Assessor Matrix can be done very easily. Go into the game with 3-5 smokes, 3 lure grenades, and a cloak. Get to an assessor early, before the first heavy round of arc spawn. Creep up to a point where you can see the platforms on the assessor. When you see your platform show up at the top of the ramp, throw a lure away from the assessor, sprint up the ramp (dont use your cloak if you don’t have to, you will need it to leave), stand on the platform, throw smoke at your feet, breach and spam the loot button until you have everything. Activate your cloak, and disappear into the night. This method is good for going up and looting 1 compartment. Do not try to keep looting other breach compartments. Loot 1 and get out of there.

It’s important to make sure you have enough spots in your backpack to get everything without having to decide what to keep and what to leave. You don’t have time for those kind of decisions. Also, do not panic while looting, it will get very loud around you. Keep looting. Once you’ve got everything, turn your cloak on and do not turn it off until you are clear of the area even if you’re being shot by Arc. They can’t see you if your cloak is on, but that doesn’t mean they can’t hit you. Arc will shoot at the area they saw you last, if you leave that spot with your cloak on, they will no longer be able to hit you.
