Oh, there are still a few superhero games.
The problem is: "like this"
Rogue-like: Evolution is something very special in its own way. At least there is one mod that I can warmly recommend.
Rogue-like: Evolution - PrimeMod which expands the game with more options (and fixes a few bugs).
Then there is
The Null Hypothesis. A game where the creators say they were heavily inspired by Rogue-like: Evolution. But even if you can't ignore the similarities, The Null Hypothesis, even though it's still very young, is already something of its own with a constantly growing fan base.
And then there is the classic:
Something Unlimited
In development since 2016, new updates are released regularly and irregularly. At the moment, from what I've read, the game's engine should be changed so that development can progress more easily and quickly.
