"Uber key -> Steam key" is possibile?

Hello,
I bought the game on kickstarter ($ 20 version), now I see that is regular in my uber store.

is possible to convert the key of the game from uber store in a key for steam?

Thank you.

$20 tier doesn't include Beta access, it's retail key.
When game released you'll able to convert it to Steam key.

thanks much for the info!

On a related note, I did the $40 backer tier, so I was wondering if I can get the beta on steam instead of the regular one.

If you've got beta access, on your key page there is an option to convert it to Steam. Beware that it is one-time and you won't be able to download the game itself anymore, only via steam.

This is not true, you can still play and update the game using the launcher.

Yep, but first you need activate key in Steam and link your Steam and UberNet accounts. Linking happen automatically when you login with your credentials though Steam.

You can also link it manually here:
