"Solo Dice & Card game. The player must defend and build up his Space colony." The game uses a custom card deck containing four types of cards: Events, Invaders, Defenders, and Structures. Each Structure card is rated for power use, number of defender cards supported, and Mega-credits generated. Defender and Invader cards have Force values. Events represent good and bad happenings in the game. If the player's Base is destroyed, the game ends and the player loses. Otherwise the player attempts to have as many Mega-credits as possible once the last card has been drawn from the deck.
