Pros:

- Some Dead Space Music
- Some Good Usage of Music

Cons:

- Not Covering all Left 4 Dead 2 Music Tracks
- Should Cover Infected Spawn Sounds
- Does not Cover Ambient Sound Effects (Tension Tracks)

Conclusion:

It is a good mod, but does not deserve a 10. This is greatly missing alot of tracks that need to be covered to turn Left 4 Dead 2 into a full-housed Dead Space 2 Theme. First and foremost failing to use all the infected themes, Chargers and Jockeys still use the same Left 4 Dead music. In addition, Stress tracks and Tension tracks are still LEft 4 Dead themed, and should be replaced by the ambient Dead Space 2 tracks that are used in the same essence. Also, some tracks such as Death, Incapication could also use the proper Dead Space 2 tracks to go along with it. It doesn't feel right if half of the tracks are Left 4 Dead 2 and the other half are Dead Space 2. Good try, but not enough pleasure out of this mod. I had to rip the sound tracks manually and do it myself to get the full effect, hope the author decided to fix that.

Pros:

- None

Cons:

- Doesn't Work
- There is No Change Log.

Conclusion:

Don't Download

Pros:

- Military Style Skin.

Cons:

- Doesn't Work.
- No Changelog Provided as Stated.

Conclusion:

It is a good Skin, but with no official instructions and usually as easy as copy and pasting into Addons folder, this mod is useless. Don't download until the author fixes the errors.

Pros:

- Pure Valve-Like Copy Campaign.
- Great Addition To the Pre-Set Campaigns of Left 4 Dead.
- Balanced GamePlay, Item Spawns, Infected, Great Script Usage.
- Unique Crescendo Events Based On Left 4 Dead 2.
- Minimal System Requirements, No Bad For Crappy PCs. Really.

Cons:

- None

Conclusion:

"I Hate Mountains" is just the perfect campaign add-on that players are waiting for. If you expect Valve to even contribute another campaign other than "Crash Course" then you are better of downloading this one right now. You won't find a better polished campaign on this website or anywhere else. This campaign has rarely the atmosphere of being a non-valve map.

With its well polished and scripted code that you do not even feel or recognize, the map utilizes Left 4 Dead 2's Pathing System and Crescendo Event! If you think Left 4 Dead 2 is not portable, wrong. This map clearly demonstrates how easy it is to copy some of Left 4 Dead 2's ability. Getting lost is only half the battle, this is not a con. This map has no negative feedback to you, other than the shameless ragequit you may demonstrate upon playing the campaign for more than two hours straight. If that is the case, you should return to Blood Harvest on Expert, because you won't find anything tougher than that.

This campaign is meant to give you a headache, if you cannot handle this much confusion and intense fighting you should probably return  to your crib. Zombies Only! If you have not downloaded this campaign yet, then its time to start using your bandwidth before zombies eat it out.

GamePlay (10/10)
You won't expect that different between L4D and L4D2. Sure, no Spitter, Jockey, or Charger. Why care? We don't need a sequel to enjoy what a sequel has, and this campaign proves it. Running Cresendo Event for the first time on Left 4 Dead 1 and what do you know? You ain't playing L4D2! The maps are layed out perfectly, each showing a nice easy path and also multipath.

Sound/Music (10/10)
There was new music included that sounds almost like the sequel, and new sound effects too. Not there was any sign of new voiceovers, but I expected better things than those wacky lines from Francis. Nothing more to say here, other than if there is new sound and music, its gold.

Graphics (10/10)
If you have a crappy PC, this campaign will still run like any other campaign. You don't need any better specs than those posted by valve themselves. There are new textures, effects, and more. Plus don't forget the secret password to hack into thier site? eh?
