Can a AI-controlled companion be ordered to take an action

left-4-dead-2

In L4D2, can companions be ordered to take actions?

Me and a friend have been playing. That means 2 of our slots are human and 2 are AI-controlled. We are primarily interested in giving 2 orders:

How can we order a particular companion to follow one of us while the other follows the other one of us?
How can we order a companion to pick up an item? We've noticed that they don't like picking up any extra medkits at the start of a level which we can deal with, but what about telling them to replace their weapon / medkit / pain pills?

We've tried using what seems like a command system (Look, Let's Go, Hurry!, etc.), which causes the AI-players to make verbal responses, but doesn't seem to affect them in any way other than that. Unless we are doing it incorrectly, of course.

The AI in L4D is pretty simple and can only manage a very limited set of situations (and not always the right way):

save you from an infected that incaped you (which fails most of the time)
pick up stuff (excluding any pipe-bomb/molotov/boomer can) - you can help by spamming the "Look!" verbal order while aiming at what you want them to pick up
heal you when your life falls under 50hp - you can block that behavior by taking your own medkit in your hands, preventing the bot from healing you

BUT if you don't have any other choice than playing with the AI (survivor), try to make the most of it:

AI can easily aim at infected that human eyes can barely spot, like a hunter in a tree, or any special infected hidden in Blood Harvest bushes, for instance
actually, AI easily spots a lot of things that you could miss (simply because you are rushing or because you are caught in a horde) - try to listen at their "Look!" verbal orders as much as you can
AI won't spoil precious molotovs or any grenade stuff, so while playing with AI, use it as often as you can
As horatio said, AI reviving a fallen teammate won't be interrupted if he gets hit: you'll be better off protecting the AI and allowing them to execute the revive than doing it yourself

Can you play L4D in 3rd person

This answer also works in L4D2, just it's the other way round.

Open this folder:

%PROGRAMFILES%\Steam\SteamApps\common\left 4 dead 2\left4dead2\cfg\

Create a file autoexec.cfg with the following contents:

alias fps "firstperson;bind F7 tps"
alias tps "thirdpersonshoulder;bind F7 fps"
bind F7 tps

F7 will now toggle between first and over-the-shoulder third person mode.

Left 4 Dead 2 accuracy – when can I stop shooting

I would recomend using hunting rifle, I've reached 95% accuracy at the end of a co-op campaign while using it once. But to answer your question: 1) Accuracy doesn't count kills, it counts hits. As long as you hit your targets you're doing well. And it doesn't matter who else is shooting the target. 2) From what I noticed (but it's actually hard to measure) bullets count as hits as long as they hit the hitbox and it doesn't matter if the target is already dead or not. Tank's hitbox disappear a second later than his actuall death. If you continue to shoot him, that's still going to count as hits. Common zombies' hitbox disappear a split second after their death.

P.S. L4D stats are often so bugged that I feel sorry for your trying to reach a certain value at accuracy...
