In a test I used all weapons except the explosive bullets, at that save state I seem to not yet have collected the blueprint for that. In a much later save I actually did use the explosive bullets, and that should have unlocked Versatile.

AFAICT... you have to use all weapons in one mission or even partial mission to unlock it. Using those weapons *any* time in the game does not seem to be tracked.

It should be noted I am going for "Clean Hands" in my first run, thus I don't use weapons at all (other than animals).
