Interplanetary - is a turn-based strategy game set in a "hard" science-fiction setting. The player must develop their own planets and take part in non-military interplanetary artillery battles.
An arms race on an interplanetary scale has unfolded, and each planet develops its own powerful weapons. Huge railgun batteries are the main power of any arsenal, but skillful use of rockets and precision lasers can be the key to victory. Strategic placement of defensive structures and planning upgrades will help your forces hold out in epic battles.
Sometimes the planetary system itself will become your friend. Do not underestimate the gravitational pull of planets, so always pay enough attention to your surroundings so you can use it to your advantage and send opponents back to the Stone Age.
