==Call of Duty: Mobile==
The ISO returns in Call of Duty: Mobile. It was added in August 2024 as part of the Season 7: Eternal Ghost update.
===Multiplayer===
The ISO is a more traditional submachine gun, with a high fire rate, medium damage, and higher-than-average mobility. It does 25-23-17-15.
Recoil is low for an SMG, going up and drifting to the right, similarly to the BP50.
In terms of mobility, the base ISO has several of the same stats of the QQ9, including movement speed, sprint speed, ADS speed.
The ISO's attachments are very similar to the attachments available for the CX-9, including an integrally suppressed barrel, a 30-round magazine, and a 50-round drum. Interestingly, the 30-round magazine and 50-round drum have the same reload penalty, meaning that the only difference is in overall movement speed.
The ISO is very interesting in how it matches another submachine gun - the QQ9 - in many statistics. In direct comparison, the ISO exchanges up-close damage for longer overall range and better recoil control. However, when attachments come into play, the QQ9 can beat out the ISO in terms of ADS Speed when both are configured for maximum range.
The ISO overall serves as an alternative QQ9, with worse close-up damage in exchange for better DPS over range.
