The game is a single-player mission-based action title built around side-scrolling stages. Players guide Ben through different regions, fighting waves of enemies, breaking obstacles, and solving environmental puzzles. The Omnitrix lets Ben transform into aliens with distinct strengths, such as brute force, speed, ranged attacks, or traversal utility. At first, transformations are limited by energy, but defeating bosses unlocks new forms and eventually the Master Control, which removes the time limit and allows free switching. Omnitrix points can be spent on attack combos, while collectibles and pickups provide temporary boosts, invincibility, or faster recharge.

Ben Tennyson

The main hero who uses the Omnitrix to fight enemies and overcome obstacles.

Vilgax

The primary villain seeking the Omnitrix DNA samples to carry out his plan to destroy the world.

Use the right alien form for the situation instead of relying on one favorite form. Save faster or stronger forms for tough enemy groups and bosses, and use utility forms to handle traversal or puzzle sections. Collect Omnitrix points early to unlock useful combos, since they improve crowd control and damage output. Keep an eye out for the three hidden Sumo Slammer cards in each main stage, as they unlock extra content. Once Master Control is available, switch forms freely to adapt to every fight.

Collect all three hidden Sumo Slammer cards in a main level to unlock bonus features such as movie clips.

Defeat bosses to unlock new alien forms; later progression grants Master Control, enabling unlimited transformations and free switching.
