G-Force is a licensed game based on the movie of the same name, where you play as Darwin, a member of a secret government organization consisting of guinea pigs. Your mission is to defend the evil industrial magnate Saber, who manipulates home appliances and uses them as weapons.
The gameplay is mostly action-packed, with plenty of fights against Saber's minions using various guns and gadgets like a jet pack, electronic whip, or grappling hook. However, there are also puzzles to solve, many of which require the help of Mooch, a fly that can be summoned at any time. Mooch can be used to reach high grounds, deactivate electronic devices, fly through small holes, and even slow down time to pass through fast-moving obstacles.
Throughout the game, you can collect computer chips and hidden disks that can be used to upgrade your weapons, refresh ammo and health, or switch to an infrared view to scan objects for additional information.
The Wii version of G-Force has an optional playing mode for 3D glasses on the PlayStation 3 and Xbox 360 versions, although not available on the Wii itself.
