How to remove Altitude from my Library with no install?

[ARK]

Last night I checked out the video for Altitude and decided I didn't want it. I went in to play Portal and Altitude was in my library listing along with Portal. Its not installed but why is it there and how do I get rid of it? I'm pretty sure I didn't click anything to add it in.

Games that are free for a certain period of time will always appear in your library. When the deal is over, you will no longer be able to play Altitude and it will be removed from your library unless you decide to purchase it.

This is not to be confused with something like Portal, in which it is free for download only for a certain period of time, but you will still be able to play it after it is no longer available for free.

Aiq's information is correct. If you don't want to see the title in your list at all while the offer is on, just change the drop-down selection from All Games or Mac Games to Installed.

It's free to play over the weekend, unless you buy it after the weekend it'll be removed from your library. I rather like free weekends.
