"Great Wall" Cheat from SDOG782
If your enemy is constantly sending units to attack your base, build a sand bag wall FULLY SURROUNDING their base. The AI will not go any farther than that wall, so therefore they can't attack you or get tiberium! But don't get to close with your units or they will attack your units. Build up your forces for one massive attack on the enemy base.
