Dead Quiet
Complete a map without ever triggering a horde from Reekers, Birds, Snitches, or alarms.
Can be done on Recruit difficulty in Act 1-1 ('Resurgence'). Having Karlee on your team helps highlight flocks of birds, Sleepers, and alarm locks on doors early through walls.

Intentionally lower your health to below 20% (red screen edges) and throw a Smoke Grenade right at your feet while Ridden are nearby.

The Path To Glory
Complete a map in Trial of the Worm with a total modifier of at least x20.
Before starting the first mission, adjust the Corruption Modifiers so the multiplier gauge shows at least x20. Reaching just the very first saferoom objective under these conditions is enough.
Constant Vigilance
Kill all variants of the Sentinel.
Sentinels are mutated cyst structures in Act 6. Destroy all variants, such as the Swarm, Miasma, and Acid Sentinels, during a regular playthrough.
Hard-Boiled
Defeat The Harbinger without using the LAW.

LAW and Hors D'oeuvres
Blow up a Food Item with the LAW.
Look for a consumable food item like corned beef or cereal bars on the ground and fire a LAW rocket directly at it from a safe distance.
