Dunno, but I've got it, too.

+1 I got it as well. I hope I can keep it :p

Wow, nice

I got too!

Yes, I didnt own it and now in the DLC on properties it says Dawnguard.

same, might be a glitch, i'm not sure if steam will honour it or not

All 107 of my Steam friends own Dawnguard now, but only 69 of them own Skyrim! xD

It's downloading now. woow big suprise

I don't even own Skyrim and it says i own Dawnguard.

It dont appear in account history, so im afraid I/we will lose it :(

edit: just going to try it :p

Wow, nice catch, I got it too! Now I just need Dragonborn...

same here, just got dawnguard

This is what I get for buying Le edition! >:(
Edit: Bethesda has committed crimes against humanity, I mean think of all the poor traders who work hard selling that dlc, now all their stock is worthless and they can't feed their families and will go hungry.
Mankind may soon be extinct because someone thought it was funny to give away free stuff without having people pay for it, this is going to cause chaos and lead to the end of civilization as we know it!

I got it too, but I got no Skyrim.

Same here i have skyrim and 0 dlc. But it's downloading atm.

Yay all my friend and their friend friends have dawnguard now!

Yes, now i have Dawnguard but i dont have skyrim xD

Most likely a mistake. Someone probably fat-fingered an AppID they were supposed to make free.

I just found this screenshot in the Skyrim forums, it doesnt show as already owned when you add it to your cart, like other items would.

inb4, Bethesda say....this is suppose to be a steam glitch, but we are doing a goodwill, buy skyrim now and get to keep ur dawnguard or we take it back....

enhanced steam shows it in GREEN (which means I own it) ... I don't have Skyrim basegame though..

awesome of them

i have it 2. i do not have skyrim

Wow I have it too, nice!

seems too good to be true, its not like its a 2$ dlc, its 20 big boys
