The most fun I have had with an FPS since the original halflife.
The graphics look great, and actual envvioprments (blown to bits) always look better then fake ones IMO
Sound is convincing, nuff said
Gun selection is not just fun but actually well balanced, making multiplayer a blast, meanwhile single player is stands alone with a story line ludicrous enough that being a sole gunman seems conceivable but interesting enough that I enjoy the cutscenes, alot.
Basically the games nails everything an FPS should have without adding any new gameplay mechanics that would hinder replay value but using the traditional elemnts to achieve a novel experience, becasue apart from the excellent gun roster, the story allows you to feel like a BA MF while blowning away enemies with a far better AI then I have come to expect, but justifiable dumber than a person, beacuse they aren't people, in a bombed out england of antiquety.
