Oblivion:Fighter's Stronghold DLC

[Ricochet]

I'm getting back into Oblivion. I have Shivering Isle, KOTN and all the other DLC except Battlehorn. Can someone tell me where I can get this? I don't see it off the official site.

Edit: Ok, I guess I got the name of the DLC and quest mixed up.

 

[Schadenfreude]

I's called Fighter's Stronghold, not Battlehorn Castle.

My understanding is that this was one time a free download. Bethesda now only made it available in the GOTY edition.

It was once a buyable plug-in, but Bethesda have had some issues with it, so it is currently only available bundled with Steam's GOTY.
