Debo2792, it is not a glitch, it is the zombie slayer skill.
BTW good game.
This is one of the best zombie games I've ever played on Newgrounds, it's actually got killing zombies being fun. No RTS strategy, no complicating enemies just fun zombie killing with a small story, I'll take it!
The concept of these game is ingenious, a zombie horde in the 1902 London. Never expected this, and its addicting.
Really like this game, run, escape out of the zombies, zombies, two guns and infinite posibilities to kill Â´em all , 5 stars for this awesome game
