Solar is a universe sandbox/simulation title that has players wandering space as stars, planets, asteroids and black holes. Judging by thie clip, it's an atmospheric game in which players interact with other celestial bodies, pulling other planets and asteroids into their orbit, and even waging war with rival solar systems.

According to our sister site IndieGames.com, players can foster intelligent lifeforms on your planet's surface that will build defensive turrets and spaceships that can fight against other planets. When they run into other civilizations, they can destroy the other group by smashing into their home planet.

You can already download the Solar "prototype" for just 80 Points on Xbox Live, but indie developer Murudai is working on a "remake/upgrade" titled Solar 2 for Xbox and PC, which is what you see in the IGF 2011 submission video above.
