Edit4* Ok so it seems i didn't give much detail to the scenario;ammo,zombie type,surroundings etc. [b]*Remember this is just my idea of zombies* [/b] There would be a lack of ammo as every gun shop and army supply crate has been scavenged,the zombies are [b]slow,rotting corpses[/b] meaning if you're on a roof you're pretty safe although you need to take trips for food water etc. Meaning you need a gun...well the all mighty God Deej has sent down a beacon where you can grab [b]any exotic[/b]from destiny and have it fully functioning in real life.I would choose ice breaker because of the infinite ammo and explosion to groups of zambiz that would be a sight to remember. Certain perks involving getting "kills" would surely not work as zambiz are dead...or are they?
