Pros:

-Unique experience.
-Boss fight is exciting and challenging. (It's also survivable if you know how to actually kill it)
-Significantly scary/creepy (random jump scares and such add to this)
-Very detailed.

Cons:

-Needs to be longer/more than one map. Dying leads you to having find all glyphs again, which can take a long time.
-Bots can be a bother sometimes.
-Boss fight needs a little hint, upon my first try the lasers killed me off because I didn't know you were supposed to shoot the large spikes to stop them.

Conclusion:

Overall a very fun and challenging map. Though there are some minor issues, the campaign offers a fun and unique experience, with an exciting boss fight at the end.
