I daydream almost daily of turning myself into a projectile and rocketing myself across the sky. With a Half-Life gauss cannon in my hand, I think I could fire myself from my window to any destination within town.
Interplanetary does one better. It's a strategy game in which you use the gravitational pull of planets in order to slingshot projectiles across the solar system, so that they smash against the fragile planets and moons of your opponent. It looks a little like DEFCON by way of Universe Sandbox. Since I wrote about it last month, the game has found its way on to Steam Greenlight, and there's a new trailer below.
This is what space combat will really look like. Not photon torpedoes or space lasers, but heaps of rock and metal fired at supersonic speeds across the cosmos or between spaceships. Maybe there's one such missile floating towards us right now, fired by some unseen civilization.
Probably not though. Probably you'll have to play this game instead. Go vote for it on Steam Greenlight.
