go to survival mode, wait for bosses, shoot them withrage bullets and keep hitting them with rage bullets to make them heal, easy survival achievment and its funny to see 50+ zombies fighting each other.
ermh,i was playing on the 4th mission i think(the one you need to go north) and the clock bugged, first wave came, killed them and now no waves appear(eventhough i still have more than 30 zombies north)
Spent all day clearing zombies out of the hospital. WE killed as many as we could,but one got Soldier Rogers when SHE went behind a building to take a piss. Damn Fool.
I lolled.
