A whole new merc joins the fray along with a trio of weapons...
Version 16.0 release notes:
Those nails on the right hand made me vote "female".
Funny timing, I've been fooling around with a new DB Genome Project signature for the SD forums (still can't have one here ):
You've already mentioned Pirin Medical, Stimtek Medical is the logo on the regular Phoenix's helmet and butt pack, while Hülle is the brand on the Obsidian variant's chest pack.
The only cases whose content can change are the "generic" ones since these "evolve" to include new mercs as they are added: I had a few old generic Elite and Expert cases dropped from Arsenal crates which I had not bothered to open and when I did Turtle and Javelin were part of the possible cards even though they were not released when those cases dropped.
Special event cases are locked to the original content odds, but can be opened at any time.
