Q: Who the heck are the "Race X" in The Expansion game of the first Half-Life, Opposing Force?
Maybe they are the REAL bad guys and they have for leader the mysterious Man G-man?
Good question. I had previously grouped all the known extraterrestrials in the series together under the service - willing or otherwise - of the Combine. It is interesting to see that Race X were more likely not native to the Xen borderworld, as they never established a great presence there. Perhaps they are part of another invading army that was held off by Shepherd closing the portal and ensuring the Combine's unopposed takeover of Earth - they are the
Opposing Force - or maybe they're simply curious travellers. Gearbox wanted the freedom to explore their own alien ideas without interfering with any of the established races and confirmed that, had they continued working on the
Half-Life series, further Race X aliens would be revealed.
Perhaps we'd have learnt more of the Sprite:
