The Dry Fork Mines closed in 1954 after an explosion ripped through the deep caverns. Hundreds of miners lost their lives in the calamity, their bodies were never recovered. 62 years later, the ML Mining Corporation has plans to reopen the site, hoping to attract jobs and commerce to the now economically depressed area. The team of miners and scientists sent in to assess the safety and viability of the mines reported seeing strange organisms before losing communication topside. Your job is to recover that team – dead or alive.
