I'll try to explain quickly. Basically, you post an action, for example: I look out the door, to see what's there. Then me, the mod of this game, tells you the result, for example: You see a giant swarm of zombies. Then you post another action, etc. Also, it's best when doing actions to say something like, I try to shoot the zombie in the head, vs. I shoot the zombie in the head, because I have to determine what will happen and if you succeed. Doing actions relevant to skills will increase those skills, for example shooting will make you better at the small arms skill. Now I have to go, so I'll start this round up in a few hours.
