Pros:

- There were so many extra nooks and crannies which makes me very happy. Hell, I didn't even get to all of them because I was horde-paranoid. 

- Just overall very well-designed and interesting. Map 1 is a conventional campaign chapter, with Map 2 being a holdout in a non-linear small town section and Map 3 being a finale with a cool main base. And I loved a couple of the undergound/sewer sections as well as the supply shop in Chapter 1 with the eerily funny posters.

- I really have to show my appreciation for Chapter 2 again. It's really really awesome and open.

Cons:

- Some AI quirks during the very end of the finale where they would fall into the deep water and foolishly try to revive eachother. 

- Arguably.. a teeeeency bit too short.

Conclusion:

If it were a bit longer, this would be among my favorite campaigns like Deathcraft II, No Mercy and Dead Air. One or two tiny little other problems as well hardly hold this back from being great and one of the best campaigns I've played. 

I'll probably be having my buds download this!

Pros:

- Open nature environments look pretty cool, occasionally beautiful. We need more campaigns with this stuff.

- A couple neat, surprise Witch encounters.

Cons:

- Started to feel a bit padded out towards the end.

- "Panic" Events and (especially) the finale are both far too easy. There were literally no zombies at all during the climb to the helicopter and when there finally were some, we were already too far ahead of them.

- Grey, pale blue/green environments got really old by the end.

- Rather than adding to the experience, the voice acting and mid-air text purely distract (although, the zombie joke at the end made me chuckle). The acting isn't... "bad", but it still got a little obnoxious by the end.

Conclusion:

This campaign has potential because it was starting to get really really good. But then after the heli leaves you behind for the dumbest freaking reason during chapter 3 (?), it starts going downhill and eventually screams of lazy design. Underwhelming "panic" events/finales, more and MORE grey walls, etc.

And some more emphasis on story-telling could've really helped the voice acting be half-enjoyable. The campaign, as is, being advertised as "story-oriented" is misleading as hell. Some unappealing, generic 16-21 year old voice  occasionally telling you where to go and a last-minute (and also underwhelming) "Hmm... I wonder what's in the box?"  bit don't really seem like valiant efforts to create a story here. 

Pros:

- Not too many L4D campaigns are as brightly colored as this. A welcome change of pace.

- Nice sense of humor with the ads.

- Forklift area was a great place for some tense horde/Tank battles, despite the somewhat stupid idea of waiting for the forklift to very VERY slowly move out of our way.

- Perfect length. You'd think with only 3 chapters, it'd be much shorter than usual, but it's actually about as long as most of the official campaigns. 

Cons:

- It's very hard to do cold, sterile, bright future structures and cities without making them look straight bland. And this campaign doesn't exactly steer too far from that problem. 1 or 2 times, you'll find yourself looking at the landscape, but likely that second time is to look at almost the exact same thing you just saw. The design is kind of a mixed bag, with only the occasionally neat layout.

- The finale was far too easy and short. On top of that, the ending was just... bleh. And I was looking forward to seeing it after seeing a couple "It made me laugh." comments. It only made me raise an eyebrow.

- One platforming section, the AI isn't too equipped to handle. You might be standing in a single spot for up to 2-5 minutes waiting for them to finally get it.

Conclusion:

What ultimately saves this from being a somewhat low score is it's bright aesthetics. Once again, I've hardly ever seen a campaign so bright and if my sockets could smile, they would. An uninteresting gritty environment is far worse than an uninteresting bright environment, to put it one way.

Out of the 4 or 5 custom campaigns I've played thus far, though, this has to be the worst. It is worth a download, but if you're pressed for space or aren't too interested in near-future/future environments, I'd say stay clear. Oh, well, unless you're in the mood for some ultra bright colors.

Pros:

- Just about a straight port of some of the later sections of HL2. For some, this will be seen as lazy. But, to me, because of the already high quality of those said sections and plus reasons below, it was for the better.

- Has one of those "little bit of everything" vibes to it. There's always a new, effectively used climatic event coming up. Mad props especially to the fire/smoking building section which was far better than what Valve did in any of their own campaigns.

- Decent use of music.

- Lots of little extra nooks to search through. 

Cons:

- I was personally hoping to see a few of the earlier sections featured as those are some of my favorites and would also work great with L4D. Even though the way this is structured makes sense for the sake of further preserving the HL2 design, still.

Conclusion:

Overall incredibly solid.

Even though I preferred the fact that it was a straight port of HL2's later parts, it probably could've used a tad more creativity. Or maybe a few extra HL2 characters/sound clips to round out the obvious attempt to be super faithful to game.

What makes this an 8.5, though, is it's variety. It never once got boring. 

If you love HL2, I guarantee you will at least really like this campaign.

Pros:

- Like Pajama said below me, it's incredibly faithful to the Minecraft design. With imported mechanics from Minecraft, appropriately reskinned Special Infected (Creepers as Boomers is just too perfect), overall feel of the map is just very very Minecraft-y. 

- If I were paying for this, I wouldn't have felt cheated at all. This campaign is LOOOONG! Arguably, maybe too long. But, me and my buddies were also pretty tired by the end so it could be just that. Point is, the campaign is long BUT also well-thought out and super interesting. Not a single map or even section felt just thrown in for padding.

- The L4D animations work well enough with the Minecraft models. A little awkward at times, but it's effect is nothing but laughs rather than annoyance. 

- Minecraft music is featured! Another great touch.

- LOTS of attention to detail.

Cons:

- Occasionally predictable on repeat playthroughs of the same section. For example, there's this one section near the beginning of Chapter 3 (or maybe 4... I forgot) where there's always a heavy amount of Boomers and Spitters. And the Tank only seems to spawn during the finale so there's never that bittersweet "When's the Tank gonna spawn :( " tension.

Conclusion:

This was honestly one of the very best times in gaming I've ever had. This is quite possibly the most essential custom campaign to have in your addons next to I Hate Mountains. 

I wanna personally thank Deathreaper for putting the work he (and maybe others?) put into it. There's an obvious passion for the games of Minecraft and L4D (and just games in general), both passions I deeply respect. It really is no wonder why Valve featured this map.
