I felt like this level is more challenging and not as friendly when it comes to co-op. You've got enemies that doesn't stop chasing you no matter where you go unless you hide (in the older levels, they give up when you go through a window or another area), the stagger time for enemies are much shorter here when you throw an item, and the hiding spots are very few and can only hold one person at a time (which is why it isn't game-friendly for co-op -- only 1 person can hide in a box/closet within an area, while the others have to run for their lives and suffer injury). And LOL on 19:52 and 22:21 - 22:28.
