Pros:

-I love Minecraft, free points there...
-Keeps alot of the Minecraft fee
-I loved how you had to craft items to continue on.
-Great Opening

Cons:

-The snow and rain
-This is just a nitpick but i didn't like the lighting, i like Minecrafts classic shading than the more realistic shading and reminds me that i'm not playing Minecraft
-Unoriginal, Minecraft maps have been done before.
-So apparently turning lava into obsidian angers Zombies now?

Conclusion:

This is definitely the best Minecraft-based map for Left 4 dead 2, i reccomend you download this and all the addons listed, however the lighting may turn off some and some of the area's are lackluster and uninspired. I have to give this an 8.5 out of 10.

Pros:

-Perfect Atmosphere
-Not too hard but not too easy

Cons:

-Ridiculously long
-Revolves around simply finding keys
-Every map feels the same, except for the last few.
-Repetitive
-Weird camera angles for certain events, except for the dead Siam
-This can also result in unfair kills, however this is unlikely.

Conclusion:

This campaign can either be your friend or your enemy. Its a fun map but after playing it, you realize its just collecting key after key and killing millions of special infected. While its strong in certain area's, the rest is just boring.

Pros:

-Great sights
-Not too long, not too short
-The audio files were used well, i love the Boat scenario.
-Best startup music
-No bot problems!
-The Foam FInger
-Custom skinned tank
-Portal 2 easter egg!

Cons:

-Occasional NPC problems, but nothing game-changing.

Conclusion:

This campaign is fantastic.  I enjoyed playing it from beginning to end, it introduces so many new things that gives it a unique feeling, this is worthy of being an official Campagin.

Pros:

-Adds a far more horrifying feel to the tank.
-Seems like a better theme to the infected.

Cons:

-Could scare people with mental issues in dark area's
-Doesn't clash with certain campaigns

Conclusion:

This is a skin that has the right to replace the orignal pink one, and is well worth a download.
