Insurance returns
Insure what you can replace from the mail. Do not insure junk you will not pick up again.
Fee versus risk sits in additional guides.
Extract trains
Trains are loud. Arrive early and watch the approach, or take a quieter extract with less loot.
Do not sit in the open car if you hear another squad sprinting.
Mobile-to-PC habits
Mouse peeks are faster than a thumb. More game information helps you stop over-aiming every corner.
Use the same map knowledge. Change only the fight speed.
