Hi guys. So, I just found my old Steam account information and logged in for the first time in several years. Because of that gap in usage I am quite unfamiliar with the site and their usual services.

The client is asking me to download a game called "Awesomenauts" with a note by it saying that I have '6 days left'. As far as I know, I do not own this game, and while it looks okay, I am unsure why I am being prompted to install it. Could this be a game they are offering for free? Does Steam even do that?? Or is it some kind of trial offer or perhaps even a gift?

I apologize if this is a silly question. I looked for a place to ask this on the Steam site, but all the links seem to lead to the product information page, not to a forum or discussion page.
