The Galaxy is a nice, but dangerous place. Just recently you couldn't make a step without running into those fanatical superheroes. As soon as you launch a tiny secret project, hordes of fighters in party-colored tights come out of nowhere and dismantle it into small screws. How unfair!

Now everything is different. The former 'guardians of mankind' have quarreled into pieces, squabbled, and perished into thin air. Good riddance! The horizon is clear, so my time has come! The time of a genius, merciless, and of course unbelievably vile supervillain — actually, at this point, just a villain because there are stupid, spineless, and cowardly other villains who also seek world domination. It's time to put an end to this. This morning I have finally realized that. This galaxy shall be mine!

Supervillain: This Galaxy Is Mine! is an intense card-based strategy game of galactic domination inspired by all sci-fi worlds put together and fueled with frenzied humor. Each player becomes a villain, and you have to overcome other villains and conquer the galaxy! To do this, you use two universal card decks — the domination deck and the minion deck — and in each deck, each card may be used in multiple ways.

You may launch a domination card as an asteroid at another villain. The asteroid would disrupt their plans and possibly kill their minions — and if you charge your asteroid (using minion ops), it can blow up everything! Or you may take a domination card as a project to build. Every project has a minor ability. Upon completion, the project transforms into a secret facility and its major ability comes into effect, providing you with new tactical opportunities.

You also command millions of loyal minions who are not too smart — but they are devoted and diligent! You can use a minion card in two ways: You may put a minion card on your project as a minion mob to build it, or you can discard it as minion ops to perform a special operation. For instance, you may shoot down or charge an asteroid, destroy a mob or a project, increase the building capabilities of your mobs, and so on.

Secret facilities bring you domination points, and a villain who acquires five domination points immediately becomes the supervillain and is proclaimed "Emperor of the Galaxy", winning the game as well.

Team play is possible, and with two copies of the game up to six players can compete at the same time.
