The game allows the player to play as either the Maximals or the Predacons in a series of missions to sabotage the other side's attempts at gaining a tactical advantage in the Beast Wars. There are six playable characters on each side, one unlockable by finding a stasis pod in a specific level and the other only accessible in Rescue missions, each with their own unique strengths and weaknesses, and they all have both a health meter and an Energon tolerance meter.
