My favorite map is Two Towers. I like it a lot. My close second is Snow Valley. Sorry guys, Junk Flea is my least favorite. I don't enjoy non-stop action. I can't stand it to leave my spawn point, make it two steps, and get cut down. I don't particularly enjoy the sweet savor of a victorious kill, only to be shot from behind a second later.
But Two Towers... ah two towers. How I enjoy the multiple routes to get around, all the little hiding spots for a sniper, and the blind alley ways where I can camp and wait for someone to run by oblivious to me as I shoot them in the back. Muahahahahahahhaha
