Corpoct Gives the main character the opportunity to take part in grandiose cosmic battles. For this purpose, he can, out of his choice, make a fleet of ships. It includes a wide variety of vehicles – heavy, well -armed cruisers and battleships, light and maneuverable fighters. At the same time, the main character cannot give orders to combat units. Also, he cannot make their settings. Movement in the game arena occurs during battles. At this time, the ships decide independently by which type of weapons to use, and what purpose to fire. Before the start of the battle, the gamer has the opportunity to place elements exclusively on the field.

All locations and spaceships in Corpoct are randomly selected. During the battle, the protagonist affects its ending through the use of cards. These items can be called analogues of magic spells. With the help of cards, missile strikes are made for a certain purpose, or the power of the ally of the aircraft is restored. From time to time, the user can use 3 cards from the deck. He gets them in his arms, after which he plays to get Mana.

In order to carefully study future actions, the protagonist can use the function of temporary stopping the battle. According to the plot, the main character is an employee of a large corporation. Then he independently engaged in the organization of the expedition in the vastness of the Galaxy. He has the opportunity to recruit positive and negative characters, find and store resources, build shuttles and modernize his armed forces.
