I logged in and moved between the buildings a bit. Interface seemed ok except I had no idea what else to do. I would have to spend some time reading the FAQ and/or wiki for the game. Not sure when I will get to that but hopefully sometime in the next month or so.
I'm doing much of the same. I'm playing a military medic, roaming around aimlessly as well. I've only punched a zombie ONE time. I used up my pistol without hitting anything.
Ah, well... the interface is interesting. It resembles Overkill in some ways. Playing within a web browser is neat, too.
