Questions on new final update stuff

So what are the three new stations again? I remember the chemical lab and the drill, but what was the last one? Also, what ammo can the Exp. AI76 take? Can it take literally all of the types or just normal ammo and not .50, 40mm, or HEDP? And why do the devs recommend we get Russian Dolls before the update drops?

So far all we know is that Napalm cannot be used with the EXP AK, if there is any other restrictions is unknown as of now.

This is so you have the full idea of the story before hand.

Got it. Now figuring out the stations is next.
