About this game Read the full description

Fatal Exception is a fast-paced roguelike action game set inside a decaying simulation. Fight through endless waves of corrupted entities, collect powerful upgrades, and push your build to godlike levels — but beware: every boost increases your corruption, making the system fight back harder.

Stack items, evolve your weapons, and experiment with broken combinations as you battle through a world that’s trying to delete you.
