Incredibly short and okay at best. The story ends at the moment where it seemed to start building up towards something interesting.

While the game is derivative in its design and played it incredibly safe by opting to not introduce anything new in terms of enemies or weapons, the atmosphere in places felt better than the base game. Having more environments where it was darker and you had to have the flashlight always on felt like a nice change, at least in my opinion.

You don't get the crowbar until you're pretty close to the end of the game, and combined with the limited ammo you get in most chapters, it was pretty noticeable the devs wanted you to over rely on the gravity gun.
