hours, every player will be given a new random mission (up to three of which can be left uncompleted at a time) which awards Rings or Red Star Rings, and cards for upgrading characters. These missions range from tasks such as "Use Explosive Mines successfully 10 times." to "Star Runner" missions, which require playing five races with a certain character.

Seasons
Seasons are 30-day long events that take place in Sonic Forces: Speed Battle. First unlocked in tier 4, they can be entered by finishing a race in first place at least 3 times during that season and will award a chest with a certain amount of cards at the end of the 30-day period, with the number of cards increasing the higher the player's tier. Upon reaching the first prestige tier (tier 8) at 4,000 Trophies, any trophies earned past that number will be converted into prestige points at the end of the season and reset back to 4,000. These points are shown on a separate leaderboard, which only updates at the end of each season.

Events
Events appear for special occasions such as Halloween, and contain special missions that unlock unique characters (classified as "Special"). Completion of an event mission will reward the player with a random amount of cards for the Special character as well as cards for one random common character. Players must then wait 8 hours for a new mission to appear in order to unlock more cards for the unique character, or use Red Star Rings to unlock another mission immediately (the cost of this increases every time you unlock another mission unless 8 hours are allowed to pass). Players have one week unlock each special character before the event ends and they become unobtainable.

Upgrades

Trivia

 * Prior to version 1.0.1, the game files as well as a teaser image posted in the in-game's news bulletin hinted that Silver, Classic Sonic, Metal Sonic, Zavok, and Chaos were going to be added as playable characters at a future date.
 * This is the first Sonic Dash-based game to not to be an endless runner title.
 * The initial main cast of the game (except for the inclusion of Amy) is the same as Sonic Runners Adventure, another mobile game released the same year.
 * The music for the levels, provided by Tomoya Ohtani, are the themes from Lost Valley and from Luminous Forest in Sonic Forces, the latter of which only plays during the Mystic Jungle stages.

 * "You think you can keep up with me?" is one of Dr. Eggman's lines of dialogue when racing against Tails in Speed Highway from Sonic Adventure.
 * "You think you can beat me?" is derived from one of Robotnik's phrases, "Do you think you can beat me?" when playing in the two-player mode in Sonic Adventure 2.
 * "The ultimate lifeform" is a title that belongs to Shadow the Hedgehog.
 * "Long time no see" is a phrase that has been constantly used throughout the series, namely Sonic Adventure, Sonic Adventure 2, Sonic Heroes, Shadow the Hedgehog, Sonic the Hedgehog (2006), Sonic Riders: Zero Gravity, and Sonic Forces itself.

 * Teaser images featuring single distorted silhouettes of potential new characters to be added in future updates were posted on the official SEGA HARDlight social media on 12 January 2018 and 17 February 2018. The first character was revealed to be Blaze the Cat on 17 January 2018 and the second was revealed to be Cream the Rabbit, along with Cheese, on 22 February 2018.
