Who knew Pac-Man: Championship Edition would be so good? The surprise XBLA hit has inspired yet another modern Namco remake, Galaga: Legions. Legions will arrive exclusively on XBLA, and will come from the same team that brought us Pac-Man: CE. Expect the same kind of visual redesign and addictive retro gameplay. With this and Space Invaders Extreme (DS/PSP), the retro shooter is back in full force.
