Boss Rush is a feature in Psi-Ops: The Mindgate Conspiracy, that allows the player to play all of the Boss Fights.

The Boss Rush works by placing the player in the first boss fight (Jov Leonov). After the player wins this boss fight, the next boss fight (Edgar Barrett) comes on. This continues until all bosses are fought.

Boss rush is unlocked after the player wins the game, and has unlocked all of the boss fights.
