Anyone else ever played this one? It is the must frustrating/exhilarating game I've played in a long time, and its turn based.

Basically, both teams tell their team what to do at the same time. Once you have it ironed out, the teams just go. Everything is broken down into 10s chunks, and you'll spend an hour coming up with the most perfect, intricate plan, and when some guy you didn't see pops his head through a window and takes out everyone you had pointing the other way, you'll curse and scream and toss your keyboard through the monitor.

If anyone has ever played the Vicksberg War Game, it reminds me of that, just not as lopsided.
