No Mercy has always been my favourite map, likely due to the nostalgia factor of it being the first campaign in L4D1 all those years ago. Would still rather play through than any of the L4D2 campaigns to be honest. As has been said by others, this campaign has just the right amount of tweaking, the way that previously blocked off areas have been incorporated into the survivor route has been really nicely done. There is a perfect mix of new areas which merge in to the old seamlessly. The train event is a nice touch and the Finale has been remade well, opening up a lot more rooms and giving a lot more options when it comes to playstyle.

I didn't run in to any major bugs, the only issue was with the tunnels in the sewer, if you run close to the edge you can see the skybox poke into the side of the screen by an inch or so. Not a massive problem and by no means game-breaking, but it is there. Other than that, I didn't see much that made me think 'this is custom-made', which I think is great. Had no tank spawns between chapter 1-3 which was a bit strange, but have only played the map once so could have just been pot luck.

The other big thing which has been mentioned by someone else, is the frequency of ammo piles and item spawns. I played the campaign on Normal as I wanted to spend more time exploring the new areas, and realistically you should never run out of ammo on the standard No Mercy on normal, but they did appear far to frequent. I started the game on my own and by chapter 3 had a full group of players, and at pretty much all times we had a grenade, medkit and pills / adrenaline, to the point where we could happily waste a grenade to pick up the next one. I'm not sure whether this frequency was intentional or whether these are all the potential spawns supposed to be generated at random, and something has bugged and made them all spawn at once, but as this is the biggest noticeable element, it isn't bad.

If you love No Mercy I'd 100% recommend giving this a try, I loved it and am sure it will only get better with minor tweaks.

Some bugs I've noticed

- At the start of the campaign, the survivors don't say they have to take the subway to Mercy Hospital.
- On the first and second maps, the sign for Mercy Hospital is kinda messed up

- On the third map, there's almost no rain, but I don't know if that's a bug or just a design choice.
- During the final, News Chopper 5 seems to repeat some of his lines.

Other than that, there were no noticeable bugs. Great campaign BTW.

Could be on my end but the commons population isn't working correctly, it just spawns default l4d2 commons

Are you using any population mods by any chance?

I'll try to swap out the l4d2 populations if I can

I played the campaign with that mod and saw the right commons, so it can't be that mod.

I uninstalled every population mod and anything that might conflict with this campaign and it's still spawning l4d2 commons

Do you have any other campaigns installed? I know those sometimes come with their own population files. If that doesn't help I don't know what else it could be.

It has to be this campaigns population file, I don't have any other campaigns or anything

I have no idea what else it could be. Sorry I couldn't help.

No worries

fixed it... somehow

Last two chapters, my bot friends (all 3 of em) decide not to shoot at commons any more it seems.. They just stand there getting hit, they do kill special infected tho.

I changed it to easy and made it thru to finale but the bots are still just standing there not shooting any common.

This seemed to happen after I put down an explosive pack. I don't really know but it was the first time I ever experienced this Don't usually play on single player tho, just testing out this map..

okay so when started the game there's not lot of zombies only less zombies

The doors with glass inside of them z-fight with the walls. (i think this can't be fixed, but idk)

There are a LOT of item spawns.

==CHAPTER ONE: APARTMENTS==
The 2nd ladder on the roof after the apartments doesn't work properly (all the others let you climb down instead of walking over them).

After the apartments and before the ladder, the tv should be off. (I like it better lol)

After exiting the building with the police car in front of it, there's a flaming barrel among other lights which can distract from the door. The police car also blocks the view of the door.

The building with the garage door after the ladder has a light switch inside with an outline? It's kinda cool but it doesn't have much of a purpose.

The cubemap in that same building is a giant clock.

Before the saferoom there's a spotlight that lights up the room too much along with having multiple light sources.

==CHAPTER TWO: SUBWAY==
Past the vents, there's a flaming car blocking the exit. past that there's detail you'll never see. (it's also inside the 3d skybox).

You can stop the train from moving by standing on the windows.

Near the end, there are a lot of cars with lights on. (van, taxi, car, police car) when all that's really the searchlights are already on top of the saferoom and the helicopter flies past so there doesn't need to so many lights on.

==CHAPTER THREE: SEWERS==
You can see the 3d skybox i think??? above you at all times.

There's an ammo pile spawn in the store almost right after the saferoom.

The gas station doesn't break into pieces and fly into the air ;(

The little warning signs on the door and wall directly after the gas pumps have broken reflections which show up as missing textures.

The door leading to the next area after the storage building should have more detail.

Before the saferoom, there's two police cars that kinda just add meaningless light. the point of interest is already illuminated, and the police cars aren't even pointed towards anything.

At the same point, there's like, two floating circles above the hospital?

==CHAPTER FOUR: HOSPITAL==
Directly after the saferoom, there's two weapon and item spawns on the main path.

In that same room, there's many light sources.

the cool-looking glass should have something go around the edges to make it look nicer.

At the original section of the construction potion of the hospital, there's a generator attached to lights via wires, except for the one behind it.

==CHAPTER FIVE: ROOFTOP==
There's a chainsaw directly after the saferoom right in front of you.

In one of the rooms, there's like nine different guarenteed item spawns.

One of the buildings has an out-of-place, weird-looking texture.

The hidden bar area is cool, I just wish it was more obvious it existed. I had no idea about it until I read the comments.

There's cubemaps on each corner of the rooftop, which makes the windows of the hospital turn red. (why are they even there?)

Overall, the map's pretty cool. I like most of the things it added. The train event is cool, the new rooftop is cool, and the new sections are cool. Hope to see this map improve! :)
