My bro: Justin (best bud)
Weapon: Scattershot (Halo 4)
Food: Hamburgers, macaroni and cheese.
Assuming that I have unlimited ammo for my weapon and these are slow-zombies, I should survive for quite sometime. My friend has the Zombie Survival Guide and likes reading/playing/watching zombie stuff, so if there's anyone I would want with me, it's him.
However, we might get fat from eating nothing but burgers and mac' & cheese...
