Ben 10: Omniverse 2

Ben Tennyson, a 16-year-old with the Omnitrix, leads the fight against Incursean invaders in this 2013 action-adventure game. Players transform between multiple aliens like Big Chill, Four Arms, and Swampfire to battle amphibian-like enemies in side-scrolling levels and beat-'em-up arenas, switching forms rapidly to overcome obstacles and collect DNA orbs. The story follows Ben's quest to save Earth after being shot into space, teaming with Rook Blonko and Azmuth in chase and infiltration sequences aboard Incursean ships. Key mechanics include combo attacks, charged super abilities, and Omnitrix upgrades by alien class. It stands out as the fastest Ben 10 title with authentic voices from the Omniverse series and unique 3DS side-scrolling platformer elements like touch-screen alien selection.
