I never played the game but watched some trailers and gameplay videos. I’m 99% certain that Helldivers 2 is following the Starship Troopers formula and purely making fun of patrionism, propaganda, war, the military, military personnel, “freedom”, heroism, politics and military advertisements and turning that into a game. There’s just so many obvious signs, it seems impossible to miss. In other words, it is a political game. Or maybe I just really don’t get either of the two.
I’ve tried it for a few hours (reached level 5 quests so far). I’d say it’s not bad. It’s reasonably fun with quite an interesting setting and story, though some gameplay parts could certainly be better. (eg. inventory&item management, skill and enemy diversity)
