If you like your strategy games seasoned with a bit of tower defense action, you'll be glad to hear that Sang-Froid: Tales of Werewolves is now free on Steam. It released back in 2013 to some fairly good reviews, and if you're wondering why exactly its free right now I am afraid I have absolutely no idea. There is nothing on Steam, the developers don't seem to be releasing a new game, and the official website is currently down, so consider this one a bit of a mystery!
For those of you wondering what Sang-Froid is even all about, allow me to show you the original trailer. It should give you a good idea of both the story and the general gameplay, but if you need a little bit more information before diving in you will find a lengthy gameplay trailer by heading over here. But for now here's the original trailer, and have fun with the werewolves!
