[FREE][GOG] Slain: Back From Hell

There is a giveaway by the game's publisher Digerati Games. You need to subscribe to their mailing list and they will then send you a GOG key for the game. Since I'm not allowed to post the link by SG rules, if you want it, go to the mydealz.de site, search for the game's name and then click on the green "Zum Deal" button. The key will expire in 2 weeks, if left unused.

For reference, Slain: Back From Hell on GOG.

Digerati Games:
As a "Welcome Present" I am giving you a free copy of our best selling game Slain.
Why?
Well, I want you to have a chance to play the types of games that Digerati publishes.
We distribute free keys every day at 7AM PST time because so many people are taking us up on this offer. Thank you for your patience.
