Just a few suggestions before I post. And none need take effect now, if at all. I only ask they be considered. (I'm having fun with the rp right now, don't worry.)
Just to keep things fair, if GM likes them, we should probably vote so nobody quits!)
If we're to really make this survival, perhaps we should be keeping tabs on our stock of ammunition? All each person needs to come up with, is how many (realistically) rounds of ammunition their character is carrying. Or GM could alot each person X amount of mags for each weapon. And we use that from now on.
I'd also suggest we keep tabs on how many zombies are in... X area. We could begin this now, or after they've entered into a safe area.
I'd also like a roll for ...Things such as combat (I don't mean shooting one or two zombies, or sneaking up on one or two.) and, uh... Crazy stunts. We could let the player roll themself for general things. Let GM roll for anything they deem major. All ya gotta do to know, is... If you think it's major, just ask GM. she's around erryday. ;)
I feel these little bits of detail would really be fun. It mixes it up a little and I think interesting. Even you don't know what's gonna happen next... The only person who really knows what will happen in the end though... Will be our devious GM. Also as a note, I'd be happy to assist with these duties.
Edit: I'll be posting soon!
Second edit!: doing all this would also more than likely help post length too. Perhaps someone fails what they were gonna do? What are they gonna do now? Numbers of zombies are good as well. You know exactly how many zombies there are if you wish to describe them and flesh out your post a little. And what specific actions your character has to do to do them. (@.@ to do to do...)
