Place the fab in the spawn entrance like so
Sorry, this Game Clip has been removed
If you have done it right
NO enemies can enter the spawn apart from,Juvies that jump in the window,Sentinals can fly in & Carriers can fit(but snatchers can't go figure).The other bonus is all the power from every kill will glitch into the little game room for you as long as everybody is in or at the entrance for the spawn.Just a fence or 2 near the windows & a sentry or 2 at the back wall for just incase a sentinal tries to make it in the door.A couple of Heavies with dropshots will make a killing here & you could always strike a heap with a sniper.
