Corruption of Champions is what happens when someone's weird D&D campaign gets absolutely soaked in horny and the DM just leans into it. Hard. You start as this fresh faced nobody arriving at the Frost Marches, and within like five minutes you're getting propositioned by a catgirl or fighting off imps that want to do things that are definitely not in the monster manual. The whole setup with the portal and the previous champion from Mareth is there but honestly who cares, you're too busy figuring out if you want to grow a dick or not.
The text is janky in that specific way where you can tell someone was typing one handed. Descriptions of getting absolutely railed by a minotaur will go on for three paragraphs but then a plot point gets resolved in two sentences. There's this one scene early on with a goblin alchemist where you drink something and suddenly your chest is lactating and you've got new equipment downstairs and the game just rolls with it like yeah, that's tuesday. The combat is turn based but it's really just a delivery system for losing your clothes and getting pinned down. I spent way too long in the character creator tweaking proportions and then immediately got turned into a rubbery tentacle monster by a random encounter. The corruption mechanics are everywhere, your body changes, your mind changes, and suddenly you're the one doing the corrupting. There's a whole religion angle with a priestess that starts with confession and ends with things I can't mention in polite company.
The mobile version runs like ass on my phone, constant reloading and the text formatting breaks if you look at it wrong. But then you find a scene with a hellhound that's into petplay and you forget about the crashes. The game doesn't explain half its systems, you just stumble into transformations and realize oh, I'm a futa now, and that opens up entirely new scenes with the centaur blacksmith. It's a mess. It's brilliant. The writing swings between genuinely clever fantasy worldbuilding and the most depraved stuff you've ever read, sometimes in the same dialogue box. Don't play this if you want a coherent RPG experience. Do play it if you want to see how many orifices one character can have.
