I was giving guns a go and went out with my trusty shot gun to do some work. Everything was going as expected until I ran out of ammo. My character became stuck in the half crouch position, as if I were holding down the right mouse button to aim, and would only move at a slow crawl. I tried switching weapons, moving in/out of the full crouch position but nothing worked. The zombies easily caught me and delivered a savage beat down.
