Call of Duty: Black Ops Cold War Zombies - 100% Challenges & All 6 Seasons Complete
Here is every single calling card and challenge complete in Call of Duty: Black Ops Cold War Zombies! Upon completing all the normal zombie challenges you will be rewarded the "Zombies 100 Percenter" Calling Card depicting a samurai with a frame of bone arms grabbing eachother. There are 250 zombies challenges (251 including the 100%er challenge). Along with the normal zombie challenges are 6 seasons of 21 challenges where starting at 0 you unlocked a challenge every 10 levels until they were all unlocked at level 190 and then a 21st mastery calling card in each season for collecting all 20 calling cards of that specific season. This video shows all 6 seasons of challenges completed and all their mastery calling card rewards as well. I also show off all the Dark Ops challenges completed except for the "King of Silverbacks" for collecting 1 billion points in Dead Ops which I will probably get eventually (im about halfway there...)

Call of Duty: Black Ops Cold War - Zombies - Mauer Der Toten - Klaus Stops Train & Uranium Building Steps (Gameplay Guide)
0:01 - Finish last of the 3 cannister filled up at the green boxes
0:15 - Hit switch in Switch Control Room and get an upgraded Klaus (only one upgrade is fine) to stand on the tracks by calling him in up and down the tracks. Once the train comes...
0:53 - Klaus stops the train
1:00 - Pick up the Warhead and Ricos ID Keycard. The warhead can be taken back to the cannisters. The Keycard will be used to initiate the computer by Klaus
1:44 - Interact with the computer by Klaus a few times until the screen turns red. Then interact with it again to call in a Megaton and 2 red Mimics.
2:41 - Kill the 2 red Mimics first and then kill the Megaton last as a timer will start once the first split Megaton Blaster dies. They will each drop a Uranium so its a good idea to lead them to the work benches so you can quickly build them on the next step. There are two workbenches under tents in Easter Berlin Streets and Checkpoint Charlie.
3:18 - Pick Up 1st Uranium
3:25 - Build 1st Uranium [in video Im at workbench at Checkpoint Charlie]
3:44 - Grocery Store Uranium Zipline Location
4:13 - Pick up 2nd Uranium
4:20 - Build 2nd Uranium [in video Im at workbench at Checkpoint Charlie]
4:44 - Korber Sign Uranium Zipline Location
5:05 - Pick up 1st Finished Uranium
5:38 - Deposit 1st Finished Uranium
5:33 - REPEAT the Uranium Steps again the exact same way (except this time the Mimics and Megaton will spawn on top of one of the buildings) and when you deposit the 2nd Finished Uranium, the bossfight will start. Drop it next to the cannisters so you can get prepared. You will need at least Full Armor, Death Machine and double PAPd CRBR-5 Wonder Weapon and all perks except Tombstone and Mule Kick is not completely necessary.
Hope you enjoyed this guide, more coming soon :) CW Zombies - Mauer Der Toten - Klaus Stops Train & Uranium Building Steps (Gameplay Guide)](https://i.ytimg.com/vi/fDgT38_DN3k/mqdefault.jpg)
