What blows up doesn’t necessarily fall down in Inversion, a topsy turvy shooter that plays like Gears of War with one confounding gimmick: variable gravity. Alien technology has transformed the urban battlefield into a vertigo-inducing M. C. Escher painting. Walls and ceilings have their own gravitational fields, and the concepts of up and down no longer apply. Adding to the chaos, your warrior wields a “Gravlink” weapon that nullifies the gravity around enemies and objects, letting you pluck alien invaders from behind cover or chuck cars across the battlefield. Gravlink gimmickry carries over into the multiplayer matches, too. Nothing beats pinning an unsuspecting newbie to the ground—except maybe dropping a car on him.
