Mainly I eliminated ray gun right away for reason it screws you over when zombies are close and becomes 2 hit k.o in later lvls. Then the next one would winters howl is out mainly because you have to unload a clip to freeze a zombie so yeah. Then the next 2 are by FAR the best. But I'll eliminate the DG-2 mainly because its possible to miss and thundergun haha pretty hard to miss. I like them both since i do the run and gun technique.
