Screwjumper! is a 2007 arcade game developed by Frozen Codebase, LLC for Xbox 360, centered on high-speed vertical descent through a subterranean alien mining operation. Players take the role of a Screwjumper tasked with dismantling enemy infrastructure by freefalling through it — the faster the descent, the greater the destructive force inflicted on structures below. Dynamite is available to handle hazards and priority targets along the way. Each stage culminates in destroying the mine's core, after which the player must escape using a jetpack. The core loop revolves around managing velocity and explosives to maximize damage while navigating the chaos of the underground environment, blending momentum-based destruction with moment-to-moment combat against alien mining defenses.
