The latest version. I was able to use a bug I found to my advantage in the game. If you crouch the whole way to your objectives, Siren Head wont be able to kill you. Which means you can basically have him as your handbag puppy. It was funny the whole time. But it's really scary other than that bug. He comes back crawling immediately after you shoot him. no time for you to run! You did good on the game, but why are the system requirements so high?
