WELL VERY SOON YOU CAN!

It's game that you can call an ASTEROID in as a KINETIC BOMBARDMENT... TO DESTROY A PLANET!
With up to 10 players doing an all out war! In the Early Access Alpha!
It's supposedly taking the best from Supreme Commander and Total Annihilation.
Fuck you budget... that game DESERVES MY MONEY!
