Developed by Team Jolly Roger for Windows, Linux and Mac, Interplanetary is a hard science fiction turn-based strategy artillery game where players wage wars by developing their home planets and firing their interplanetary barrages through the planetary system. The game combines base building with classic artillery game mechanics. The tricky part is firing your cannons through the planetary system, avoiding other planets' gravitation or using it to your advantage.
