You’re a small, fleshy human with a jetpack and a gun, and your opponent is a robot centerfold that dwarfs a city block. The robot — called a Titan — tries to cut you apart with lasers and missiles powerful enough to crumble the buildings you’re standing on. You pick off the Titan’s cannons, fry away its carbon fiber armor, target a joint, and tear off a claw, leaving it writhing. Your furious opponent spews raw plasma at you, so you shoot up a force field and duck behind it. Who will win? The crowd cheers your intimate-yet-deadly dance.
