The first 1/3 of the game features linear levels, with the player's goal being to make it from the start of the level to the end. About 1/3 of the way into the game, the player acquires a cloning machine that allows them and their squad members to respawn from death an infinite number of times. At this point, the only way to "lose" the game is to allow the enemy to capture and destroy the player's cloning machine. All levels from this point on are based on a capture the flag style of gameplay, with the rebel and Grathius teams starting on opposite sides of a non-linear level, each one tasked with capturing the other's cloning device.
