I've been able to download the most recent version of Ravenfield for free on multiple sites. I think you need to check it out
you can always buy the game, test it for a bit and refund it on steam if you don't like it. if you own the game for less than 14 days, and played less than 2 hours they will refund your game. don't pirate it, because that's mad disrespectful to the dev who worked hard on the game.
Well, you can always refund it if you get it on steam... (within 2 hours of play time or 14 days, if under 2 hours played).
