http://www.armorgames.com/games/thelaststand_popup.html Make sure you search for guns until you get the 45smg, it is the best gun, all the other guns aren't as good. Just stay around the bottom and spray as the zombies come in. Once you have the smg, try to search and get full survivors. The best backup gunis the shotgun, it can wipe the screen, but you have to wait for it to reload all 8 shells to swap back to the smg.
My favourite combo was the hunting rifle and sawn off shotgun. Until you get to the last few levels and pick up that beast of a gun. <forsyth>Good game, good game.</forsyth>
I think the sawn off shotgun is the best. I used it within the last 5 levels or so and the wall hasn't had more than 10% damage in each level at all.
