Within the limits of each round in consecutive sequence the player and the computer opponent can realize all actions possible within five minutes of real time for each of the ships. During the moment of actions of the chosen active ship all other game units are motionless. Time for decision-making is not limited.
Game locations of real scales are not divided into cells or hexagons. The trajectory of movement of the active ship is determined by laws of physics dirived from speed, size and the shape. Immersion in the game world is carried out by means of two basic key features: historical accuracy of game process and realism.
