While last year was the 30th anniversary of Pac-Man, 2011 is the 30th birthday of another Namco Bandai franchise: Galaga. Celebrating both, the company announced a new release, Pac-Man & Galaga Dimensions, coming on a single cartridge to the Nintendo 3DS.

Shown off in the latest issue of Japanese magazine Famitsu, the game will consist of two 3D adaptations called Galaga 3D Impact and Pac-Man Tilt. The former transforms space-shooting arcade game to a 3D shooter from the perspective of the ship's cockpit.

Andriasang, which translated details from the magazine, says, "The action is on rails, with your ship flying automatically through a fixed course. You'll have to simply look around and aim. This is done via gyro controls, where you physically move the system around to turn your viewpoint."

Pac-Man Tilt is less like the traditional maze games most are familiar with, dropping the yellow mascot into a side-scrolling game in which you jump and swing through stages filled with gimmick obstacles (e.g. tilting the 3DS to swing a platform Pac-Man is standing on, sending him flying into the air).

Namco Bandai hasn't yet announced a release date for Pac-Man & Galaga Dimensions. Judging by the initial screenshots and concepts, I wouldn't be surprised if non stereoscopic 3D versions of these ended up on the iPhone soon.
