The ISO 45 is one of the brand new weapons that arrived in Season 4 of Call of Duty: Warzone, Modern Warfare 2, and DMZ. It’s a compact submachine gun that has one of the highest fire rate stats in its class, making it an absolutely lethal choice at close range. As such, many players might be interested in how they can unlock the new SMG.
While there is certainly a more traditional way of unlocking the ISO 45, some players are curious if they are able to accomplish the goal in DMZ. In the past, DMZ has been home to several new weapons that players are able to extract using a variety of methods. Sometimes you have to kill a boss while other times a weapon is waiting for you in a specific spot on a map.
Below, I will explain how it’s possible to unlock the ISO 45 both inside and outside of DMZ.
Getting the ISO 45 in DMZ
For starters, the easiest way to currently unlock the DMZ is by simply leveling up your Season 4 Battle Pass. The ISO 45 is available on Sector D19 in the Battle Pass as a free tier, meaning players don’t have to pay any money to unlock it. They simply need to use enough Battle Pass Tokens, which are earned by playing the game, to unlock the ISO 45’s tier.
Aside from that, players can also take advantage of a hidden method in DMZ. However, this will require a friend or willing participant that already has the ISO 45 unlocked. If you head into DMZ with that person, they need to have the ISO 45 equipped as they primary or secondary weapon on their loadout. Once you are in a match together, that person needs to drop the ISO 45 on the ground, allowing you to pick it up and add it to your inventory.
From there, all you need to do is find an extraction point with the ISO 45 still in hand and you will have it unlocked in DMZ, multiplayer, and battle royale. It remains to be seen whether or not the ISO 45 can also be acquired by other means in DMZ, such as killing a certain boss. If any other methods are discovered, we will update this article.
