I’ll leave this open, because I’m only posting 100% confirmed things in the mega-thread, as well as clues given by official DB sources.
As for what I think of it…
The limited edition event Loadout Cards will be available for 30 days following the release of the update and can be obtained in three ways.
CW Equipment Cases give a 0.3% chance of scoring a Containment War Loadout Card
CW Elite Cases have a 10% chance
Purchase a bundle of 10 Elite Cases for a bonus CW Event Case that guarantees a Containment War Loadout Card.
10% chance for one of them from a CW elite case? Yeeeeeeeeeea- No. Probably not a good idea to jump the gun on it, but the cases don’t excite me at all. I’m quite content being hyped over the new content and merc - cases with RNG like that seem like a waste of time.
