Here's an experiment with adding damage numbers to SS2. Hey, Prey did it!
https://www.youtube.com/watch?v=-GHISGkGy6cCan optionally combine consecutive damage received within a certain time window into a single popup, which is enabled in the above video.
Not sure if the numbers are big enough. Since they're HUD overlays, the size of the numbers is dependent on the HUD scale. Making them bigger would require a custom font, though it would be a font with only ten characters, so not much work to make.
One issue is that the numbers render behind the health bars, but that's just how custom overlays work, nothing we can do about it.
