Cutthroat Cove

Next level >>

Cutthroat Cove is the fourth level in Sonic Boom: Fire & Ice. It is an island of coves, untamed swamps and villages hosting what appears to be a lawless community for pirates. Due to Dr. Eggman, the island's environment was messed up by the by-products from the doctor's mining operations on Ragna Rock. This pollution was brought to an end by Team Sonic.



Cutthroat Cove's World Map.

Cutthroat Cove is set at night during a full moon. At the coast is an old-style harbor with cannons and old ships. Within the island is a moss-filled cave held up by natural pillars, and a murky swamp with a village amongst the large mangrove trees and waters. Structures there are connected by old bridges with poles adorned with skulls.

The first two adventure levels take place in the mangrove swamp. The paths here consist of moss-covered tree blocks and occasional tree trunks that wind between colossal tree roots. Along them are red thorns, Nuphar-like bushes, abandoned plank roads, moss slaps hanging from the ceiling, bottles, barrels, and poles with hedgehog skulls. Giant, twisted mangrove trees in a green swamp can also be seen in the background.

The last two adventure levels take place in an old-fashioned pirating town of brick and wooden framework. Here, giant mangrove trees, buildings on steep hills, and the night-shrouded coast appear in the background. The paths themselves lead across rooftops, through alleys and passages, and over walls. Along them are Nuphar-like bushes, various barrels, lanterns, metal spikes and broken brick walls.


While mining on Ragna Rock, Eggman would pipe the messy by-products from his operation off to Cutthroat Cove. This lead to the creation of fissures emitting Fire and Ice energies, which would mess up the island's environment.

Having arrived Cutthroat Cove to contain the local fissures which were destroying the environment, Team Sonic found the biggest fissure yet. Upon scanning it, Tails discovered it held traces of a new mineral which Dr. Eggman called Ragnium. Immediately after, Tails detected a moving Ragnium source, prompting Team Sonic to chase after it to uncover the source of the fissures.

Catching up to the source, Team Sonic dicovered it was D-Fekt, who was covered in Ragnium residues. Upon seeing Team Sonic, D-Fekt had a flashback of the events leading up to this moment: having been created by Eggman to mine Ragnium via magnetism, D-Fekt was labeled a failure by Eggman when his magnets would not attract Ragnium. However, D-Fekt secretly discovered he could magnetize everything else and so became determined to beat Sonic and Team Sonic to please his creator. Back in the present, D-Fekt made his escape, only for Team Sonic to give chase.


Cutthroat Cove's adventure levels, like the others, are divided into two parts (the foreground and background) that run parallel to each other, which can be traveled between with the Bounce Pad. Other than the Bounce Pads, standard gimmicks here include Boost Pads, Enerbeam Swings, and disappearing platforms. There are also cannons for firing the playable character which can be fired with DSB and move around on their own. Most noticeable though, are the blocks of ice/water that can be turned solid or intangible by touching them while using Fire/Ice Mode. There are also wicks which can be ignited with Fire Mode.

Hazardous obstacles in the adventure levels include stationary rollers with spikes, moving and non-moving spiked blocks (some of which form traps), and spiked surfaces. Touching such obstacles will damage the player and return the characters to an earlier position. The adventure levels also have collectibles scattered about which unlock extra content if collected, breakable obstacles that give extra Rings, and Challenge Room entrances.

Like other adventure levels, Cutthroat Cove's have several character-specific gimmicks for the playable characters. These include dash blocks for Sonic, Air Vents for Tails, pillars for Amy, Burrow spots for Knuckles, and Boomerang Switches for Sticks. In addition, Cutthroat Cove features three bonus levels, each with different gameplay mechanics.


Cutthroat Swamp

Cutthroat Swamp is Cutthroat Cove's first adventure level, which takes place in the swamp. It becomes available after unlocking Cutthroat Cove.

At the start, follow the rightward paths to the first Checkpoint. There, one can go left to take a looping path. Proceeding in the rightward direction at this point instead however will eventually take the player to a drop down on a Bounce Pad before the third Checkpoint. Here, one must go right again. Along this way, the player can reach an upward path with the first cannon encountered after the third Checkpoint to get to a loop past Boneyard Hollow. Should the player continue down the rightward paths instead, they will arrive at the fissure.

At the start, go first down the rightward paths. Upon reaching the first Boomerang Switch after using two cannons, the player can take the left path to reach a looping path. If the right path is taken instead, keep going in the rightward direction. After a series of three cannons on this path, there will be another path with a dash block on the left which leads through a loop past Cypress Cavern. Should the player stick to rightward paths though, they will find the fissure.
