The game turns the tables on more tradition sh'mups, giving players the opportunity to build up an army of ships and toss out as many devastating projectiles as possible. I.e. you're dishing out the bullet-storm rather than avoiding it.
And according to Co-Optimus, the game's looking to make the jump to Sony's Playstation Network. It'll be interesting to see whether the game retains its XBOX Live Indie Games $1 price-tag.
