Task Force Doppelgänger [X-COM/Battletech]

The Year is 2025. The war started 10 years ago and has been grinding on since. And now Vahlen built a "Star Gate", explore, make new friends, steal everything thats not nailed down and try to ignore earths looming fall while you race the clock on the other side of the gate into a new universe. Apparently they got giant stompy robots over here.
