it was pretty good. beginning felt a little slow for my taste, but that's only cuz it was the beginning on the game. got better when you had to start fighting. I like how blasted like 3 balls of fire at the corpses to make sure they were dead! plus fire kills bacteria! I also liked how you literally sprinted through the cloud of dust near the beginning. though, maybe some coughs and a little more freaking out would have sold me!
overall, I thought it was pretty good!
