It's the year 2257.
When a mysterious beacon is discovered broadcasting from Jupiter's moon, Europa, ten rangers are dispatched to investigate. What they found was an abandoned terraforming colony. And that mysterious beacon? That was meant to be a warning. For something terrifying was buried just below Europa's icy surface. Something that mankind was never meant to find.
PFC Samantha Bauer, (a cadet thrust into the assignment against her will), finds herself unable to return home. While trying to survive the frigid, inhospitable environment of Europa, she gets sucked into a battle between the crew, battles horrifying creatures, stumbles upon secrets left behind by the station's previous inhabitants, and all while trying to stop an ancient evil from escaping Jupiter's moon. Will she survive long enough to accomplish any of their goals?
