Although it stars a video game veteran, Sonic Boom: Shattered Crystal is a departure from previous Sonic games. The core gameplay is co-op, so you'll be able to hook up with your pals for collaborative side-scrolling adventures. There are tons of puzzles to solve and levels to conquer. Playable characters include Tails, Knuckles, Sonic, and the new kid on the block - Sticks the Badger. Together this gang of misfits will battle Lyric, a murderous, ancient snake creature. Lyric has captured Amy and when the crew sets out to rescue her, they discover that Lyric is building an army of evil robots in order to destroy the world.
