好玩，但是优化不行，140fps掉到25

bots will not pick up ammo on map 5, and have a tendency to fall of the tree log that you have to cross during the rush after destroying the helicopter.

Annoying how most of these campaign mods ALWAYS need 1-4 extra mods to work but fine, i'll give it a go since these HL campaign mods are usually 10/10

玩了很多三方图，这张图忍不住第一次评论，神图！
20/10

Pretty good and pretty tough.
Pretty fun,
no bugs
Absolutely awsome maps design
10/10

真难，而且貌似第五关有bug，独木桥那里电脑一直跳河

m5一直闪退

好玩，但是第五关水路太折磨了

1 hour and 36 minutes (normal)

This map is CHALLENGING, INCREDIBLE AREAS AND VERY LONG! 6 MAP CAMPAIGN! Remember to do some errands to clear the path.

Map 1 - Breathtaking area, lighthouse, ocean and mountains. Normal.
Map 2 - Just a cliff side walk. You cant cross the bridge because it has barrier but you will cross riding a catapult rocket. Normal.
Map 3 - Enter a military base. WATCH OUT FOR SNIPERS, THEY SHOOT YOU WITH NO REASON. Keep moving on.
Map 4 - PERFECT, a mix of Resistance: Retribution Chimera Base (PSP game) and Lockdown 2 (Custom Campaign). BE CAREFUL, NO RESCUE CLOSETS HERE AND DO NOT TO FALL OFF OR YOU DIE!
Map 5 - Mix of Cold Stream and White Forest Map, the howitzer ammo is inside the cottage, get it to destroy the Helicopter that SHOOTS YOU.
Map 6 - Hold the line: HORDE > TANK > HORDE > 2 TANKS > HELICOPTER

10/10 MAP! XD

很好玩，流程长，量大管饱。总共六关，第一关就开始展示机关神力了，寻路也废了点时间。由于我是带着三个人机打的普通模式，确实还可以，除了第四关，引爆C4要逃离的时候，被舌头阴了三四波，直接重开了。第五关建议拿360发子弹的冲锋枪，喷子不行，尸潮太多了一路上。
确实好玩刺激，下次叫朋友一起打。多来点这种高质量神图吧

难度很高，很多地形杀。P3碰到狙击手前的下山坡道有几率会在山顶上刷个smoker，然后会被这畜生拉进山体里，然后遁地只能重开，很搞人心态。

神

骂难度的打个图都破防？

傻逼地图，最后一关哪来的路啊，我靠，真他妈这么人

too long for expert

"Prevent Three party Map Script Pollution Extension"
Where can I find this?

Jeszcze jej nie skoczyliśmy ale to już nie długo

支持大佬

很早就和朋友一起通过写专，太好玩了

几把图，每一关机关刷尸潮，加上特感，地图长，流程长。单通难度更是大

Each level is gorgeous and lengthy. I loved exploring the different environments, especially The Combine's citadel. It was a good mix of original level designs and familiar Half Life 2 content. The cut scenes were also a very nice touch, such as when the survivors used a projectile from a Combine outpost to cross a gorge. However, this campaign has a few game breaking bugs. Map 5, the artillery wouldn't go off after putting in the shell. Sometimes bots would all go fall to their deaths. Moreover, the countdown timer in Map 4 made things very fun and intense, but escape pathways could've been more clearly instructed (particularly after climbing the first ladder, where often bots jump to their death once again). Having to redo some of the levels due to these did make things somewhat frustrating, especially considering how long each one can be.
However, the overall map is very beautifully designed and well paced. I highly recommend for a playthrough, but don't do with only bots.
8.5/10

尼玛，这图打了我头昏

神图，话说这是半条命的地图么？我印象里半条命的地图都是粗糙的要死
制作精美的同时风景还不错
6关且每关都很长，部分地形狭窄，就是老是崩溃，磕磕绊绊打了快三个小时，导航做得很好，容易迷路的地方设置好高亮
就是没搞懂第二关隐藏关怎么玩的，还有就是第三关前面贴图不太行，手电筒部分生效，还碰到第三关安全门打不开

大佬我想请教gmod地图移植的问题 gmod有很多地图适合移植到求生 不过我没有技术 向和你求教 或者说定制 我出钱 你帮忙移植 这样 可以吗？

好难啊，一次刷四个特感

with everything subscribed here . game crashes everytime i get into the elevator on map 3. and i cant seem to check whats causing the unexpected crash. so im unable to play this. ill skip this for now

之前在GMOD玩过这地图

innecesariamente largo. repetitivo mucho pero bien diseñado de ambiente.

