Yes, the title is a subtle reference to "Breakin' 2 : Electric Boogaloo"
I'm now the oldest fart in this group.

"What is this glorious metallic update!" you may ask yourself, or your friends, or me, but you shouldn't ask me, because I'll say something witty and build up your dream that maybe a new weapon, map, or even a class was added.

No, it's just hats. Not just hats though, robotic versions of the hats that have been sitting around the Mann Co. store for months collecting dust.

Valve wants you money, but they don't want to work for it anymore.

I already have all the cosmetic items I could ever want and then some... and if I want one of these robo-hats, I'll just wait for them to appear on the Mann Co. store, ironically, the same place where the hats they copy are stored.

Maybe they'll add an option to "Mechanize" the hat your looking at, although I doubt TF2 to be THAT clever until a community member comes up with the idea...

...hey guys, I have a community idea I want to submit to Valve!

-Happy MVPin' gentlemen. Perhaps you can do so in some "robo-style".

There's a new MvM map, robot to kill, and a new comic. Also some new Smissmas items, Adult Swim themed hats and accesories, and a few new weapons.

Merry Smissmas!

Starting today you can excercise your right to hate robots, and destroy them.

This cheese doesn't seem so mysterious until you realize it's full of bullet holes. Somebody got to this cheese before it could talk.
