Originally, repack was disabled for MWZ, as I didn't like Treyarch's repack system. Now a custom revamp is in place:

These are simple weapon buffs, that act as gun perks (similar to MW3 & IW). Thanks to Killer Potato for coming up with the idea that I'm basing this on.


These don't work the same as Treyarch's alternative ammo types. Instead of being on a cooldown with infinite damage, they offer flat/passive benefits constantly (replacing your normal ammo entirely). So every bullet is always buffed (although the damage benefits do eventually cap out on higher rounds). This idea is based on COD: Ghosts' Extinction mode (it had special ammo as well).


Note that weapons that change in nature when upgraded will no longer be considered as part of their previous weapon category, such as the MP5K (it is treated as a projectile weapon would).

* The AK-74u is classified as an SMG in the mod, but internally is considered part of the rifle category (in real life, it's a carbine). So it gets Explosive Rounds instead of Stun Rounds.
