an experiment with teleporting players
or just a shitty map, that's all lol
highest difficulty i recommend is Mayhem (if you are careful and quickly take cover, since the high way part has a lot of snipers, i mean a lot but DW/DS shouldn't be a big deal since there is no actual assault, it's all scripted enemies)
Multiplayer untested! Map is designed for a single player, meaning multiple players cant break stuff.
