Setup: Run a solo mining expedition in Crystalline Caverns. Mobs scale up damage and health when there's other people, and you get all the ammo to yourself. Get the beer buff, and use the driller. In case Driller's weapons get tweaked in the future, I prefer to lower chargeup time, then highest freezing power, lower repressurization delay, and increase pressure gain rate. Try to freeze things as quick as possible since they take 3x damage when frozen, don't release toxic gas when they die, get slowed way down when thawed. When frozen, pull out pistol to kill, melee or drill to kill them and regain health through Vampire perk. Can switch to Better Weight Balance for faster Power Attack if you want.
Try to focus more on the nitra at the start until you have at least 80 for a resupply. There's not much Morkite to mine at the beginning, so I try to run down to the lower levels where the morkite is much more abundant.
When swarm happens, dig into a wall until the drill overheats and call the mule to the back and stand in front of it so you get the 30% damage resistance. Then freeze everything that comes in, throw out a neurotoxin grenade if you start to get overwhelmed or more dangerous bugs appear. When the 2nd wave comes, call a resupply outside of your tunnel entrance, but off to the side so you can still shoot out. If you ever revive yourself with iron will, make sure you gain health via bugs, supply drop, or red sugar. You'll die after 12 seconds if you don't. Outside of the waves, bosco kills most of the bugs for me, and I use the secondary half the time. I've been consistently finishing the missions in about 20-30 mins.
If that doesn't work, equip your favorite class when Today's Special is Dark Morkite Beer on either Crystalline Caverns or Salt Pits low mission length and low cave complexity. Try to mine all the Morkite ASAP to call the drop pod before the 1st wave spawns. Today's beer changes whenever the maps does, and need to reload the lobby.
