I did not finish and only had bots. They did great to be honest--gave me time to think. I had fun while I was playing. There really is no scoot n shoot here. You need to use logic and also DO NOT use gas cans on zombies. You'll be sorry if you do at some point. Great creativity. I tip my hat to the author.

Probably the hardest map to play

"Have fun"? You cannot have fun in this series of maps. They are the best, most inventive and imaginative L4D maps but the author is a sadist and he won't change. I've been playing them all again recently as an example of how to not make a fun map. A few small changes here & there could make them enjoyable, although still hard. People like hard maps, I do, but not unfair maps. The best thing about these maps is that they force players to co-operate, normally players don't work together, often they work against each other, but even when every one helps each other, we still all die & no one can be bothered to start again because the maps are too long.

The codes and locked doors are the gayest mechanic ever and ruin the campaign.

太tm难了，机关什么的挺有创意就是太tm难了

please make this balanced please istg the finale is ♥♥♥♥

a bit difficult but definately worth to have a try!

这地图真神了跟老外打了一局看不懂

算是国内必玩地图之一了，很多年前玩的了，偶尔拿出来和朋友一起玩还是很好的图

Interesting Aperture Science theme. Decent and interesting design...but ♥♥♥♥ you!

too ♥♥♥♥♥♥♥ terrible
this ♥♥♥♥ nearly kill me
and why unavailable in china?

难得要死 恶意拉满

@chuckpolk
I am sorry, but I don't think it is.

I tried playing this years ago but had no friends and could not do it on Single Player. I still have no friends, but I do have “improved bots” add on, so is this doable now?

Finally found this map after years of searching. I finally came across the map and the Yogscast playthrough I swear I remember it being a YouAlwaysWin video instead though.

@ Invisible Loki
Thank you!

This map was my first ever exposure to this game. Watching the 2011 yogscast playthrough on youtube, Thank you for making core memories.

很不错的机关图，很久以前就看过，略有点烧脑

옛날에 이맵정말 재미있게햇엇던기억이 나네요

@TaLlking death Take hotter than the surface of the sun.

最后一关有bug，有几率卡住一直刷坦克不开门

I actually really enjoyed this one. It was a great way to keep me on my toes

Is the final broken or something? I sat there fighting so many tanks for like 20 minutes and died and nothing was different
I think I got through twice RARELY

questionable ethics from the hit game half life and black mesa 🤑😱😱

why does this look like mirrors edge

太难了

@ Lọ Lem Hè Phố, maybe you got some addons that tamper with tank spawn? me and my friend played this map just recently and we only battled like 2 tanks only, although you have to retreat to the door (you can know this if one of the characters mention to start running) while being chased by a tank.

i thought this would be the half life map

Why the ♥♥♥♥ the rescue won't come like we have been defending against 30 Tanks at the last map for 20 mins. Does anyone encounter the same problem?

nice

I give you a like, since I adore the hell out of this one prior to Steam workshop being a thing

awesome!!!!!!!!!

funny

imma ♥♥♥ on ur living potential until u die

GOTY

In fact, hundreds of thousands of players like this map, but they are all pirates, because for some political reasons, it is difficult for them to buy the legal L4d2.

i love this map !!!!!

Valve should present this map as original

Questionable Ethics Remake coming soon!

Наконец мы сделали это :D прошли с начала до конца на эксперте,с триллионом перезапусков и не за один день. С миллионного запуска и супер-стратегиями завершили финалку вдвоем.
Это карта,которую как бы не горела *опа,но не отпишешься,пока не пройдешь :D
Определенно в избранное,определенно лайк и определенно будем как-то проходить еще :D Прекрасная проверка на прочность и удачу)
