Probably the best RTS that has ever been developed!
If you like horror games like system shock 2 and roguelikes, give this a try. For a game with such simple graphics, it is truly anxiety-inducing, but also fairly acessible, with reasonable difficulty adjustments. In my opinion the only thing overtly lacking is the story, which is not the most engaging type of thing, but it is interesting overall. Stellar atmosphere. Wish just that there were more drone types :-)
