Subraces?
 

I see all these posts with people talking about playing subraces, yet I don't seem to be able to do so...

Is this some 'secret' unlock or something? Or are they all having to use hacks/mods to be able to do so?

They are an unlock - you have to meet a subrace before you can fly a ship built by it.

The easiest way to unlock some is to play the second challenge sector, I think it's called "End of the World". It's full of subraces. Other subraces are harder to unlock, though... I think I have a post somewhere that discusses them.

Here's a link to the post.

Playing a subrace is an expansion feature btw.

Thanks y'all. That answers my question! FYI, I do indeed have the expansion.

Kudos for the link!

P.S. If any Soldak Folks are reading this, Thank You for such an awesome game! Keep the expansions coming!
