With Season 4 adding even more weapons to add to your collection, you’re likely wanting to know how to unlock the ISO 45 in Modern Warfare 2, a fierce new SMG. The MW2 ISO 45 is one of the three new weapons you can get in Season 4, and a throwback to an old favorite.

Call of Duty Modern Warfare 2 is consistently upping the ante with new weapons, maps, and more each season. With this being one of the Modern Warfare 2 Season 4 guns and weapons you can earn, it could very well enter the meta and be one of the top choices this season. But, first you need to get it.

How to unlock the ISO 45 in Modern Warfare 2

You can unlock the ISO 45 in Modern Warfare 2 by reaching battle pass Sector D19 in Season 4. You do not need to spend any COD Points as this sector is free.

With Sector D19 being the penultimate Sector, it will take you quite some time to get the ISO 45. As always though, you can speed the process up by claiming only the Sectors required to reach D19, as some can be avoided until after you’ve unlocked the Season 4 weapons. And, if you really can’t wait to unlock the ISO 45, then head into Ground War or Invasion to earn Battle Pass Tokens as fast as possible.

The ISO 45 is a high rate of fire SMG, supported by the stopping power of .45 Auto rounds. With SMGs always being a popular weapon class in MW2, and the ISO 45 having a competitive fire rate and heavy stopping power, the ISO 45 could jump to the top of many player’s lists. What’s more, it’s also a throwback to Modern Warfare (2019), which featured the ISO submachine gun.
