Please enter only if you are OK with deleting the giveaway in case the key doesn't work. I had an invalid key in a bundle I bought recently, and while I got a working replacement, that might be a bit more problematic when making giveaways from unused keys of older bundles. I'm 99% sure it works though.

Since this is a DLC, please check your library before entering since SteamGifts can't detect DLCs. Good luck and have fun.
