Your hyperdrive gate can be kept off the game board until you are ready to place it into the game, and can be placed anywhere on the game board using one of your turns. You can also remove it from the game board using one of your turns. The hyper drive gate will allow your communication core to move any distance in any single direction after it passes through the hyperdrive gate; when used, the hyperdrive gate must be in the next square space in any direction of the communication core, and the communication core will continue to travel in that direction any distance. You can pass through as many of any blocker asteroids after passing through the hyperdrive gate. You can also use your opponents' hyperdrive gate as the same function to travel, though you cannot control your opponents' hyperdrive gate movement. If your hyperdrive gate is next to a space of an opponents' asteroid you can swap spaces with that asteroid or send that asteroid back to your opponents' hand off board. The hyperdrive gate can move one space when it's your turn.
