This is Pyro GX as seen in D1 and D2.
What was released some time ago was Pyro GL, along with Magnum AHT and Phoenix, all from D3. While GL resembles GX, they're noticeably different.
It would be great if we could get an Expediator into FS. Perhaps along with a few robot models and original designs, a Descent 3 mod could be made for FS, focused on space combat. Could be interesting to try and fit it both into FS and Red Faction storylines (D3 mentions a rebellion on Mars, and IIRC, not many things prohibit these three series from being in the same universe).
