Overpowered is an RPG based on the Ren'py engine. We play as Billy, a guy who still lives with his mom. At the very beginning of the game, Maggie (his mom) buys him his first superpower. Since he needs money, he has no choice but to agree. She buys him the ability of x-ray vision. Before doing so, the nurse who gives him the injection tests his compatibility with this superpower. As it turns out, he is compatible, but something else comes to light.
Unlike most other people who can receive a limited number of these shots, Billy seems to have the unique gift of absorbing them indefinitely. Because of this he can become the most powerful of all other humans, but he must be careful while building up such power. In a world where almost anyone can buy superpowers, anyone can become a potential threat to our protagonist.
