Played on advanced with three bots, did not finish. It starts off very strong; the aesthetic is fantastic, with the lighting and attention to detail in the map. The first map was short enough for a starting map and was fun to play, especially when looking for fuses which spawn randomly. I would say the first map was the best of the four. The second map is where things started to go downhill. Like the first, the map looks great, with excellent ambience and attention to detail which not only is pleasing to look at, but also helps point the way to go. However, the second map very linear and is fairly long, especially when considering it ends in a timed hold out against a horde. The third map is by far the worst of the four and may be one of the worst L4D2 experiences I've had the displeasure of playing. Like the second map, it is much too long in length. It starts with a wide open plain with an entrance into some sewers. The horde triggered upon entering the sewers is much too easy to deal with, as the only way points to the survivors are through a narrow doorway, and up a ladder. Once in the sewers, I found myself wanting greatly for any kind of tier 2 weapon, grenade, or small health item. You'd be lucky to find any pills in the map, let alone adrenaline for when three of your team mates are down from the constant hordes. That's anther problem, the hordes. Map 3 has hordes at every turn. First there's a horde when entering the sewers. Then there's a horde opening a gate in the sewers. There's a wide open area with a tower you must climb up to press a switch. This switch starts power which triggers a horde. The horde will not stop (which is not mentioned) until you press and hold a button on a generator back down below the tower. The tower itself has a turret on it which is nice, except it's positioned to cover only the least used direction commons come from. Once you've cleared the gate, there's a choke point ladder which is very hard to clear out from below; good luck if a boomer is camping it. Normally, this ladder should be the end of the map, which I initially thought it was. However, exiting the building you emerge from, you enter a wide street setting littered with broken down cars. Now you are tasked with finding two car batters, each of which trigger a horde upon collecting, that can spawn in random locations. Searching for these batteries is extremely tedious. Their possible spawns are all too far apart and they do not have any ammo or guns to hunker against during the forced hordes. When you find both batteries, then you must construct some kind of gate to proceed, and when you trigger the fuel pump to open said gate, it forces yet another horde and tank at the same time. You'd think after all that, you would finished with the map, and yet the map continues, you need to go through a pool and through another open street to get to the final building which finally contains the third saferoom. The fourth map is the finale, however I did not get to see how the campaign ends. When I set the first explosive and triggered the endless horde, I found myself stuck on the rooftop with nowhere to go. The only indication of direction I could find was the graffiti on the walls which was blocked by a wooden plank. I did not get to explore any further as this was when my game crashed, like so many others' have too. Overall I would say there is some clear talent shown in this campaign, with the art style, the custom item hunts, and the voice acting all should have led to a great campaign. The major downfall of course was the map design. Too long, too frustrating, and too random. I would not play this campaign again.

Chapter title overlay, music and intro accentuate the effort author has put into building the map itself, and the aesthetic and build of the map prove the map itself to be superb, but only aesthetically. The gameplay was honestly the most frustrating and poorly built one I've played, yet. On Map 2, where the survivors have to blow up a plank on the wall to open a way to the elevator, SI's and CI's have no problem walking through the indestructible plank to attack survivors. A lot of the infected spawns are blocked off with barbed wire, but the survivors can be pulled in through the barbed wire by smoker or charger; they cannot get out. Chapter 3 has too many entities, so it cannot even be played. Chapter 4's finale has some nice concepts, but the constant horde while the survivors fight off the tank is beyond annoying, and downright heinous. Is it a challenge? Yes. Is it a fun challenge? No. In fact, it biases me to give this a 2 instead of 3 or 4. Bots are incapable of climbing the ladder where the second C4 is detonated. While bots aren't the smartest players, they certainly do help, and having only 3 people defend against a 2 tank finale sequence without even 5 second "break" period is mentally exhausting. I honestly would have had a better L4D2 experience without having played this.

I'm a big fan of Stalker: Shadow of Chernobyl and Metro 2033, and this campaign just mix everything that i like. Zombies, radiation and reality. The level design cross the line of absurd. So many details that is hard to pay attetion on zombies. A hard campaign, thank god. New gameplay, with some custom events. Its just, amazing. The campaign has some problems, this, everyone knows. May occurs crashs and fps drop. But yet, stills worthy.

M2 always spawn Tank after the door is exploded and infinite zombies spawns,aced over and over because impossible to fight tank in such a situation and WHY design M3 such unfriendly? just keep spawn zombies run after us, never ever stop! this is BULLSH/T in realism expert mode, and after we reach the door of Green Box,we cant get into it because god damn BUGs cause we cant pick up any mission ltems,seriously, NOT a good experience totally.
