Ammo crate/box in zombies

[Soldado Suarez]

Is possible can be found or create one mod can spawn an ammo crate/box for zombies if you can use for resupply when you need ammo or do an step for easter egg? PD: is not necessary an ammo crate/box , example buyable max ammo power up is only a metod for get ammo in any moment when you need it
for example ammo machine or mod for bo2
or wall buy max ammo
