Lots-a-Brutes: (Yuri Side Only!):
Get the genetic Mutator ready. Turn super Weapons on and start a game. Build about 5-10 slave miners and send them all to one ore patch. Once all slave's are in range of the mutator click and all slaves turn into brutes. The slaves will be replaced and you could have 50 brutes!!(if u need cash, grind em!).
