Ben Tennyson
The ten-year-old hero who uses the Omnitrix and changes into alien forms to fight the invasion.
How it plays
The game uses a side-scrolling perspective. Ben travels through linear stages, defeats groups of enemies, avoids hazards, collects items, and reaches an end-of-level confrontation or objective.
The Omnitrix provides access to multiple alien forms. Each form has distinct attacks and traversal abilities, so progression depends on selecting a useful transformation for combat or a particular obstacle. The adventure is structured around story stages with boss encounters and occasional minigame-style sequences.
Plan your run
Use the alien form that best matches the situation instead of relying on one transformation throughout a stage.
Learn enemy attack patterns before committing to close combat, and keep moving when several enemies surround Ben. Explore side paths for useful pickups, then save stronger attacks for bosses and larger groups.

Ben 10: Protector of Earth is an action-adventure beat 'em up developed for Nintendo DS by 1st Playable Productions and published by D3Publisher in 2007. It follows Ben Tennyson as he uses the Omnitrix to stop Vilgax and other threats across locations inspired by the animated series. The game combines side-scrolling combat, platforming, exploration, and short transformation-based challenges. Players switch between several alien forms, each with different attacks and movement abilities, to defeat enemies and overcome environmental obstacles. The DS version was generally recognized as a straightforward adaptation aimed at younger fans, with accessible controls and familiar characters, although its level design and combat were considered relatively simple.
