Pros:

Nice level designs
Plenty to explore
Good fun playing through the campaign

Cons:

Too long.
Couldn't find the finale event trigger, had to check here to find how to start it.

Conclusion:

I enjoyed playing this campaign. Nice environments, the outdoor areas especially were lovely. There was a bit of lag in the outdoor areas though, still playable but would be nice if that's fixed in a later version.

Overall a fun campaign! We will be playing it again if we get the time; that's the problem with long maps like this.

Pros:

Detailed environment
Unique setting along the cliff side paths
Nice balance of kits/ammo

Cons:

None

Conclusion:

The best addon campaign I've played. Awesome setting, very detailed. Loved it, thanks!

Pros:

Great new weapons
Awesome scenery and atmosphere
Length of game play was spot-on
L4D1 characters
Finale is a smallish area, fun to get back to if you failed the first time

Cons:

The finale tank spawn during the event is good, but it's too close to the train gate when we try to leave. No space to dodge or fight and someone always dies. I like everyone to live :)

Conclusion:

Love this campaign, it's become my favourite. It's great fun exploring the areas, the details are just so interesting.
