Monday Night Combat - steam

[Untouch]

Ok well I was doing my usual thing and was about to play some Black Ops when I saw a new game in my games list.
Monday Night Combat. It says I have 3 days left to install it.
I never bought the game so how did that happen?
It just randomly appeared in my list.
Anyone know?

Edit:::::::::::::::::::::::::::::
I just noticed anyone can play it free this weekend.

Yeah Steam likes to frequently have such promos which are great in my opinion as they let you try out the full game and determine if it's really worth the $ or not.

It's a shame Xbox Live/PSN does not do this...
