@@user-nw2lb8ii7sYou can't it was a limited time bundle skin. Only way to get it now is to buy a blueshark from the market that has the skin equipped. I've seen a couple in the market here and there
IMHO, Argonaut is better for teamplay. Blue Shark is better for solo gameplay. But instead of BS it's better to buy Gorshkov right now. Cheaper and same dps, maybe even better. At least subs cares more about Gorshkov.
