Are you on the hunt for all the Call of Duty: Black Ops Cold War evidence locations? Then you've landed on the right page. In the Call of Duty: Black Ops Cold War campaign, there are a set of side missions called Operation Chaos and Operation Red Circus that see you playing as Mason, as he and Woods hunt down specific targets to weaken the Perseus network.
You can start these missions at any point, but to do them properly and get the best ending, you’re going to need to collect evidence to get the context necessary to understand and complete these missions. Sure, you can go ahead and do the missions without all the evidence but, to do it right, we advise making sure you have all the evidence before you begin.
Fortunately, collecting the evidence is easy thanks to this handy guide we've put together, which reveals the location of each piece of evidence that is spread throughout the campaign in various locations. Below, we've rounded up every piece of evidence in Black Ops Cold War, to help you get closer to cracking the code. It's worth noting, though, that evidence spawn locations may differ from player to player, but we've highlighted when this is the case and if the evidence isn't in the exact area we mention then it'll likely be close by.
Ready to hunt down Perseus, detective? Here’s how to find every piece of evidence in the Call of Duty: Black Ops Cold War campaign.
Call of Duty: Black Ops Cold War evidence locations
Below, you'll find the location of each piece of evidence from Operation Chaos and Operation Red Circus in the Call of Duty: Black Ops Cold War campaign.
Nowhere Left to Run evidence location
In Nowhere Left to Run, when you’re interrogating Qasim at the end, you need to ask him “Who is Arash meeting with”, when given a list of dialogue options, and then capture him when you trap him on the Amsterdam rooftop.
Brick in the Wall evidence locations
In Brick in the Wall, you have to accept the optional mission from Greta in the bar to rescue or silence the informant. Then down where the informant is being held, grab the Operation Chaos evidence on the desk where the guard was sat.
The second piece of evidence in this mission is right at the end when you’re infiltrating Kraus’s house. Once inside, don’t tranquilize his wife, but sneak upstairs and enter the master bedroom. The evidence is in the bedside table drawer.
Redlight, Greenlight evidence locations
In Redlight, Greenlight, when you’re traveling down the fabricated Main Street in the Soviet base, head into the building on the right with the sign that says ‘60 Min Photo’ and move upstairs. Kill the general in the far corner and then take a picture of the map on the wall to get this piece of evidence. There are six pieces of evidence in this mission but you don’t need them all for the clue — just keep an eye out for the ‘In Objective Area’ markers when you’re exploring.
Echoes of a Cold War evidence location
In Echoes of A Cold War, once you take out the snipers outside the satellite building and drop inside, this cassette is on a table in the middle of the room, near to a body with a crossbow bolt which you can examine.
Desperate Measures evidence location
In Desperate Measures, following the briefing with Gorbachev, head downstairs and disable the cameras. Then you’ll be tasked with finding a bunker key. Ignore this main objective for now and look around the rooms. The evidence can spawn in a variety of locations, but I found mine in the Data Entry room near the top right, on the table in the back office. You need to pick a lock quickly and then take down the guard and hide the body to secure it, as it’s in a restricted area.
With that, you will have every piece of important evidence in Call of Duty Black Ops Cold War, enough to access the two campaign side missions and complete their objectives without anything going wrong.
