In every first person shooter I've played, walking backwards (and maybe side straffing as well whilst walking backwards) has ALWAYS been a useful tactic?
I just wonder how effective it is in real life? I mean, the world/the battlefield isn't exactly smooth, polished plastic like most floors in video games are (no matter what skin is placed over the plastic).
Wouldn't you stumble? Or aim poorly while considering walking backwards blind or even if you worry about stumbling right in the midst of bloody combat?
It's a bit like a double jump: Silly, yet pivotal to certain tactics.
