Gameplay consists of action and puzzle-solving that revolves around the skills of alien forms. For example, Ben might need to change into his Humungousaur form to break through doors, or use Swampfire to ignite flammable substances. Each form has different combinations and special attacks that it can execute, and Ben can unlock new abilities by defeating enemies and collecting glowing energy orbs. However, using a form's innate abilities drains energy from Ben's Omnitrix meter, preventing them from continually being used until the meter can recharge.
