Castle Conquest is a virtual pilot game, which requires the players to don headsets in order to play. The game can be played cooperatively or competitively, with at least three players able to play at a time. If a player's ship is destroyed, or even voluntarily, the player can move around on a smaller hover board. It also appears to have online connectivity, with "Destructo" communicating and playing with Manic from long distance.[1]
