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.

The campaign has an original theme, great visuals, plenty of custom assets, and moody atmosphere. It also has its share of special events, different routes, and gameplay mechanics. The maps, however, seem somewhat repetitive, especially when the game forces you to salvage car batteries in a fixed order, then backpedal half the map, all the while being attacked by micro-hordes - these are as annoying as a weak rain compared to something you'd want to use an umbrella in. The sound of the good ol' Soviet weather broadcast with "Manchester et Liverpool" brings joy to any post-Soviet country player, especially hearing the soothing voice announcing the temperature in Ukraine, reminding of the times when Russia and Ukraine were sister states. Some graffitis are misspelled, but usually not to the point of pure ridiculousness. The health and ammo supplies are less generous than I'm used to, and considering the lasting-ness of the campaign, this does not help its replayablility. I finished the campaign solo without cheating on Normal.
