Pros:

-Gameplay that has been offered like none other.
-Well optimized, absolutely no major lags of any sort.
-Perfect Length (Medium-Long)
-Intro is very welcoming. When you see it, you know the campaign is already good at the first second.
-Gives a very good idea on what The Nether and other ideas would like as I actually never been to those type of areas before.
-Very few AI problems. The problems seen does not pose a major problem towards gameplay.
-Acceptable difficulty and horde events are just about at the right amount.
-Crafting? Lets building something good. (Adds a good and even an important part to this campaign.)
-Environment, and visuals. They are worth every second of exploring to look at the details.

Cons:

-Got lost at some areas, no points taken off as the visuals have made it up.
-Tier 2's could have started a bit earlier for "Chapter 2: The Lake Ravine". No points taken off as it is only my preference and I'm not going to change your ways of how items/weapons spawn.
-Witch placements. Although that is actually the games fault and I happened to be in bad luck against them for this game. No points taken off.

Conclusion:

If there's an option to pick a "Campaign of the Year", it is this one!

Excellent gameplay, visuals, and environment. This campaign really kept the Minecraft theme true to it's potential.

Although played in my own SourceMod server, I can see absolutely no problems on being able to play this campaign on a non-modded server. Whether or not you have actually played Minecraft before, I highly recommend stopping on by and grabbing this campaign at this very moment before you miss something! If you have enjoyed this campaign, it is something that is worth keeping.

A complete 10 received from me. This is a memory that is worth having. Well done.

Pros:

Excellent for those new and old alike that wants to wants to learn how to kill a witch by themselves.
Instructions are easy and quick to follow.
Videos included along with the instructions.
Well optimized, I received no lag of any kind during single player gameplay.
Custom music is well picked.

All of these methods work in L4D2.

Cons:

Was missing a method or 2 that I know, one of my most favorite ways to kill a witch.
Not really a con but I wished that there was a 2nd map that tests everything that you have learned during the 1st map.

Conclusion:

Easily one of the best instruction training maps that was created for L4D1.
A must have and deserves a score of 100.

Pros:

Literally the only SPAS-12 shotgun replacement that I see that has the unfolded stock, well done.
The pump at the ending for the SPAS-12 reload is great.
Basically everything else I saw.

Cons:

None.

Conclusion:

Autoshotguns reanimated at their finest, what else do you need?

Pros:

Reload animation is amazing.
View angle is near-perfect, I think it's a bit too close in my opinion.

Cons:

Hell no, you win it all.

Conclusion:

Oh man, I have been using the Hunting Rifle a lot lately, should I choose the Hunting Rifle or Military Sniper rifle?

You have my other 4 points.
