Corruption is a fast-paced 3D beat-em-up game that takes place in the far future, on a planet comprised of what looks like black sludge. The game follows a deformed creature that can absorb his opponents to take a new form and a new type of battle style for every new enemy he kills. The game has 10 set chapters, each with one miniboss and chapter boss, but the game becomes more free roam once the campaign is completed.
While there isn't much of a story told throughout the game, there are hidden labs in each chapter that tell a loose story, all of how the planet was turned into a living hellhole and how most of the monsters in this game were once animals, but were horribly deformed after sludge began to cover the planet. So, while the story is still there, it's completely optional and more of a secret.
