Alien Crush is officially the hottest thing ever, even though we're not entirely keen on the new 3D look -- and even though we prefer Devil's Crush to Alien Crush. Among the many reasons it's super hot (reason the first: DUDE ALIEN CRUSH RETURNS) are the new ball upgrades. Reverse Ball allows you to instantly send the ball back the way it was moving. Split Ball enables multiball on the field. Boost Ball boosts the speed of the ball.
Strangely, these new "Action Balls" will be available as DLC. We don't know if they're otherwise unlockable, or if they'll be paid DLC or just time-released. They aren't the only Crush DLC, either -- new stages for the game's Story Mode will be available as downloads.
