Like A Well-Oiled Machine

Complete a Hazard Level 4 mission with nobody dying and no resupplies ordered - the Haz 4 version of Bring Your A-Game. A clean, ammo-disciplined Haz 4 run: no deaths, never call a resupply. Bring ammo-efficient mods and play conservatively; a short mission type you can control (Mining Expedition) is easiest. Solo removes the risk of a teammate dying.
