While we don't know where the ISO 45 is going to sit in the Modern Warfare 2 and Warzone meta just yet, it has the potential to be a contender, and you'll want to level it up fast just in case it takes over the rankings - so I'm here to break down how to unlock it and how it performs.

There are plenty of weapons to choose from in the game, but the ISO 45 in MW2 and Warzone 2 could make for some interesting loadouts when Season 4 arrives on June 14.

How do you unlock ISO 45?

To unlock the ISO 45 SMG in MW2 and Warzone 2, you'll need to complete Sector D19 of the Season 4 Battle Pass.

Luckily, this section of the reward track is free, so don't worry about having to spend any money if you want to unlock this weapon.

However, keep in mind that if you want to speed up the process, you can purchase BlackCell to get a skip on the Season 4 Battle Pass.

How does the ISO 45 perform in MW2 & Warzone 2?

According to the Call of Duty blog, the ISO 45 is an SMG that specializes in 'room clearing' and dominating enclosed spaces with its 'high fire rate.'

Its 'lightweight design' gives the weapon plenty of mobility and the gun's use of 'higher-calibre rounds makes it a heavy-hitter' at short to mid-range.
