It was very cool.
Some things changed in the level:
1) There are divinity statues in Under Watch
2) Greg finally used Eryx to break the "clown wall". There was nothing behind it, BUT he said there will be something...
3) The church scene is entirely different. There are tons of enemies to be killed before the part where you have to get away...
4) A new enemy appears on DmD, it's a blue (almost) Stygian and it's a big one.
5) Enemies on DT made a ton of damage.
6) Greg died at least 5 times.
7) Chainsaw guys were a pain in Greg's ass.
8) He faces Tyrant in the church part.
9) Aquila is amazing as hell, the combos were insane. I'm speechless.
10) I can't wait to see Poison on DMD.
