Dark and Darker's leveling system is quite confusing to understand, especially if you want to maximize the various characters and classes you have, as it never seems to end.

No matter how much you level up, it never seems to stop. The original beta for Dark and Darker in 2022, before it was pulled from Steam, limited players to level 30, but now it goes much further.
There doesn't seem to be a maximum level in Dark and Darker, but leveling up doesn't really do much for your character because of how the game works. I've seen players go past level 99, which I originally thought was the max level, but the leveling requirement gets harder the higher you go.
Once you reach level 15, you unlock all the perks, skills, and slots you need to equip. Your stats don’t grow as you level up, since all of your stats come from the gear you’re wearing, and there really isn’t much reason to level up other than to gloat and give yourself an ego boost.
