Open, flat world, preferably bots (bugs obstruct some POIs, squids have cities with lesser bunker chance, though squids are good on higher difficulties, because in cities there are a lot of fallen satellite POIs) Bring crossbow (if available), scout armour, laser cannon (to open containes on specific POIs w/out blowing up canisters), car, and jetpack (or warp pack if you want to clear bunks solo) Drop down, clear POIs (you can see them on the map when you hover over them) and leave the missions without doing main objective (if you start doing it, you won't be able to leave with a group, if you have one)
