For a limited time you can get 3 DLCs for the Free-to-Play game "Friday the 13th Killer Puzzle".
To get them download the base game (only 300mb hard drive space required) and then add the free DLC pack containing the 3 free DLCs to your account (Click install).
Enjoy!
I don't know if they were previously free, but Episodes 2 to 8 DLC are all free at the moment.
