One of Rogue Warrior's crowning achievements may end up being its elaborate multiplayer mode. Up to 24 people will be able to knife each other in the face in 10 different gameplay variants - that's nothing new, but the tile-based level construction could make it so you never play the same match twice.
Before a multiplayer game, both sides literally construct the area they're about to kill each other in. Neither side knows which tiles the other has picked, so every scrap should unfold differently than those before it. Given all the tile combinations, it's possible to create more than 200 maps at any time, each with different buildings, tunnels and obstacles to sift through.
