I think one of the coolest things about Hideous Destructor is that despite having a ton of hardcore milsim elements, it's not some greybrown American imperialism simulator
the setting is actually pretty cool (it's Doom), and it's a great excuse to give the player lots of fun scifi tech like remote turrets and energy weapons
which is so much more interesting than playing as an American soldier on yet another generic battlefield and choosing between 17 models of (near-identical) assault rifle
I would really love if there were even one more scifi game with {milsim / tactical shooter} elements, because as far as I can tell Hideous Destructor is one-of-a-kind
although, Receiver 2 is kinda close because it simulates its guns to a ridiculous level of granularity and it takes place in a pretty interesting setting
