Really good Map! No crashes happened! This Map is so big and tons of exploring to do and I love the scenery at Map 5, its Hoover Dam and I love day Maps instead of night. If youre stuck in your way, just use the the electric switch (follow the wires) or shoot the barrels (be careful this Map has so many barrels so watch your fire!)

Map 1-3 are fine
Map 4 is scavenge 9 gas cans, I suggest get the gas cans IN THE SEWERS first because its far and scavenge the gas cans near you. Once youre done, way to Safe Room is open.
Map 5 is hold the line: HORDE > TANK > HORDE > TANK > HELICOPTER

Optional: Since this has multiple Add-Ons, I suggest do this guide before you play this Map to avoid conflicts or crashes: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3294748023

CONGRATULATIONS, I GIVE YOU 10/10 ON THIS MAP! XD

anyone cant find this campaign in campaign list , even on normal Campaign game mode ?

This campaign is almost as good as Black Mesa: Fallouts. The graphics aren't quite as good. Some people may get quite a bit of graphics lag in the last map. That's really because of the Left 4 Dead 2 game engine. I didn't have much of a problem with the bot players. I think one of them did fall off a ladder in the map with the generator that needed to be filled with gas.

Errors everywhere at the first map :/
This appears to break propane tanks, making them unable to spawn and deletes them if somehow picked up. Tested by launching the game with only the addons from this campaign and it still happens.

Campaing starts alright with chapters 1-3. I really liked walking through the facility.
Chapter 4 becomes tedious at the final part.
Chapter 5 is just plain boring, it doesn't stand out as a final chapter.
There was lack of resource through my playthrough, at one point I had to fight the tank alone using only a crowbar and a boomer bile (which was really funny).
Overall, hardly decent, the most outstanding thing is that I play in the black mesa facility.

5.5/10

There's a godspot in the final map, accessible just by jumping on the back of a truck. That probably wasn't accounted for!

这张图与另外一个Black Mesa Campaign [Update 1.3]互相冲突,两张地图的mission name相同,导致无法在附加内容查看,并且有大量的半条命材质,装在服务器上会影响所有的地图第一章开头动画,而且煤气罐失效打不爆,建议游玩后移出addon

The dam map
Low FPS

In the second chapter, the wall inside the fence has a missing texture, I'm assuming that's the texture of the bullet hole, is this happening because of a conflict with another module?:confusedensher:

Very good and fun map but kinda short and simple

nice map but short 8/10
artifiyings 22 Feb, 2024 @ 8:53pm 
out of all of the black mesa campaigns i've played, this is by far the best one.

Good map :steamthumbsup: , only a little audio bug in the last part when the first tank appears , ty
✞☠pretty☠✞ 4 Feb, 2024 @ 7:48am 
There were a lot of missing textures, plus some errors, the decals and textures addon i installed didn't work. I think it's due to this campaign being made 2 years ago

4/5 Fun field trip to Black Mesa Research Facility!

- surprisingly not laggy considering the file sizes of many custom content
- as others have mentioned campaign pacing are way off between maps, but still doable solo even on higher difficulty
- props used from Black Mesa have wierd shader / light baked / not sure the term, most noticeable on finale cars
- missing textures of what seems to be bullet holes sprinkled throughout first few maps
- and finally, messed up intro camera placement, noclipped through ground

这图真的很好玩~~~8/10

Crashed once and stutter in certain areas. But, it was a beautiful campaign, aesthetically.
Marcos 5 Oct, 2023 @ 1:42pm 
kinda good and fun but a lot of crashes (3). Short maps/ Map 4 is the best - it could be easy a final map.

Pacing of the campaign could be better. Maps 2 and 5 were easy, whereas Maps 1 and 4 were significantly more difficult. However, there were plenty of resources provided to counter to the endless horde events. Moreover, I wasn't a big fan of the invisible walls used to block off parts of the map. But the overall campaign was VERY beautiful, especially the final level. I could tell a lot of work was put into making this a very aesthetically pleasing map. Did a great job capturing the magic of Black Mesa. Overall decent campaign

7/10

Your addons cause the propane tank for the entire game acting wierd (texture broken, object for the world doesn't exist and cannot be shot)

Very nice campaign with one minor drawback; author(s) should remove the curved geometries that make the framerate drop (see below).

It's well made, quite thorough, lots of unique terrain. The chapters aren't too long, and there's a decent variety in gameplay. Looks very nice, and it's quite different from practically all the other maps.

The only drawback is that it uses a lot of curved geometries in the final chapter. Source engine handles this very poorly, as it prefers squares and straight lines. So making curved arches, pits, etc. with just eg. curved concrete (instead of using props) makes it drop framerates like crazy.

Hence, on the final map, you get stuttering and low framerate everywhere, p much regardless of your rig and GPU power. Fixing this would involve a bit of work, but it would make it quite flawless.

shittyest fanmade HL series map ever

Trog 12 Sep, 2023 @ 10:23am 
My game crashes shortly after the Tank spawns in on the first level every time.

Great mod but it messes up the trash bins on all maps, do not recommend it just for that reason alone, if that was fixed then I would have no issues.
