There's a bit of a catch to this achievement, you need to be playing the campaign online with friends but you need to be on a local server due to the dedicated servers being buggy and even if you fulfill the achievements requirements it simply will not unlock.
Now the trick to it is for you to force yourself as the local host, it's a very simple trick but for anyone out there who doesn't already know how to do this I'll do my best to explain!
All you have to do is set up the lobby as you normally would, invite friends etc, when you're ready to start up, press "A" to start and then just keep pressing it, it'll start the load up sequence and cancel it over and over, within a minute the menu will lock but the game will continue loading, this means you've successfully managed to pull it off, if you cant seem to get it to work try pressing "A" faster, it does work, I promise.
A big fat warning though, while there are no serious consequences to this, i.e. you wont get banned because it's not tampering with gameplay, it doesn't breach any rules! It does sometimes crash your Xbox, if that does happen just turn it off and on again, boot up and restart the process.
Now for the achievement what you have to do is have at least 3 human players (counting yourself), reach the finale or just boot up and start from it, clear out the main area and have a player go to each generator and wait, once everyone is in position and ready, have one person do a countdown and all press "X" at the right time, once the 3 generators are up and running the achievement will unlock.

We're both right Marx0r, the menu locks up and wont allow you to back out which will force you into the local server, however I was trying to explain it as simple as possible and when the menu locks up the countdown will remain at 4, which is easier for someone who doesn't really know what they're going to see!

I can confirm that the countdown does NOT stop at 4.

liddd, all I can say is that every time I've forced the local server it has stopped on 4 for me, however, I did also edit that out of the solution some 5 hours ago.

I can confirm that Lidd and Marx0r are confirming the truth. Confirmed?

Perdipt like I said to liddd, I've removed it from the solution, it does what I originally said for me but for whatever reason it seems to only happen to me, so I removed it from the solution to stop more confusion!

Fortunately the timing doesn't have to be exact. I got this with someone who didn't even know I was going for the achievement. I set up my guest on one generator while I and another random player were on the others. When I heard the random player begin to start his generator, I activated the other generators by pressing x on both controllers at the same time.

So would it work with Me + Online Buddy + Second Pad for one of us?

So long as you used the local server trick and have all 3 generators running at once, yes.

sweet so Im screwed out a cheevo.... thanx alot Valve u bunch of lazy fatty's!

The achievement isn't glitched, you just need to initiate the local server workaround and you'll be able to get it just fine!

Valve are a bunch of BS so I got the first add on right after its release and couldnt unlock achievements got rid of the game just got it back expected there to have been patches to fix the problem but no still the same old thing....I unlocked some of them in single player and now I get the second add on and its exactly the same.
I tried the method stated and all it does is crash my slim Ive tried tapping slowly but nothing happens and when I tap fast my xbox freezes....shouldnt have to deal with this BS just to get an achievement.

I know! I completely feel for you, unfortunately though it's the only way of getting the achievements to unlock! I wish I could be of more help!
By Jayour on 20 Aug 2011 22:06
No worries mate its not your fault, I actually got this achievement now through a friend getting local server and i've even managed to get local server myself but more often then not it crashes my xbox, doesnt seem to matter weather I get it or not as the exploding barrel achievement refuses to unlock I'll have to attempt that in single player.
You'd think Valve would fix these problems before releasing more L4D games.

I just got this yesterday and it was thanks to someone who had a controller with a turbo feature. I've tried the "button mash A" technique many, many times in the past and 100% of the time it would lock up my Xbox. But it appears that if you have a controller with a turbo feature that you can just hold the A button and the super sweet turboness will push the game onto a local server without locking up the machine.
By CHolland8776 on 03 Jan 2012 17:25
Just done this, for pressing A mashing it would cause my xbox to freeze, the way I got a server was to press the A button when the sound for pressing A stopped.

this worked like a charm for some friends of mine that I was in a party with, positive vote on thier behalf :)
By ClawColyer on 31 Jul 2012 23:10
Got it without spamming A as the few tries crashed my xbox. So, not sure if it just randomly put us in local server or you dont infact need to do it.

Got a feeling this is a stupid question but, can this be done via system link, 2 consoles, 2 tvs, 4 gamepads??
By CRT JEDIMARK on 13 Nov 2014 06:38
^ I'm curious about that too, mostly because this achievement flagging is online/offline.
By Mr Granstaff on 29 Jun 2015 18:13
I'm almost certain all the "online" achievements in both L4D games can be done via system link.

Use the game's forum or make a gaming session.

I don't know what you're talking about with the "countdown locking at 4". In my experience and according to a few people I asked, if you keep mashing A, eventually the menu will "lock up" and not allow you to back out of loading the game. That's when it forces a local game.
By Marx0r on 14 Oct 2010 17:48
I got this over the weekend, and can confirm that the game has to be on a local server (tried several times on a regular server and the achievement wouldn't pop). It kept freezing everyone's Xbox when they would try to force the local server, but worked on the first try for the person who had a new 360 Slim. So I would recommend finding a person with a Slim 360 to host the game.

at the same time until all three generators are activated. The achievement should pop up for everyone afterward.
