I am color blind so I am not 100% but I killed a denizen (gun)and I was marlton and he said something I never heard before and I saw a similar shaped cloud like when I unlocked quick revive. The denizen bursts into smoke. It was not that.
However I haven't found anything new that happens. They still take 5 swipes, 2 with knuckle and knives. May not have been denizen related. I feel like I move through the fog easier now though. Maybe it acts as a denizen repellant? Anyone experience something similar?
Worth testing out.
Like I said Im not 100% sure I even got anything, and I'm not the most observant guy. I had the Irn bru and headshot stuff without knowing.
I'm sure you would have found it during the marathon you ran though. I shot the denizen off my friend if that matters at all to you guys.
