Dread Meta Quest

You're a Gump, an ancient race of monkey-like beings whose numbers have suddenly and mysteriously declined. Your objective is to find the source of the extinction of the Gump and escape terrifying horror levels, ranging from an underground mine infested by an amalgam to a lost ancient civilization guarded by a fellow Gump corrupted by a mysterious force. Will you survive these terrors and discover the truth behind your species' extinction, or will you succumb to the horrors facing your kind?
