When you activate the key, Steam says "for Beta Test" but the game is full. Depends on the activation options set by the developers. You can ask Rayk Kerstan about this... if you don't know.

He sent me the same kind of key to make my review about your game...
As you can see in the printscreen, it's a full game key:

Hope you understand and be honest.
I never saw a developer entering a giveaway of his own game...
