Martian Gothic :(P-3): Open World Gameplay (Not Really)

So a nice big open area and a door leading to some tentacle thing that kills you instantly, and me screwing up shooting zombies. It's actually not that big, just very deceptive camera angles. Oh, and we finally get Matlocks door open. She seems to move slower than the rest of the characters when shes the thinnest, yet Karne is the biggest but seems to move the fastest...Weird.
