I dunno, can I see some ID? Er, okay, seriously...a "Screwjumper" is a renegade intergalactic mercenary ex-mine worker. DEATH IS THEIR BREAD! DANGER IS THEIR BUTTER! They're real tough, hard-nosed sorts, who had spent their lives working in deep, perilous mineshafts on planets like Scruto, Libitino, Floratone and Hecateus -- sort of like a secret society of blue-collar loose cannons from space. Automation at the mines, however, has put the Screwjumpers out of a gig, so they've resorted to mercenaryism to make ends meet and grab a quick adrenaline fix in the process. As fate would have it, the Screwjumpers' primary customers these days are the residents of the planets which are being devastated by the mines in which they used to work -- turns out the folks who actually live there want the mines gone, in a big way. So, irony of ironies, the Screwjumpers have now been hired to destroy the mines they once helped build. Eh, it's a living.
Now, as to the parallel question of WHY they're called "Screwjumpers," that's a little more mundane in origin. Back on Earth, our original design for the game called for the characters to jump down the shafts on these huge, sort of corkscrew-like, structures -- so, yes, they were originally supposed to be jumping down on big screws, hence "Screwjumpers." That lasted for about a week before technical unfeasability put the kibosh on the notion of two zillion rotating corkscrews, but the name still stuck, probably because it sounds kinda dirty.

Screwjumpers? Two zillion rotating corkscrews? Norb! Stop giving away our secrets! Besides everyone knows that Screwjumpers (ex mine-workers) are named as such because of the vast array of screws needed to patch together the mines of the Evil Alien Corporation. Geez..
XBLArcade.com:
LunarDuality summed Screwjumper! up as a modern Paperboy with jetpacks and high explosives but that's based on very limited knowledge of the game. How would you sum it up?

Screwjumper! is a vertical action/racing game which pits the player (a Screwjumper named Skruii, or one of his various associates) against the Evil Alien Corporation known only as the EAC (arent we clever?). Skruii undertakes missions assigned by the Screwjumpers Union. He is tasked with destroying alien mining equipment and architecture while plummeting downward in continual, rapid, free-fall descent. The game is a combination of fast-paced demolition and subterranean skydiving.
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 planets surface.
