Civil War
Another great map made by Michael Coyle. This one is pretty large but built on a big round oval style. (I think, I was so busy dodging the bobs that I rarely got a chance to check the map mode) Whatever you do, don't leave the aliens on. I was trying to do a walkthru and was nailed in the back by the bobs. The title should give you a hint...you can witness the event the map is based on if you leave aliens on. A good download and some really nice landscape visuals.
