DEFCON

Thanks to Britain-based indie developer Introversion, you can play apocalyptic war games on your home PC? DEFCON isn't an official movie tie-in, but it might as well be. It's a real-time strategy game from the folks responsible for the IGF 2006 award-winning Darwinia, which renders the world in the same dehumanized 1980s vector graphics you'll recognize from the film's ominous NORAD war room screens.

Command a range of conventional and nuclear weaponry, which you deploy in stages as the clock ticks down from DEFCON 5 to DEFCON 1, at which point the nuclear gloves come off. You can challenge the computer or go nose-cone-to-nose-cone with up to six players online, but as for winning, let's just say the player who loses least, loses best. And make no mistake...everybody loses.
