Good but not Perfect.
But overall the game was good and was actually the scariest of 3 (im not so sure but during a part with a zombie on a table being experminted, the electricity went out in the whole block which made it pitch black and i had to walk with zombie flashes in my head to get the flashlights in 3 A.M.)
well even though the game wasn't as good as Half Life 2 and the next episode it was still fun to play while it lasted.
