How to Unlock Nail Gun in Cold War and Warzone
Unlocking the Nail Gun is fairly straightforward. Players will have two options to claim this new Special Weapon: play through multiplayer or directly in Zombies. Here’s how each option works:
In multiplayer, players can just grind Special Weapons. This can be attained by just playing multiplayer modes that allow you to collect the most amount of kills in a short amount of time — grinding.
Players will require five eliminations in total with Special Weapons in 15 different completed matches.
As for Zombies, players can play Outbreak with Special Weapons as the main source for eliminating their foes.
