Math Combat Challenge is a Math game, and is also a survival game, with some First Person areas and starship areas. The key of the game is solving math problems while trying to survive. Complexity of the math problems are random and can be configured, from simple adds to equations. Some panels require the player to look for the right number across the arena (static panels). Others appear just some seconds with different solutions, where you must shoot the right answer before disappearing (dynamic panels).
The DSS Sandra is the spacecraft in the novel inspired by Math Combat Challenge. Sandra is ordered to go to Titan to investigate the disappearance of a man before the event. This image corresponds to the beginning of the novel, when she flies in the ship that bears his name. It is a special ship, as it operates on an advanced principle developed by herself. Both stories, the novel and the game, run in parallel.
