I recently tried am on my server right now pitting a firing line of these things against a squad of twelve slow moving zombies. They have a very low range of sight apparently and the slow firing speed doesn't help. Lol, maybe we need a zombie defence specific sentry. this seems like it would only be good against ditzy, easily excitable players, not cold perfectable Ai zombies. Faster firing speed and wider range of sight version pl0x.
