Everybody is gone. The base is empty and the whole crew has disappeared without a trace. You are stuck in a parallel dimension research base with your team, the place echoes with emptiness.

Now you can only count on each other to figure out how to fix what is broken and to get home before the energy cells of the P.O.R.T.A.L. are fully discharged and the self-destruction program launches.
