Pros:

+ Extremely fun!
+ Challenging.
+ I like that there were puzzles and mini-games.
+ The side-scroller part was so fun.
+ The finale is really well done.
+ Extremely creative map.
+ I like that the entire time all this crap is going on, you're in a toilet.
+ I also find it quite funny that pretty much any time you fall, you land on, or around a toilet.

Cons:

- There is a part in the third stretch of the map (following the side-scroller part) that is unbeatable. There's a hallway with colors on the ground and you have to step on the correct color or you're squashed.. That part is seemingly impossible. We eventually just skipped it and went to the final leg of the race.
- Minor glitches (like on the swinging platforms in the part following the side-scroller portion of the map).

Conclusion:

I absolutely love this map! It's extremely fun, but definitely not those who become frustrated from dying. It's definitely one of my favorites. I have played it over and over with different friends. It's actually kinda fun (and mean) to play with people who haven't played before and watch them do things wrong and die. Great map.

Pros:

+ Just the fact that it's Heather Mason.
+ Custom animations (Zoey's).
+ Good detail.
+ FPS hands.
+ Facial animations.

Cons:

The only real con I had was the fact that she's so glitchy. When I was using her, every time I was hunted, I couldn't move for a bit after.. It was especially frustrating when playing the Hunter Party mutation.

Conclusion:

This is an amazing skin! I love that someone finally made a good looking Heather skin. The only reason it didn't rate closer to 10 was the fact that it's so glitchy, to the point where it would affect the game play. I didn't mind the other glitches, in fact, I actually found them to be kinda funny.

Pros:

+ Very creative.
+ You have to think about things. It's just just about running and killing zombies.
+ It's interesting how you use the gas cans to get items and whatnot.
+ It's fun when you don't have a team of bots.
+ I like that it's team oriented.
+ The map is well put together looks wise.
+ Challenging.
+ The fire power part. I thought that was neat.

Cons:

- If you're playing alone with the bots it's almost impossible or just boring.
- Certain parts are frustrating for sure.
- During the finale, during my first play through it wasn't made clear to me that the gas can was necessary to finish.
- There were a lot of parts that you and your teammates could fall and hang off the edge, and it was impossible to go back and rescue them 9 times out of 10. It's during the parts where there's only room for one person per platform since there are usually zombies around. (I don't know if I explained that properly lol)

Conclusion:

All in all it was a really fun map. Definitely different which is something I like. I like that it was more like a puzzle and the use of the gas cans. This map is definitely a keeper that I intend to continue to play. Good job! :)

Pros:

+L4D1 survivors.
+CANADA WHUUT. Rep it.
+Really pretty map.
+Really fun to play.
+Detailed.
+ I like how you have the option to go one way or the other in the first part of the campaign.
+The events were good.
+There was a good amount of items and they were well-placed.
+I love the atmosphere.
+The finale was so fun!

Cons:

+Sometimes it's too dark. 

Conclusion:

Really well made. There were no glitches or anything that I noticed. It's like it was made by Valve. This one's a keeper.

Pros:

+Really unique.
+I love that it's like a survival map and a campaign all in one.
+I like how interactive the environment is. You can build or not build basically the entire thing.
+It's so fun to play! I only downloaded it a couple of days ago and I've already played at least 5 times.
+You have the option to have pretty much any weapon you want.
+ Challenging.

Cons:

- Once you build the shelving inside the garage, some of the infected will just stand behind the shelves giggling away (this is mainly with the jockey, and happens to the boomer as well).
- The AI sometimes freeze up. And it would be a lot better if they could grab the items off the research center themselves, once you've unlocked them of course.
- The bots are useless. And once the rocket is done, the bots have a hard time actually going into the rocket. They will stand under unless you push them in.

Conclusion:

This is honestly one of my favorite maps. It's so fun, and really unique, even being so simple. I will definitely make use of this campaign. However, I kind of wish we could have played on the moon. That would have been epic lol.

Pros:

+ Challenging.
+ Nice looking map.
+ I loved the boat event.
+ Really well thought out.
+ Amazing detail. There were so many trees and buildings, and all that good stuff. Great environment.
+ The bridge event was really fun.
+ There was an abundance of items and they were well placed.
+ I thought the train crossing the bridge was a really nice touch.
+ The environment was really interactive, there was breakable stuff, etc.

Cons:

- The helicopter made no sense.
- There was no real story to it. You're simply going from point A to point B.
- Sometimes the bots would glitch and stand in areas, not defending themselves while they were being attacked. This typically happened on the bottom of ladders.
- It was bright, then dark all of a sudden in map 3. It just made it slightly less cohesive.
- There were points where I could shoot the infected/tanks while they were behind metal, unbreakable doors and just kill them without opening the door.
- Purple boxes everywhere throughout the last couple of stages.
- There are some "cracks" in the map.
- Saferooms aren't very cohesive. You'd always end up in a completely different area.
- The gameplay was a little boring at times. It was simply horde after horde.
- I got lost more than usual with this map, and with the many hordes it made it difficult to get back on track.
- The first saferoom only has 2 health kits. 
- No ammo piles in most of the safe rooms.

