House Of The Dead: Overkill was amazing, and typing words on your keyboard rather than using a WiiMote has made it better in absolutely every respect. It's utterly brilliant both as an ironic grindhouse homage and viable typing trailer, while its numerous DLC word banks make the experience even more surreal. The £6.99 Thou Filthy Love Collection won't net you all of the DLC, but will net you the best of it alongside the game itself at a £12 saving. Thanks to Jas10 @ HUKD!
Mind you, Amazon.com includes it in an amazing SEGA bundle if you're willing to slightly fudge your address (and pretend to be an American citizen).
