This building is required if you wish to attack another person. There is a limited capacity to the number of units able to warp at a time. You also need Warps to send your unit to another player's base, which is used after you attack. Warps must be refilled for about 30 minutes in order to attack again. A level 1 Warp Gate has 3 warps, and will NOT have more if you level it up. Once your units have destroyed a base, surviving units will go back to the staging area while the ones that died won't. Upgrading your Warp Gate will raise the life and capacity of the Gate. You can have another warp gate in your Aurora-1; and another one in your main once you get a lvl 11 CC.
