Is there downloadable content for fallout 3 on the ps3

On the third Wednesday of every other month, you may download -- for free -- new perks, NPCs, the ability to level up to 30 (gaining perks all along the way), and a multiplayer patch. Downloading this content requires that you have already installed another operating system (i.e. Linux or Unix) through the "Install Other OS" option in the PS3's menu. Checking for this content at a time other than the third Wednesday of every other month will result in a null-return search.
