A map where you need to survive. Here the player needs to survive 30 rounds, but that doesn't mean that the player can not counter attack the AI. If you want to attack, be CAREFUL of the way that you attack. The AI will never stop producing new units, so you have to be more to defensive then offensive. If you build stealths, destroy all the blockades on the sides and attack the turrets. Stealth tanks aren´t produced by AI, so don´t worry about receiving surprise attacks.
