I think it would be pretty fun to have a multiplayer stage on the oil derrick. The single player on it looks cool http://www.youtube.com/watch?v=SgyCWglLvsc&feature=relatedso anyone else think it would make a fun MP stage.
Yes, I think it would be a great map, and one that should be fairly easy to make. It would be great if they kept the Leviathan in it as a map hazard (or some kind of bonus or penalty) too. Imagine what you would see as your character is eaten by the creature.
Just want to clarify -- by simple, I mean most of it has already been created for the single player campaign. There shouldn't be too much work needed to move what already exists in to a multiplayer environment.
