KILLING ZOMBIES

Each survivor in your group can handle a certain number of zombies. Assign weapons to boost these numbers.

A survivor is an approximate match for however many zombies he/she can handle. Example odds ore 50/50 a survivor that handle 10 zombies can do so against 10 or so zombies.

Overkill is underrated, especially when unused ammo is brought back and can be used later.

But try to leave the heavy weapons for when you have lots of ammo, they can do alot but certainly cost more to use than smaller items. Plus the extra noise will lure in zombies from all around.
