The Ship at the Edge of Time (Ultimate Ending)

A derelict ship floats empty in space, harboring a dark secret. You are Andon Mercer, space marine. Along with your co-pilot Serena, the two of you must board the Dauntless and solve the strange mystery of her frozen, haunted corridors. Yet those corridors might not be so empty. Not when the source of the derelict ship's troubles unexpectedly returns. Can you find out what happened to the ship and its crew? Or will an unknown enemy — alien in origin — return to claim its prize?
