Pros:

- Bosses (x3). 
- Semi-decent design. 
- Great armory area. 

Cons:

 - 1st Boss: Annoying, at best. 

- 2nd Boss: Bad choice for sound. Ear splitting, annoying, never stops (even after killing it). 

- 3rd Boss: nerve-busting difficult with endless horde + SI while trying to evade and shoot the boss.

- Lack of supplies in finale. Very straining with only a medkit and ammo when the boss insta-yellow/red's your HP. 

- Near/Is impossible to solo. 

- Bots willingly run into 2nd bosses path, instantly costing a defibrillator. 

Conclusion:

I prefer the previous maps to this one.

Pros:

+ Devastating difficulty
+ Nice item placements
+ Unique rooms

Biggest + of them all:
Forces cooperation with team mates.
Fight together, or die alone.

Cons:

- Such high difficulty caused many potential allies to rage quit, leaving me (often times), in a sticky situation, alone.

Conclusion:

Overall, loved it.

Hated the ending, as it's a tad depressing, especially after sacrificing 3 members to win the campaign.

P.S. Found your Easter Egg. 

Pros:

- Nice duplication of crash levels
- Holy #@$# boss fight
- Decent crescendos 
- Nice spread of weaponry, items and ammo.
- Great "Run for it!" ending.

Cons:

- Bill's corpse has an AK-47 instead of an M16 (yeah, I conned this. Sue me XD)

Conclusion:

It may be just me, but everytime my brother and I ran for the exit, there was a witch waiting for us. Hated that, becuase it'd incap a bot and keep us from getting "The Survivors have escaped!"

Pros:

- Great feeling of uncomfortable you get from surroundings.
- Nice layouts of the map.
- Epic fighting at the final stand
- lol'able end that confused the $#@% out of me.

Cons:

- So many chargers
- After 1-2 levels, Special Infected are extremely rare.
- Almost no SI's in defense
- Machine Gun placements can't turn to zombie spawn points.

Conclusion:

Great campaign overall, though I'd appreciate a break from Charger Mania. XD

Other than the machine gun placements not reaching the zombies cause they can't turn to face them, I loved it.

Recommending it for experienced/advanced players.

Pros:

- Epic gameplay
- Long campaign
- Great puzzles, unsolvable without common sense and a Silent Hill fan
- Brought back the old style gameplay of "You-need-this-key-to-enter-that-door"
- Teaches to conserve ammunition

Cons:

- Glitchy at second half. Allied NPC's and enemies alike were flickering like no tomorrow.
- Glitches make it near impossible to get through with bots glitching through and staying in un-enterable rooms (Wound up killing'em...countless times.).

Conclusion:

Great campaign overall, minus the oh so forsaken glitches.
If you don't have someone who's a fan of Silent Hill series, be prepared for a long....long...long stay.

Pros:

- Epic one stage campaign
- Nice horror effects
- Boss is fantastic
- Funny writings on walls
- When restarting, map can change certain areas completely
- When restarting, map can hide markings in different areas

Cons:

- Bots are stupid like no other on boss fight
- If restarting/replaying campaign, the markings change locations, making the search a massive pain, and keeping you looking throughout the whole level for hours on end.

Conclusion:

Great overall, but the markings locations are a pain to find, as they're never in the same place, making it a mass time consumption to find them again, and again, and again.

Pros:

- Epic one-run gunning level
- Great mini puzzles
- Bots know what the hell to do.
- Tanks at beginning are fun and hard to fight with pistols.
- Awesome boss and finale

Cons:

- Impossible to play on single player (sacrifice needed before releasing two-in-one tank door. Must have at least one other player to pass this level_

- The campaign being only one level, the credits screen shows zero for everything, from number of restarts/deaths to hit %. (Could just be a bug, unsure)

Conclusion:

Great map overall. Recommended for experienced players. Newbies will be slaughtered, noobs will whine. >:D

Pros:

- Nice weapon/item spread
- Great design
- Nice placement of scare objects and illusions
- Finale is hard, but fun

Cons:

- A bit cramped in some areas, but great map non-the-less.

Conclusion:

Epic campaign is epic.

Recommended for players of all skill levels.

Pros:

- Extravagant designs
- Maps are easy to navigate through, with multiple paths to choose.
- Weapon/item spread nicely
- Weapons are realistic in terms of location (i.e. You won't find a katana in a prison, but an axe, or a club of sorts)
- Finale is hardcore. Loved it.

Cons:

- None 

Conclusion:

Great map overall. Not one flaw in it. 

Pros:

- Nicely done details
- Maps weren't confusing (directions)
- Run like hell endless infected on finale
- Finally, a mounted gun placed correctly to help fend off the horde for friends!

Cons:

- Pfft...A con? I didn't find my Katana. XD
- Wish there were more maps.

Conclusion:

Great map. It gives experienced players a run for their money on hard difficulties, and the newbies a rough drop into the run-like-hell events.

Pros:

- Excellent designs
- Weapons/Items spread out nicely
- Finale has many points to defend, all without an 100% survival rate
- Maps have a decent flow (You know where to go).

Cons:

-Uh...Nope.

Conclusion:

Excellent map. I recommend this to any L4D2 player, veteran or newbie.
