Interplanetary is a turn-based strategic artillery game on a cosmic scale. Develop your home planet and use massive barrages to wage war on a galactic battlefield, turn by turn.
It's an arms race with each planet developing increasingly powerful weapons. Gigantic railgun batteries are the backbone of any interplanetary arsenal, but the cunning use of missiles and precision lasers may just hold the key to victory. Strategic build patterns, upgrades and defense structures might keep your vital installations standing long enough to give you an edge, but it's only a matter of time until all but one will fall.
Sometimes, your greatest foe is the planetary system itself! Don't let the unpredictable gravitational changes get the better of you—observe your surroundings, use them to your advantage, and blast your enemies back to the Stone Age!
Interplanetary: Enhanced Edition, is a revised version of the original Interplanetary.
The no longer supported original is included in the Enhanced Edition for free, for the purposes of historical preservation and (hopefully) flattering comparison.

Graphics: AMD HD 7700 Series, 1 GB VRAM or Nvidia/Intel equivalent

Directx: Version 10
