Warcraft 3: Demon Square TD! #1
I think teal had the better strategy in this one, but I think that u mainly just need 4 players to play this map with each player being in the corners. It is definitely one-sided for the guys that get spawns in the corners and the guys that build in the middle will get less feed.
