No, you don't need to do anything to activate the addon. Just make sure it is enabled in the addons menu in-game.

Only cosmetic addons will work in multiplayer. Scripts addons like this won't work. I'm not sure if there is a way to get non-cosmetic addons working in multiplayer.

Ima ask. Do i need to do anything to activate this mod ? Like writing a code,Pressing a key,restart the game... And can i play with that mod with my friend ? If he has the same mode at the same lobby ? We usually play 2 players and we swear alot to the bots doing nothing. This mod LOOKS so great and i hope it works. If it doesnt work please help me Ziggy. Thank you.

Does this work in co op?

*larissa* no.

Do you have to be host for this to work?
Ziggy  [author] Jun 4 @ 8:00am 
Those are all default bahaviors for the bots. I don't have the ability to modify those behaviors with the limited modding system in this game. Unsubscribing from the mod will remove it. Check your addons list in-game to see if it's still installed.


No, they cannot pick up gas cans. I can't make them do so either.

Can they pick up gas cans?

Well there is quite a few, they save me at the last second from any infected trying to kill me, they never take any medkits from safehouses unless I already had one and didn't use it at all, sometimes when I'm playing a map I will turn around and they will be miles back, a lot of the time they stand there being attacked by a horde and usually go down, but my biggest problem is I can't uninstall the mod, I've unsubscribed, disabled it, validated my game files and even re-installed L4D2, and it still doesn't work. I do appreciate it though it is a good mod in all honesty, just seems to be happening to me.
Ziggy  [author] May 31 @ 5:09pm 
If you wouldn't mind, could you provide some examples of situations where you feel the bots are less useful than the game's default bots? There are many default behaviors which I could not improve, but they shouldn't be any worse than the default bots.
John Wick May 31 @ 12:11pm 
Lol, makes them so much dumber.
GDRacer14 May 26 @ 11:31am 
Its a shame that single player versus servers shutsdown the server after a couple of minutes
Atlaimond May 25 @ 12:43am 
Thak you.
Up-voted.
Ziggy  [author] May 21 @ 11:43pm 
I recommend using the simple version of the addon if you want to earn achievements. The only difference between the simple and advanced versions is that the advanced version has a radial menu with a few bot commands on it. However, since using those commands will disable achievements you're not gaining anything by using the advanced version for achievement goals.
SKELETOR May 21 @ 7:49pm 
i downloaded this addon because i was thinking that i finally could get the expert campaigns achievement, but the new menu doesn't gives me the option of changing the dificoulty, unless i change it inside by voting.
Can you update the menu so we can change the difficoulty
Ziggy  [author] May 21 @ 6:40pm 
No, there's no way for me to add custom maps to the new single player menu that the advanced versions uses.
´◓ɷ◔` Skeleton Bread May 21 @ 6:33pm 
your saying advanced wont work on unofficial cause
Ziggy  [author] May 21 @ 5:20pm 
No. You will need to start those maps through the dev console. There's nothing I can do about that.

You could also subscribe to both the simple and advanced versions of this addon, then use the simple version for custom maps and the advanced version for official maps. Just make sure you only have one enabled at a time in the addons list.
´◓ɷ◔` Skeleton Bread May 21 @ 4:05pm 
is there an option to choose unofficial map as versus and other modes.
killer ardastar May 21 @ 1:10pm 
way better that thos shitty old bots who follow my ass all the time
Ziggy  [author] May 21 @ 10:36am 
I don't think that's something that can be changed.
ObeseRat May 21 @ 8:07am 
I mean, can you make the bots' top priority for choosing a secondary weapon to be the magnum?
Ziggy  [author] May 21 @ 7:48am 
@fresh<bread>-_-10:
Not included. A lot of people seem to have issues getting single player versus to work, and most maps cannot be completed by bots anyways. It's not worth my time to add a second variant of versus in.


