While Microsoft remains staunchly anti-keyboard and mouse for the Xbox 360, a third party has stepped up and released an adapter that allows you to play your favorite shooters PC-style. The adapter will accept PS/2 and USB keyboards and mice in addition to (oddly) Playstation 2 controllers.
The freedom to choose your control scheme doesn't come cheap, though: you'll have to fork over $79 for this adapter.
