Seriously, guys. Orcs Must Die was one of last year's best games. You should be as hyped for OMD2 as you were for Portal 2, ffs. The demo has been awesome, the systems are improved... the only reason you have not to buy this is because you are dead because you are an orc and you have been killed.
Orcs Must Die: funny as hell, insanely enjoyable, and now even better.
I'll be picking up the sequel in a week. I expect you to co-op with me.
