A decent metric to judge when a game has truly hit the mainstream is when Steam's active sex game scene sees fit to make a parody. Congrats Helldivers 2, meet SEXDIVERS ????, an "intense survival shooter" releasing sometime in 2025. Yes, the emoji is in the title—I didn't know you could do that on Steam either.
While I wouldn't say anything about Sexdivers looks fun or particularly good, I have to commend developer Octo Games for competently recreating Helldivers 2's look in its action scenes.
