Before you got all excited like I did, Arms Race is a community created contest and while look like there is a prize, I don't think the selected items will be featured inside the game officially.

I admit I got a bit excited with the possibility of seeing new weapons, but unless said weapons actually change gameplay like Kritzkrieg and the Flare Gun did, it's hard to get overly excited.

Well, we still have (theorically) the Pyro update thing… right?
