I'd say the ability to create barricades would be my #1 thing I'd like to see. The ability to make a small fort (walls at least) to keep an small area safe or create a safehouse would be phenomenal, or perhaps a barricade across an alley or street. #2: Remember the "Gang Wars" bit of the story? What about that, but with zombies? Kill so many zombies, the section is (reasonably) safe and it'll come under attack sometime in the future. But certain sections are impossible to make safe, like the more populous areas of the cities. #3: Ammo-scavenging, maybe just re-spawning weapons/ammo in certain areas (like a safehouse) to keep it simple. #4: How about actual seats in the back of pickup trucks so someone can drive, and others can shoot? Or with the flatbed to create a mobile base?