@ObeseRat:
Not sure what you mean.
ObeseRat May 21 @ 5:37am 
Would you make Magnum the top priority for secondary weapon please(in both simple and advanced)?
´◓ɷ◔` Skeleton Bread May 20 @ 4:49pm 
wheres versus realism?
GentleMEEM May 20 @ 6:04am 
Oh ok, ty for responding, i already changed the addon to the simple, but thanks anyway
Ziggy  [author] May 19 @ 7:11pm 
That's intended. It's the only way to allow cheats to be used in the game. You can use the radial menus in-game to select character and difficulty, or just use the simple version of the addon if you don't want to use the radial menus.
GentleMEEM May 19 @ 6:48am 
Ziggy, if you dont mind, i have a bug report, its in the menu, when you select a singleplayer campaing, the selecting menu will not appear, instead it will appear a list of maps, it doesen't show the campaing picture, you can't select a character, you can't select the difficulty, it's just a campaing list and you click it and it instantly starts the campaing.
Ziggy  [author] May 16 @ 9:55am 
I'm not sure. I would have to test that to find out. If that is the case then it is something on Valve's end, not something that I have the ability to change.
Keel the Swift May 15 @ 12:37pm 
Alright... then I'm really not sure why, but when comparing the vanilla AI and this AI, the vanilla AI would shoot the tongue while running at me while for some reason, this AI doesn't shoot smoker tongues at all now.

Is it possible there's some sort of conflict between the timing (reaction timing) between the setting for meleeing and shooting?
Ziggy  [author] May 14 @ 9:33am 
I didn't actually change the AI because the limited modding system for this game wouldn't allow anything lie that. I just changed a bunch of settings that relate to bots. The only settings relating to special infected is how quickly bots generally react to one of them restraining you. I turned that setting down as low as it can go so that bots react much quicker to that.

I can't change how they react, nor can I make them react any quicker than they do now. It's just not possible with such a limited modding system.
Keel the Swift May 10 @ 2:37pm 
[...continue]
I noticed a similar problem with Jockeys where when one jumps on me, it drags me away and the bots are awkwardly trying to chase it down rather than shoot it. This one is less of a problem cause I can still somewhat fight it and they eventually catch up.

So, all in all, the bots are indeed better if they react at all rather than stand there confused. And yes, I understand AIs are difficult to make and this wasn't meant to be a perfect replacement, but maybe you can add an escape clause (like after trying 3 times or after 2 seconds, they change behaviour, i.e. shoot instead of melee)?
Keel the Swift May 10 @ 2:37pm 
One major problem with the new AI is how it deals with smokers.

Countless times, I've been dragged into places where bots have a hard time walking to (needs to jump, or heck, just on top of a pile of rubble) and they just stand there staring at me cause they can't melee me. The annoying part is I am literally right in front of them, if only they can be bothered to use their guns. So I go from full health to death by a single stray smoker.
They also struggle when I'm dragged to the other side of a small fire. Instead of trying to walk around it, they slowly burn themselves going straight line towards me, then backing off and repeating that cycle.

i subscribed to this, played scavenge single player, was best of 3, i collected 1 gas can and won match 2~0, but didnt get the form a team 4 v 4 achievement ?
Sturm Krahe Apr 30 @ 8:59pm 
How do you toggle melee weapon use?
Ziggy  [author] Apr 25 @ 2:15am 
No
Destroying_Sun Apr 23 @ 5:29pm 
Can they use Pipe bombs and molotovs?
Ajax Apr 19 @ 9:05am 
@Ziggy:
Ok; that makes sense. Thanks for the response!
Ziggy  [author] Apr 18 @ 11:02pm 
@Ajax:
Cheats can only be enabled on what is called a listen server. In order to be on a listen server you need to start the game through the developer console. I created the new single player menu to do that for the game's official campaigns, but I can't make it detect the custom maps you have installed and automatically add them to the menu.

The core features of the addon will still work, but you won't be able to use the radial menus unless you start the game through the developer console.
silverslayers Apr 18 @ 9:33pm 
ya its also with certain vinila campains other them that its AWSOME
Ajax Apr 18 @ 7:40pm 
Love this mod! However, I noticed a bit of an issue: when I try to play an addon campaign (like, say, Suicide Blitz 2), I can't use the bot commands because sv_cheats refuses to be toggled (i.e. bots are as before, but I can't command them). Do you know what might be causing that?
The iron giant Apr 17 @ 2:08pm 
Why is it that everything when i play the sacrific the game says you most at least have two sruvivors
The iron giant Apr 14 @ 1:50pm 
U should put realism VS
N.Daniel Apr 13 @ 6:29pm 
Thank you for your answer.
Ziggy  [author] Apr 12 @ 6:58pm 
Yeah, that's normal.
N.Daniel Apr 12 @ 5:11pm 
Hello. Is it natural that bots don't collect gas cans on their turn on scavenge? I guess it's impossible for them to play a mode they weren't coded for but maybe I have a setting off. Just double checking. (Sorry for my poor english)
