OK, a few things, 1 where is the reload key? why can't I manually reload my guns during a lull in the swarm, 2 why can't I affect my barricades in game? I built a bench wall on either side of my character and I can't get out...which worked perfectly until the final zombie in a level gets stuck somewhere and I can't get out to find him...HELL I can't even destroy my own barrier wtf!? 3 STAR CUZ OTHERWISE IS FUN!
