There's another quirk in this Rogue Warrior game.
There are no multiplayer maps.
No maps. None.
What are in the game are a set of 'tiles'. Sections which have folliage, buildings, etc. Like miniature maps themselves. And when a multiplayer game is started, the tiles are laid in a random pattern. Because the tiles aren't actually tiny, you can still get a familliarity from experience, but there's no 'Oh, I remember there was this great camping spot over here...' and such anymore. There's probably going to be some pre-set tile combinations and a mode to use that as set 'maps', and an editor so the host can design a layout himself and play on that, but by and large, the random map multiplayer is probably going to be the draw.