Não jogue esse mapa com bots ou irá passar raivar com muito estresses, e com bots não termina o mapa pois tem muitos bugs que fazem os bots auto morrer.

神图，10/10

@板烧鸡腿堡 , probably you just don't suit custom campaigns with missions. This one is easier than Silent Hill campaigns, RE series, "Curse of Lazar Castle" & "Left 4 Dust" in terms of missions to operate & collect things. So if you suffer much in this campaign, probably you'll need to avoid those campaigns I mentioned before. Last time I played this, I had no problem in finishing this campaign to the finale.

If you never try shit, try this one. The worst map I have ever played before. No fucking story to tell you what happened. The only thing you have to do is shooting for nothing. Don't even know why people shoot you. Playing this map is like eating a big shit. I don't know why so many people like this map, I guess they really like eating shit. I don't even want to complain the bug inside. Just the pace make me disgusting. I don't know where this mission happen and why we should take this mission? I really curious why this map can't have so many good reviews? How much money did the authors pay? Where will we have so many zombies in each area?????

开局把字幕关了怎么重新开启？

改之前已经很好了就是p5有点空，改了之后p5难度太恐怖了，炸了石头之后无限尸潮又带着猛刷口水，口水一吐bot就不会走就会被尸潮围攻，同时charger也刷还tm有地形杀，我自己和bot都有在p5被charger创到即死区域导致gg，有一次更加恐怖在前文的口水和无限尸潮下还刷了tank，直接被小僵尸围攻倒下tank完成补刀玩家红温怒砸键盘；建议p5再改改，之前的版本能给10分满分，现版本7分吧。

在图里看到作者了，应该是个小彩蛋吧
难度还是有的，特别是我这种单人玩的，堪比三百六十五里路。一共花了102分钟通关，主要是人机不互动啊

不是哥们，第四关安装完C4上了电梯怎么我人卡回电梯底下了？？

I see potential based solely on the visual design and the way the maps are built in some aspects. However, the maps being so long that I can't finish the campaign without crashing on the way and various other problems, made my experience so much more stressful and anger inducing, I usually play on advanced with not much difficulty so this could be hell on expert.

At least 4 hordes per map and 3-6 tanks halfway through and so on, many areas that require you to corner yourself in order to start a horde BY YOURSELF, extremely long unneeded battles (end of 3rd map), and the chopper.

3rd safe room is bugged, the only upgrade you get is a free incendiary ammo upgrade because the previous survivor bots pick up the rest of them. 2 terribly positioned laser sights, one costs you to fight 2 tanks. You will easily lose your tier threes in the fourth map because of its design.

I have yet to finish it without dying or skipping stages because its designed so that is nearly improbable, lol.

想知道m5的安全门如果被内鬼插件的克打烂了 是否就不算安全屋了 今天碰到了这个bug

不知道为什么第四关到第五关换图会闪退，插件和mod都关了也这样

I really love the map it amazing only in map 4 unlocking the locking door bots cannot find patch to get in to refill their weapon it kidda make the game harder in that part and sometime they struggle to get in safe room but it not really a huge problem so it alr and in map 5 they have problem to climb up to helicopter. But still this iz a very great map just there some Chinese text when Bill talking to you I don't really understand the map story in that part

FUCK THIS MAP! Each level is so long with so many bullshit areas where you can die so often.
Level 4 has a hold out section at the bridge where an infinite horde spawns as the elevator lowers. But the map is so bad that you don't have anywhere to survive. When you get in the elevator, you are forced to wait for your teammates to enter. If they get pinned, you can't get out. If a Spitter spits in the elevator, you are dead. I played on normal and I lost 3 times in that spot.
Level 5 is worse. There is a section where you get to a chopper shooting at you if you get too close. Your teammates get shot and don't even notice it. After you destroy it, a horde spawns. Then you have to destroy a rock, a horde spawns. Then the helicopter crashes and an infinite horde spawn. You run down the path, LITERALLY FOR NO REASON AT ALL your teammates die. This entire campaign barely has any closets. I was left to run a gauntlet until I was pinned. Unless you have a full team, do not play it.

Couldn't figure out where to go on part 3. Quite confusing at parts had to suicide and let bots finish or just skip around the maps

第二关开炮，第五关炸石头后的白线区域这俩触发动画时如果身边有小僵尸还是会被挠倒，希望可以优化下

一不小心字幕关了，咋重新开启，连重新订阅都出不来

Improbably long. An average run should net about 7k-8k zombies. So many crescendo events. Not fun enough to justify how long it takes.

这几个月玩过最好的图。顺便问一下，这个“防止三方图脚本污染拓展”在哪里下载，真的非常需要这个插件！

M5更新后人机过独木桥桥那块会自己掉下去摔死
