Infographic #1 – General overview of the ISO SMG with stats, attachment unlock levels, loadouts and camo requirements

Note – The Camo Challenges for the ISO are the same requirements needed for Handguns, not typically SMG’s, so you will notice you will be leveling up the Camo’s much quicker, than normal.

Recoil Study

Here’s the Recoil study of the ISO Base Ammo with 20 Rounds at 18m. It kicks mostly straight up with a little drift to the Right.

ISO Loadouts

Loadout 1 – Accuracy

Loadout 2 – Balanced Build

Loadout 3 – StealthSetup

Loadout 4 – Mobility Setup

Camouflage Requirements

These are the requirements if you’re looking to max each camo pattern.  Complete all of the following to unlock the Gold Camo for the ISO.

For one reason or another, the Camo Challenge is either bugged, or they purposely made the challenges easier by giving it the same requirements as the Handguns to unlock. 

1. Spray Paint – 250 Kills
2. Woodland – 50 Headshot Kills
3. Digital – 40 Crouching Kills
4. Dragon – 30 Hipfire Kills
5. Splinter – 30 Longshot Kills
6. Topo – 25 Double Kills
7. Tiger – 110 Kills w/ 5 Attachments
8. Stripes – 25 Kills Shortly after Reload
9. Reptile – 75 Kills with 0 Attachments
10. Skulls – 25 Kill 3 Enemies w/o Dying

Keep in mind you can only complete the objective after unlocking the pattern.
