(adsbygoogle = window.adsbygoogle || []).push({}); so most of us know about the bowie knife glitch to get three guns, which involves you getting revived by a teammate. well in solo if you PaP the thundergun and PaP another gun and then you get quick revive and do the bowie knife glitch then you could have 2 Pack a punched guns and say the mp40 when doing the run around of the map. i think the most useful other gun to PaP would be the spas so you could blast the zombies if the get infront of you when your going through a doorway and not have to use a thundergun shot to kill one guy.
