"Tip: Have 3 or 4 Players"
When you start the level, run to the stairs in front, not on right. Then kill those 2 dead guards quick then go in the middle of the stair way, then fire at the dead teens, dogs, and guards that are around you. Do the same thing with the other stairs to your right, but before that, get the shotgun and machine gun to the left. Then go into the kitchen, go to the right, jump on the table right next to the right wall, then jump on the big oven so they can't hurt you. After that go through the single door way in front to get the key, waste those zombies quick for no damage then get back in the room. Then in the other room, fight like crazy with your sword/knife/axe at those guys who shoot those poison darts at you. Well, that's how you get pass the beginning of Meathill1, good luck on the rest.
