Warhammer 40,000: Darktide

On the mission select screen, Uprising difficulty will be the missions that have two bars on them. Completing a mission on 2 bars or more will give you credit toward this Achievement. You can also keep track of how many of each mission you have completed by cycling through your Penance book to the Missions tab. Use it if you are having trouble knowing which mission you're still missing. There's more than one mission per mission type, so don't worry if the mission description I give isn't the same thing listed on the mission select screen, just check the icon and mission type listed.

The 7 mission types are as follows:
Assassination - A crosshair icon, get to an area and eliminate a named boss. Example; redirect the train carrying the Captain with the force field generator on him.

Disruption - An X icon, get to an area and stop an enemy operation in progress. Example; the enemy is brewing new pathogens in four tanks in one area, get there and blow them up.

Espionage - An eye icon, get to an area and retrieve important information. Example; fight your way to the archives full of scrolls and scan the computers for data.

Investigation - A radar icon, get to an area and scan the environment for something important. Example; a new plague variant has been detected, scan the area and follow it to the source.

Raid - A dagger icon pointing up, get to an area and liberate supplies from the enemy. Example; get to the landing pad and carry the containers of special ammo to the drop off location.

Repair - A wrench icon, get to an area and fix a critical system that is designated non-expendable. Example; get to the power station and use the cryonic rods to fix it.

Strike - An arrow icon pointed down, get to an area and restore functionality to a something the enemy has shut down or sabotaged. Example; get to the forge and restore the smelting generators by destroying the Chaos infestation.

Good hunting Operatives, may the Emperor guide you on your mission.
