The first two downloadable add-ons for fantasy role-playing game The Elder Scrolls 5: Skyrim will be exclusive to the Xbox 360 for 30 days after release, Microsoft has announced.

After that exclusivity window the DLC is free to go live on PC and PlayStation Network.

No further details were offered on the add-ons. The game itself launches in November.

The decision follows similar Xbox 360 windows of exclusivity for Bethesda's Fallout.
