The game uses a side-scrolling perspective. Players move through linear stages, defeat enemies, avoid hazards, collect items, and reach the stage exit while using Ben’s alien forms to handle different situations.

Progression is organized around a sequence of missions. Transformations provide different attacks and movement abilities, so changing forms is important during combat and environmental obstacles. The Nintendo DS version focuses on straightforward action rather than extensive exploration or multiplayer modes.

Learn which alien form is best suited to each enemy or obstacle instead of relying on one transformation throughout a stage.

Keep moving during crowded fights, watch for environmental hazards, and explore side paths when they are safe; useful items and alternate routes can be easy to miss.
