The listing, Interplanetary Enhanced Edition steam key has ended.
Interplanetary is a strategic turn-based artillery game on a cosmic scale. Develop your home planet and use massive barrages to wage war on a turn-by-turn galactic battlefield.
It's a war race in which each planet develops increasingly powerful weapons. Massive artillery batteries are the backbone of any interplanetary arsenal, but the clever use of missiles and precision lasers could be the key to victory. Strategic building patterns, upgrades, and defensive structures can keep your facilities vital enough to give you an edge, but it's only a matter of time before they all fall—except one.
Sometimes your biggest enemy is the entire planetary system! Don't let unpredictable gravitational changes get you: observe your surroundings, use it to your advantage and send your enemies back to the Stone Age!
