This post from Johan Pilestedt, creative director at Arrowhead Studios, gives a sales estimate for HELLDIVERS 2, the PC and PlayStation first-person shooter homage to Starship Troopers. Despite some issues that are still being worked through, word is the game has sold "around" a million units since its launch last Thursday (thanks Reddit). In a previous post, Johan addresses the suggestion that the game is pay to win:
I'm partial but we really applied ourselves to not make it p2w even though items are functionally different. The only item that's p2w is the revolver - which will win you any "cool gun" competition. Only (minor) problem is that it's not that good. 🤷
