Killing Floor 3sends you back to the Army Depot in the Containment Measures mission, just after you obtained a few samples from this area. Completing this mission can be a bit trickier than others, since you must interact with certain elements in two objectives.

Your last visit to the R&D Lab yielded some slightly creepy results after scanning the samples. While you can’t undo the outbreak, you can do some damage control. Here’s what you need to do for this mission inKilling Floor 3.

Containment Measures mission guide in Killing Floor 3

Containment Measures has two main objectives:burn tainted corpses and scan shipping containers.They’re spread out over different areas in the close-quarters Army Depot, so knowing how to move through this zone is key.

Where to find tainted corpses in Containment Measures in Killing Floor 3

Here are the corpses we found during our run of Containment Measures. We located four tainted corpses taking the path inAbsolute Massacre, which leads you through the train wreckage and deeper into the main building. Locations may vary depending on runs and spawn points, but you can get more than five of them in a run.

If the helicopter drops you off in the garage, you can find a tainted corpse just to your right and another one past the broken blast door that connects to the warehouse up ahead.Light up at least one of them, then take the ramp or the stairs into the train pit.Cross over and you have four tainted corpses in a somewhat straight line.

One is by the tunnel, near a blast door marked with a D, to the right of the regular spawn. Another is on your left, near a broken wall with an explosive barrel on it. Find one more in the train’s wreckage and look for the last one by an armor box nearby.

Burning five corpses and surviving the way points you to the next main objective, which is further inside the warehouse and requires you to scan three different containers.

Where to scan shipping containers in the Main Building Interior

The next step requires you to scan three shipping containers, which are easier to find when you’re not being chased by hordes of the clinically undead. The first two are close to each other, but the third takes a bit of backtracking.

Grab the first two as you’re heading into the main building interior, then hunt the last one when you’re free to go to the inspection room. You can climb the second-floor platform with a red light, emerge on top, and work your way down.
