Yes Sir!
I picked up Sniper Elite2 2 weeks ago when it was free for 3 days on Steam.Red Orchestra 2 along with the expansion Rising Storm - both SP and MP - I picked them up on Steam for free back in May when Tripwire Interactive offered them for free for 5 days. As well Origin offered BF3 for free for 4 days at the beginning of the month so I picked it up for my son Nikolai as I already own the game but he is not allowed to play my account. I also picked up Dead Space for free on Origin 6 weeks ago. Iron Front Lib 1944 Lite( low textures only MP no SP campaign) is still available and if you are interested I can give you the download link. As well I got the game Lost Alpha, a stand alone game based on the famous Stalker series of game, based on the very popular game Stalker the Shadow of Chernobyl made by a Ukrainian company...I also have the link if you want.
My advice: always cour Steam Origin and Ubiplay and Gog.com because they always have nice classics for free or on offer or even future game betas on offer!
