25 6 6Actions Report Solution In order to upgrade skills (or anything in your load out, for that matter) you need “raw Aetherium crystals”. In order to get these, you need to reach round milestones (survive to 10/15/etc...). I’m sure there’s other ways, like the trial rewards and such, but this is the most consistent way to get them. You get one for each milestone per game.The first upgrade is 1 Crystal, with the second being 2 and the 3rd being 3, respectively. Achievement should pop after upgrading a skill (in my case I upgraded my Juggernog perk) to level 3. If you downvote, please let me know what I can do to fix the guide!

You have to be connected to the servers to unlock the achievements. It’s weird that DOA achievements are working for you but the other ones aren’t.Posted by Divine Fear on 05 Dec 20 at 19:06 Yeah thanks that was it I didn’t have xbox live gold you have to be online now it works thanks againPosted by Robscout on 06 Dec 20 at 13:09 I’m doing this during the zombies free access week and nothing is unlocking. Upgraded the Juggernog to Tier III and all. Definitely connected online and linked up to my Activision account. Guess you have to own the full game.Posted by Burty Jr on 18 Jan 21 at 19:49 Leave a comment
