The "Revive Partner" action needs a little reworking. Whenever I try to revive Hank when he's down, it doesn't allow me to do it (even though there are no zombies around). So for all of you frustrated out there, here's my tip: First, kill all nearby zombies. Then save. Now, when you restart the game, your partner should still be up and alive and you're not angry and pissed off.
