Biology Battle Xbox 360 Cheats
How to use these cheats
Button names refer to the Xbox controller — A, B, X, Y, the LB/RB bumpers, LT/RT triggers and the D-pad. Unless told otherwise, enter codes from the pause or options menu, or while playing. Some cheats disable achievements for that save — keep a separate save before you start.
Biology Battle is an Xbox Live Indie Games twin-stick shooter, so it has no achievements and only one widely confirmed secret.
Increased conflict level: Select Global Challenge mode from the main menu, then press A in the lobby to reach the pre-game screen showing the controls, tips and the Press A to start message. Hold Y and press A. A woman's voice saying Increasing conflict level confirms the code. Enemies become faster, appear in greater numbers and spawn more quickly.
Harder runs: The conflict level trick stacks with the game's already brutal later waves, so it works best as a score-chasing challenge once you know the arena layouts.
