To be honest, we know next to nothing about any of these games. We dug up an interview with the Screwjumper developers on XBLArcade. They describe the game as a "vertical action/racing game" which tasks the player "with destroying alien mining equipment and architecture while plummeting downward in continual, rapid, free-fall descent." They go on to say, "The objective of the game is to maximize score by crashing into and dynamiting as many alien structures as possible on the way down the mineshaft, then to initiate a detonation and race back to safety on the planet's surface." Well, if it's coming out in November, we don't have to wait too long to find out what that means -- thank goodness for XBLA demos.
