It's easy to see this is made by someone who knows what they're doing in Hammer.
Very well-detailed, immersive, realistic environments.
Interesting idea with the church.
Good fun to play.
Cons:
Fairly short.
I cannot play the last level as it crashes on me, although I suspect this is Valve's doing since the same has happened on the final Sacrifice level ever since it has existed.
Conclusion:
A fun campaign to play through; a shame I can't get to the end, but what I have played through is very promising. Possibly a tad generic and a little short, but not at all bad.
Pros:
