This game is said to be a beginning of a larger, multiplayer post-apocalyptic game project. The game is clearly inspired by Fallout. You set up your warrior and need to defeat other ones on a battle arena. You can purchase different equipment to improve your battle effectiveness. During the battle you'll need to select attacking or defensive skills during your turn and try and end up the opponent's health points before he ends yours.
You are a gladiator. It doesn't matter how your ancestors survived the Apokalyx, the only thing that matters to you now is fighting and winning in the arena for glory, money and freedom!
