Robots occasionally drop power-ups that temporarily grant superhuman powers. Rockets shot by robots can also be punched, if timed correctly, back into their metal faces. With melee combat, players can (and should) punch robots to knock them back and inflict damage. Revolvers, rocket launchers, assault rifles, flamethrowers, SMGs, and shotguns all beg to be used, not to mention the freeze ray, gnome launcher, and a cat carrier that shoots an exploding robot decoy. For the truly hardcore, there are three difficulty modes to keep players hurting. Hunker down in Survival missions – claustrophobic levels where the only object is to outlast waves of robot hordes.
MissionsPush forward through robot territory in Traversal missions – huge levels that end in epic robot boss battles.
Players also level up and gain XP by killing robots, which grants them access to new missions and equipment, as well as increase Walter’s damage and health.
