Would be cool if you had parties added and only if you are in a party you can be injured, making it so you can't walk but a friend could drag you to a safehouse or nearby health while you shoot zombies chasing the both of you (or group of you). Also when you are being dragged you drip blood :P
Another idea, how about show med packs on a players back like L4D?
I'd like to help, I can make levels and I'm alright at graphics but I don't have gold.
Example:
rough gun+bag so stfu :P
