Hitman episode 2!!! theres a few teething problems such as the inability to actually activate it right now http://store.steampowered.com/app/236870/HITMAN
Thanks for sharing, timmy010. After going to that page and looking through the comments on the announcement I see someone figured out how to activate it.
Go to https://steamdb.info/app/439890
/ and click on the "free" button at the top-right of the page
Well I'v tried all, but only after actually starting to download Hitman it registered the DLC as activated.
Not sure if I must download it too to be eligible to keep it, it only shows as "Added 01/01/1970"
Also seems there was a previous different second episode that was available couple months ago:
Hitman's second location, Paris, will be free over Christmas and into early next year.
You'll be able to nab the French capital and all of its content from tomorrow, 15th December, until 5th January 2018.
