Unlock All Combos
When you first begin the game, Ben has a limited number of attacks. As you progress through the game, Ben learns new attacks and pairs them with the ones he already knows. These strings of multiple attacks are known as "combos." Combos are stronger and more effective attacks that do more damage to enemies. Perform combos by tapping the attack button repeatedly. If you are having trouble battling enemies, unlock all of Ben's combos by entering Swampfire, Gwen, Kevin, Ben in the "Bonus Content" menu.
Invincibility
Entering Kevin, Big Chill, Swampfire, Kevin will make Ben invincible. When he, or his current alien form, is attacked by an enemy, Ben will not be damaged. Invincibility allows Ben to make contact with enemies and objects that would normally damage him without losing any health. Use invincibility to fight or run past enemies you find yourself unable to beat.
Infinite Aliens
Ben has the ability to transform into multiple alien forms, each of which has a unique skill. For instance, Swampfire has the ability to control fire and plants, while Big Chill breathes a cold vapor that instantly turns whatever is in its path into ice. Not every alien form is effective during each level. Choose the alien form that best fits the scenario. For instance, if you need to melt some ice, morph into Swampfire and melt it with fire. Unlock all of Ben's alien forms by entering Ben, Swampfire, Gwen, Big Chill in the "Bonus Content" menu.
Level Lord
If you can't get past a certain level, use the Level Lord cheat to skip past it. The Level Lord cheat allows you to skip to the level of your choice at any time during the game. Enter Gwen, Kevin, Big Chill, Gwen in the "Bonus Content" menu to unlock all of the levels.
