Each player has their own base where units spawn ever second. At 400 kills, the player obtains the "level 2" tier of his units. At 800 kills, the players obtains his "level 3" tier so on so forth. The upgrade scheme are 400, 800, 1200, 1600 and 2000. I added 2 extras to the map to make it more interesting. At 3500 and at 5000 kills 1 unit will spawn which I enjoyed tweeking around the editor to make :). The point of the game is to destroyall oponents bases. The game will end in victory for the player who manages to do so.
This is only a test version, some stats may need some ajustments. Please test map and give me feedback or comments.
