Hunt: Showdown, Crytek's game of competitive supernatural big game hunting, is free to play for the weekend on Steam—and the weekend has already begun. 

It hasn't actually begun, obviously, this is only Thursday, but the Hunt: Showdown freebie is live now. Just pop over to the Steam page, click "Play Game" button, and... play the game. You've got until 10 am PT/1 pm ET on August 13 to squeeze in as much monster-hunting as you can, and collect some of the half-dozen new Steam trading cards, if that's your thing.
