ok on first level put on on the first little indent then torwards the end just make a barrage of tack towers and buy supers when u get the chance oh, and UPGRADE!
ok i was on level 12 on boxy, the whole screen was filled, and all i had was a lone pistol. i ran out there shooting everything, two demons came out at the same time, they took a bite out of my limb, and they left me here to bleed, and let me tell you all i know...BEWARE THE ZOMBIE!!!
pudding, here is a good tactic, make the hero by himself move up to the other teams terroritory, then bring him back and all the enemies will follow him, after that, Have your defense line attack the offending team and then charge up.
