chautemoc: You can't respec companions unfortunately. You just start them at level 1 so you get a little more freedom with how they're built, but it's not a true respec.
Reever: So you can't change their attributes?
No. You just influence whatever feats and talents have.
@blotunga Hold your horses, mate. Wasteland 2 GOTY is near ( free upgrade for backers and early adopters, just like Harebrained did for Shadowrun). GOTY comes with quite a few new things, so no point in restarting again when that is releaed.
And for the impatient people, Obsidian said that they will try to bring the beta-patches on GOG, but they can't guarantee they will manage. Let the Steam crowd beta-test, i'll be happy with the final patch.
