Overkill is an over-the-top, B-movie, pulp fiction-style take on the House of the Dead series. Played from a first-person perspective, the game's seemingly simple goal is to shoot at the zombies, mutants, and other unearthly horrors that come into view, before they can get close enough to take a bite. The lead character quips sardonic comments and macabre jokes, and innocent civilians flee the carnage as he blasts a swath of righteous gore through the writhing hordes. The play mechanics are of the on-rails shooter style used in other House of the Dead games.<br><br>As in the well-received House of the Dead 2 & 3 remake for Wii, players aim and fire using the Wii Remote, while their characters automatically move forward through the level, pausing at key locations for special challenges and scripted events. The action is set to a rousing pace, with swarming undead and surprise attacks to keep the tension on edge. The motion-sensitive controls also play a role when the creepies get too close for comfort: with a swing of the controller, players can pistol-whip a zombie or smack back a mutant with the stock of their shotgun. Two-player cooperative play is supported, for side-by-side shooting.
