Pros:

Great atmosphere

Almost feels official

The darkness!

Cons:

A few bugs

Conclusion:

Not much to add except that this is a unique campaign. It's so dark, but fully playable. You seem aware of the existing bugs so hopefully those get cleaned up. I hope you can work on another campaign down the road as this one is quite enjoyable. A few fixes and it could be perfect. Great job.

Pros:

Well constructed levels

Great atmosphere

Attention to detail

Fun for single player action or with friends

More entertaining than the 2004 remake

Seems to be bug-free

Cons:

None

Conclusion:

This is one of the very best add-on campaigns available. I tend to play custom campaigns more than the official ones these days and this is one that I go back to time and time again. Thank you for creating it.
