[FREE] [STEAM] (Beta) Metal Revolution {You may keep the game} [currently out of Stock]

According to a redditor, who claims to be a Mod from the Server:

As a mod in the channel i can say that some of the info here is wrong.

The beta key will stick with you for the game, and the game stays in your steam library in case another beta happens or the game goes to lauch
