Crash Bandicoot 2: Cortex Strikes Back is the second game in the Crash Bandicoot series, and the sequel to the original game. The gameplay is largely similar to that of the original, as players make their way through a limited environment whilst breaking crates that contains bonuses. The goal of the game is to gather 25 crystals for Crash's nemesis, Doctor Neo Cortex. The crystals are scattered between 25 different levels accessible via Warp Rooms, which are hub areas of the game. A level is cleared by collecting its respective crystal and reaching the end of its path, which returns Crash to the Warp Room.
