Crash Bandicoot 2: Cortex Strikes Back is the second game in the Crash Bandicoot series, and the sequel to the original game. Crash Bandicoot 2's gameplay is largely similar to that of the original. However, there are some differences. Players make their way through a limited environment whilst breaking crates, each of which containing some kind of bonus. Breaking all of a level's crates earns the player that level's clear gem. The player can also collect additional clear and colored gems by finding and touching them. Colored gems activate secret areas. If the player collects all of the gems in the game, the secret ending is activated.
