Defend the Resistance's HQ from a mutant attack.
Will you be able to hold the position? In order to do it, you'll have missiles, laser and superattack weapons like the pig-bomb. Don't let the mutants destroy HQ, pick up the gems and medals they'll leave in their wake when you destroy them and accomplish the missions we suggest (kills two mutants with one shot, use all the weapons in a single battle, etc...)
