Pros:

Great level designs.

Nice ending especially the helicopter.

More "realism" levels.

Cons:

Too dark to see everything, and can't figure out where to go next.

Conclusion:

The map was incredibly great and like Dark Hollow said, it's worth a download.

One of my favorite part is the one that fills with barrels. I actually laughing too much 'cause they were too many explosions and me and my friends were arguing about the barrels, but we love that room. It's quite fun!

Pros:

Great re-creation of Silent Hill based from the original SH game.

Great intro with "SILENT HILL" logo.

Nice custom props.

Awesome custom sounds and musics.

Nice and very detailed maps.

Cons:

Hard to find a map.

Getting easily lost if you don't know where to go.

The music at the end should've changed into "Killing Time", rather than "She", but it's okay, I guess.

Conclusion:

If you've played SH before, then you'll probably liked this one, too. One of the best moments in this game is that when you're checking the locker, and if you try to leave, there will be a corpse lying on the ground, and THAT makes me go "Whoaw! What was that?!"

I'd say, this is the best map ever in L4D. And I'd say, I'll give this 100/100, for the best campaign map ever! :D
