House of the Dead Overkill is good fun, the only downside is it stutters quite badly, and it's very noticable to me. When a lot of zombies are on screen, or it's doing something intensive like explosions or fire, the game freezes for a split second and then continues. It is quite a shame because it gets annoying and becomes even more noticable once you've experienced it, because you're watching for it to do it again. Other than that /thumbsup
