It's probably a problem with my mod. After downloading it again today, the weapons and ammunition can be picked up normally. However, I'm not sure what mod caused the inability to pick up weapons and ammunition before.
（估计确实是我的模组问题，今天再下载了一遍后，武器弹药可以正常拾取了，就是我不清楚之前因为什么模组导致武器弹药无法拾取）

no issue with ammo on my end.

Then you have an add-on breaking it. I don't change how picking up items work, so this is an issue with your game.

@Global It's not an ammunition restriction, it's that you can't pick up any weapons or ammunition after entering the map. The issue cannot be resolved by using the command 'cooluevac_changes_enabled 0'
（并非弹药限制，是进入地图后无法拾取任何武器和弹药。使用指令coop_evac_changes_enabled 0也无法解决问题）

There is an ammo limit. You can turn it off with coop_evac_changes_enabled 0

@Global Unable to pick up weapons and bullets in the map
(地图中无法拾取武器子弹)

I've currently no plans on fixing up the Abducted campaign. It requires quite a few edits, such as new dialog for the first map.

can you do abducted campaign

coop_evac_changes_enabled 0

shitty ammo cap, too many zombies, shitty ending. 10/10

wait a second..... you dont mean..

ok now for a sequel where its reveled the guy who shot is a terrible shot and we travel across a nuclear wasteland U.S. and undo his living privileges.

alr well hopefully something appear sin your mind man you do some wonderfull tweaked co-op maps

Right now, none

what other co-op tweaked maps are you planning on creating

хорошая работа,сэр

Florida to Pennysville in 24 hours? That's barely possible by car

too much zombies, laggin

NO, I WILL NOT UNINSTALL THE WHOLE 12 ADDONS THAT I HAVE (and i have a beefy pc)

i hate ammo limit

You can make zombies easier by setting coop_evac_zombie_hp_multiplier to a lower value.

way to many zombies, me and my buddy were all the time killed

this map is fun with the tf2 gamemode

Oh dang, glad to hear! It’s cool for having theese campaigns as sandbox again!

I'm currently planning on fixing up the Abducted campaign, but very little progress has been made on it the past few months

Would be cool if there will be other ports from perfect_buddy COOP maps

Oh my bad! Sorry for not seeing that earlier

Check the description to see how to remove the ammo limit.
Or just set gmod_max_ammo to 9999

Maybe make a separate addon or configuration in the map to REMOVE ammo limit?

Dumb bastard thought he could outgun a Repbulic Commando and get away with ****.
He wasn't prepared for the ACP Shotgun. XD

Thanks for the feedback! As for why certain things are what they are:

The shotgun guys were actually way too easy in my testing - try keeping a distance and using your revolver. You could also have an add-on that's changing their accuracy.

The zombie count is high because that's what I find the most fun. I play using TFA weapons (check the description) and they work wonderfully with the campaign, with ammo economy to match the high zombie count.
If the zombies are simply too tough to deal with, you can always adjust the difficulty via the coop_evac_zombie_hp_multiplier console command.

The end sequence is how it was in the original campaign, and I don't want to change the story.

there is a significant amount of effort here, but zero thought was put into gameplay. good enough story, but not very fun to play. things that could be improved:

* nerfing the people with shotguns, they deal far to much damage for their accuracy.

*get rid of ~70% of the zombies, there are simply way too many.

*perhaps make the end sequence a fight. it doesn't make sense that you can defeat hoards of zombies without issue, but it only takes one guy to take you down.

This is the best map I've ever played on

What's the FIRST song that played in Fort Myers called because I can't find it

Oh my bad, im not spend enought time to read des... ,thank for remind me.

There's an ammo limit in place to help difficulty. If you don't like that, try disabling my changes (check the description) or adjust zombie health so it takes less ammo to kill each one (also in the description)

any idea that ammo not picking up sometime, no matter how hard im press E with manual pickup?

No problem! I loved this campaign, which is why I moved it to sandbox.
Much more fun with your own guns and stuff.

Splendid! Thanks for converting it into sandbox!

oh ok

I gave it a shot, and unfortunately it feels too janky to recommend to others - sorry!

I'll check it out and see how it works. Thanks for the recommend

think you should add limakenori's headcrab latching into the recomended addons

alr. thx!

Yep! It's designed to be playable this way.
Check the description for recommended mods to help you do that:
Weapon: Setup, Transfer And Restore
Weapon Editor & Replacer
If you need help configuring replacements, let me know!

can i use other weapons like mw base or arc9?

You play this in sandbox, yes.

working on sandbox?

Played it by myself. Bus Stop was a difficult level, especially with the hordes still rushing through. Did do a little bit of cheating to try and survive. Made it to the end. Great maps, especially for the end.

That's bizarre. But hey, thanks for figuring out the cause!

Thanks, after some testing, I discovered the real cause is the following mods, [wOS] DynaBase - Dynamic Animation Manager and [wOS] DynaBase Legacy Extensions
