Lost my preorder key?

[naturon]

There are no retail copies available at all for pre-orders, if you mean boxed versions of the game.

It will be digital download only for all pre-orders. All pre-orders placed in the frictional games store get access to windows, mac and linux + steam activation key, all which will be available at shelf.frictionalgames.com.

Oh okay, but I'm still not sure whether or not stand-alone digital copies are available. Is Steam the only medium this game is being released on digitally?
