"On NOV.15, JMR sent official corporate recovery teams onto the Bolero to recover time-devices and extract any survivors. The operation went bad; none of the recovery teams extracted. In order to save their research (if not their employees), JMR elects to declare "open season" starting sDEC.01. They contract freelance crews to recover time-devices inside."
TIME AFTER TIME is a mind-bending time travel adventure for the Mothership Sci-Fi Horror RPG. Survive strange chronologic horrors, solve paradoxical mysteries, and save the station from its own recursive fate—and do it all without accidentally fragging yourself out of both space and time.
The bulk of Time After Time is a tripartite dungeon map: that is, three maps of the same rooms and areas of the space station, but spread across three different points on the timeline. As you move present to past to future, the station changes, and so each of the rooms has three separate keys. Late in the timeline, when explorers and scavengers first arrive, is very dangerous—earlier in the timeline is safer, and holds the keys to many mysteries. But how will you get there? And how will you return?
Also included are a half-dozen key NPCs, twenty-odd time travel devices, basic procedures for dealing with paradoxes and time travel, a few time-based monsters, and some world-shattering ways of ending the Adventure.