Conclusion:

Overall it was quite a boring map to play. I feel really bad, because I can tell that you put a lot of effort into it, and it's 1000 times better than anything I could come up with myself. I just feel like there's something missing from this map. It's not unique. It's just another Swamp Fever map. And although the events were all unique, it felt like there was just horde after horde. Good work though. :)

Pros:

+ Just the fact that this is Garrus. Turrians ftw.
+ Detailed skin.
+ Good animations.
+ It looks as if you took him from Mass Effect 2 and placed him in the game as far as looks go.
+ Icon picture.

Cons:

- No first person arms.
- No facial animations.

Conclusion:

Really nice mod, but I do wish the arms were Garrus' instead of Ellis'. I also wish he had facial movements, but I understand that's hard work, and it's not really a huge issue. I still love this mod, really well done! :)

Pros:

+ Jill Valentine! 
+ This mod just makes sense, since Jill is from another zombie game.
+ I've noticed no glitches.
+ Really well done, looks good.
+ Arms are that of Jill's.

Cons:

- I didn't notice any facial animations.
- No name change or avatar.

Conclusion:

Being a Resident Evil fan, this was a really neat mod. I would rate higher if there was a name and avatar change, or maybe just a separate GUI file to download in order to make that happen. Still, a really good skin nonetheless. :)

Pros:

+ Facial animations!!!
+ Really well done.
+ High quality.
+ The cape animation.
+ Arms!
+ Just the fact that it's Lightning! *fangirls*

Cons:

- GUI is a separate download. Would have been better if they were together, but since a GUI is available it's really not a big deal.
- There was this weird glitch where once I was holding a melee weapon.. A quarter of my screen would just be black. It only happened once, but I see in previous reviews that it happens to others as well.

Conclusion:

I am a huge fan of Final Fantasy 13, so I was super psyched that I could have my dear Lightning in this game as well. It's  a really great mod that looks really good. Well made. I absolutely love this skin!

Pros:

+ Hilarious.
+ I love the music that plays when he's attacking. A lovely touch lol.
+ Looks really good.
+ I actually like that it still makes the hunter sound, it adds to the humor in my opinion.

Cons:

I have nothing bad to say really. Although in versus the arms are still that of a hunter's, it's not something that would bother me enough to give you any rating less than perfect.

Conclusion:

I think this mod is amazing. I will now go force all my friends to get it. I love it. It's one of my favourite mods. xD

Pros:

+ Rage face lol.
+ L4D1 characters.
+ Great attention to detail.
+ I loved the finale. It's so fun, and really well done.
+ Items, ammo, guns were well placed.
+ Dialogue & storyline.
+ I like the atmosphere of this campaign.
+ The custom melee weapons.
+ I like how it's challenging.

Cons:

- A bit too dark. Because it was so dark, it was confusing to find my way around at some points (this is a minor issue, since I only had the problem at one point in the map).
- The only bad thing in the finale was how cramped it was. With the tank it was a bit tricky.

Conclusion:

All in all it was a really fun map to play. It's as if the map was made by Valve. I will definitely play this one again.

Pros:

Update Feb 10 2012
- The football tanks were a nice touch.
- Custom melee weapons.
- I noticed that there were no glitches for me.
- It was really neat how there were many different locations. You go from a prison to a football game and everywhere in between. This map is immaculate.
- Attention to detail was really amazing.
- I like that there was a script and a story. There was a reason the survivors were there, and a reason for them getting from point A to point B.
- It was a challenge, for sure. 
- The map flows really well. I didn't have to spend a lot of time searching for where to go, it was clear without being too obvious (I suppose at times it was a tiny confusing the first time, but nothing I have any complaints about).
- Apart from being really nice looking, it was fun.
- Very creative.
- I loved the finale. So much. Especially with the gib fest mutation, because you could just stand there and shoot.
- I LOVE the easter egg. So creative & well done.

Cons:

No huge cons come to mind.

Conclusion:

This has got to be one of my favorite maps. Not only was it really creative, but it was really fun. I would recommend it to anyone. And the easter egg was so good. This is definitely a map you could play through more than once.

Pros:

- Beautiful map, the attention to detail is amazing. Really well done as far as looks are concerned.
- It was huge, with so many places to explore. It felt really real because of that.
- Very realistic. I like that this campaign isn't so linear so to speak. I mean that in the sense that you sometimes go through the back ways of stores, rather than just down a field and road to get to the next destination. It made it much more like a realistic situation in that sense.

Cons:

- For the first two levels, there was very little ammo. And since there was also quite the small amount of weapons, it made it really difficult to get through, then in the last stretch, there was quite a few more ammo piles thankfully.
- Each gun could only be picked up by one person, which kind of went hand in hand with there being no ammo. And not a lot of guns were supplied anyways.
- This may just be the run I did, but apart from 2 pipe bombs, everything was a Molotov. I don't know if it's worth adding, but I'm trying to be detailed.
- The second level, although my favorite, was very long and could be made into two different parts.
- The saferooms were a bit wonky. At the end of the first stretch, you get into a vehicle and that is your saferoom. I forgot to get ammo before the door was closed, and thankfully I did get my health kit. When the second level loaded, we were in some room all of a sudden with no ammo or health kits. That part created a bit of a disconnect I felt.
- Very quiet; very little music and no dialogue.
- When going down ladders, you simply just fall, and in one instance, I actually had to be helped up by a teammate.

Conclusion:

Overall this has got to be one of my favorite campaigns. It's absolutely gorgeous, and it has the potential to become even better. I can't wait to see the finished result. It's one of the most well thought out campaigns I've seen. With some minor fixes it will be perfect. :)
