Excellent first campaign

A very well designed campaign.

Good design and layout of levels with minimal confusion as to which direction to go. Decent amount of weapon spawns and ammo piles. No visual bugs, no bugs with bots getting stuck or not knowing where to go.

Would definitely recommend.

Short but good.

This is a lot shorter than most campaigns, but makes up for it in the tension department. The layout of the maps is (mostly) well done, and it played quite well. The hordes on the last level might need some slight tweaking for higher difficulties, and I've previously mentioned the issues with ladders, but apart from that it was very well done.

Excellent campaign

This is one of the best recent campaigns I have played.

There seemed to be a good distribution of ammo and other supplies, good balance of the maps with things like hordes and events, etc, and good direction so I never felt lost for very long, and the flow of the map seemed quite natural.

I couldn't find any issues with this campaign that weren't minor issues such as bots not getting into the chopper (Only happened during my first play-through). Or the lighting being a little inconsistent in the warehouse just before - and with - the gun show. It's dark outside and yet there's bright light showing in the top windows.

This is one of those rare campaigns that I went back to play it again the second I was finished.

Pros:

 - Original levels
 - Well balanced
 - Stunning visuals and atmosphere
 - Fantastic voice acting
 - Overall brilliant campaign

Cons:

 - Finale seemed a little short
 - Chapters could have been slightly better balanced for length
 - Minor nav errors for bots in certain places

Conclusion:

One of the most original and visually impressive maps I have played in a long time. I would highly recommend this to everyone.

The setting was beautiful, and felt great just wandering around the field looking at everything.

A couple of the chapters felt a bit long, and ammo piles felt a bit scarce, but I think that's because I like to keep the same weapon instead of having to switch.

The only other improvement I would suggest is to add more things to collect during the finale, possibly 3 in total with a tank in between each one, and tone down the horde a little to balance it out.

Overall, an excellent campaign and a must play for any Left 4 Dead 2 fans.

Pros:

Fairly good balance of weapons and ammo
Nicely spaced attacks

Cons:

Navigation problems with bots
Bots didn't pick up health kits at start of chapter 2
Could use more help in directing people where to go

Conclusion:

A fairly enjoyable campaign if played with friends, but almost impossible to play with bots.

I spent far too long trying to find where to go and walking around the same areas a few times because it all looked the same. Either needs arrows to point people in the right direction, or more distinguishable objects so you can see where you have been before. No points deducted for this issue as I would get lost in a supermarket.

The bots are absolutely useless. I had to restart several times and eventually resorted to sv_cheats 1 just so I could make them keep up. On several occasions they got stuck trying to open a door because they were after a health pack (something they failed to pick up in the safe room) and simply stood still while I moved on trying to find the safe room. Then when a special infected incapped them, the other bots would disappear to help them, only to be incapped or stuck with them as well.

It wasn't just a particular spot in which they got stuck, it happens all the time at several places all over the maps.
