Back in 2007, No Gravity -- spaceship shooter -- popped up on a number of PSPs as a homebrew title, but tomorrow, it'll be available for all on the PlayStation Network. No Gravity: The Plague of Mind will pack five spaceships with different specs (speed, shields, etc.), a few unlockables, and 31 different missions for you to conquer, according to developer Anozor's PlayStation Blog post. You'll need to speed through the galaxy blasting foes to come out on top of the game's six worlds.
