Pros:

-Awesome skin
-No bugs with the textures

Cons:

-Many animations are bugged (further elaborated in the conclusion)
-Still Louis' voice (I know it'll be hard to put Lee's actual voice into the game, but it's not too much of a big deal because Louis sounds somewhat like Lee anyway)

Conclusion:

It's a great skin, with the exception of some animation bugs. The animations for healing and pretty much anything where you must hold E make Lee look like Jesus on the cross. From a third-person perspective, sometimes Lee slides along the ground like a statue. Also, when I was using a chainsaw as Lee, whenever I went to attack with it, the game put me into third-person view, which was annoying.

Pros:

-Great level design
-Loved being in the city

Cons:

-My mate and I found the entire campaign a little boring
-I felt the campaign was a little too linear, with the exception of one or two places
-Had trouble getting the bots into a safe room at the end of one of the chapters
-Fails to capture the feel of Japan when not in the city

Conclusion:

If you like a straightforward campaign where you basically do the same thing in each chapter, this is the campaign for you. I prefer campaigns with riddles and backtracking (e.g. Silent Hill L4D2), so this wasn't really my thing, but I have to give you some points for the effort you and your team put into this campaign.

Pros:

-Gives the medkits a more weathered look, being an apocalypse and everything
-Textures are fine, there are no bugs

Cons:

-None that I can see

Conclusion:

Nothing really special, it's more for people who are sick of the old medkits or just don't like them.

Pros:

-Great fun
-TNT crates have a countdown timer and explode
-Nitro crates explode
-Bounce boxes work fine
-Ooga Booga boxes actually play the Oooga Booga sound when destroyed
-Traps/hazards were fun to encounter
-Familiar music and locations
-Decent length
-Players return to a kind of hub at the start of each chapter, allowing for planning and resupply
-Loved the hidden weapons under the crates

Cons:

-Bosses could be a little more interesting to defeat

POSSIBLE SPOILERS BELOW

-The finale doesn't really make sense because you blow up the ship while you are still on it

Conclusion:

Great fun campaign whether or not you're a fan of the Crash series. Much more fun with humans, but bots seem to do okay as far as I could see.

Pros:

-Great tech tree
-Great defense-building mechanics
-Loved holding off hordes while trying to assemble a rocket
-Great game to play with friends

Cons:

-No clear indication of where you can build things until you get close to them, but I suppose that's part of the fun
-Bots won't take weapons from the tech tree
-Bots refuse to enter the rocket once it's complete, so they must be killed in order to escape

Conclusion:

This map is better played with a full team of humans, because the bots have trouble doing some important things. It's a good map whether you're looking for a quick, casual play session or a long, intense battle against hordes (depending on difficulty).

Pros:

-Cool introduction
-Great maps, really well done
-Campaign was of a good length, took me and a mate an hour to complete
-You managed to fit the voice acting with what was happening on screen, which is a first for me in custom campaigns
-It was really fun to play

Cons:

-One thing I noticed was that there were too many med-packs. I'm not sure if this changes depending on difficulty or if it just seems like a large amount because I just played the Silent Hill campaign where it had like one in each level.

Conclusion:

This campaign was great fun, please make heaps more in the future.
