Hi all 

Trying to get the chain reaction trophy but cant get it!!  anyone got this trophy and if you have how the ef did you get it?

I've tried barricading the tunnel to alderney,  standing on a building at the star junction and rocketing everyone from behind.

HELP!!!!!!

I've stoped a car in a bigger street and just throwed some granages to the cars.

First you need a rocket launcher. Then, on the first island there is a place similar to Paris' Arc de Triomphe. Just stop on one side over there, wait in front of some cars and watch them pile up. Then shoot 3 rockets against the cars very near to eachother (3-4 should blow up with every shot).

Follow what happens in the video here and give it a couple of tries. You'll need the second island unlocked and grenades. SOURCE

Sweet!!! cheers hostile that way looks the best.  

I tried the way that video that ganjamonster posted and found that the cars weren't generating below 

Cheers all 

what i did was unlock the  bomb from packie and park a car in a gas station and park 9 other cars in there detonate the bomb and shoot 1 rocket in there just to make sure all the cars were blown up 

ITS PRETTY EASY

BLOCK THE CARS INSIDE THE TUNNEL FROM BOTH SIDES

TRY 2 KEEP SOME CARS CLOSE, BY STEALING THEM AND THEN THROW GRENADES

BINGO!!!!!!!!!!!!!!!!U GOT IT

yeah i noticed this too but all you have to do is get back in the helicopter then jump right back out again and the traffic resumes. but you have to be quickish because they soon disappear again.

good idea starhead im gonna try that 1 as well 

it's a little tricker than it sounds but it's easier than all the other things

LOL i did this one by accident - crashed a wrecked car on one of the bridges, causing a massive pile up, and the whole lot exploded lol

just got the trophy!!!!

What i did was go to the bike shop at weskdyke. Smash my motor through the window and push all the bikes into a corner while in a car (if you get on the bikes old bill is all over you) then park the car im in right up against the bikes then nick another poor blokes motor and park that right against them, then let go with a rocket launcher (3 rounds i think i let loose into them.

Blip!!!!!  Chain reaction trophy

YAY!!!!!!!

Yeah, I'm having trouble with this too. I've stole 12 cars, lined them up 3x4, blew up 8 with the first grenade, and then blew up the other four as quick as I could with the rocket launcher.  Still couldn't get it to unlock.  Maybe it is just f'd up like a few of the trophies and I'm just doing something wrong.  Oh well, I'm sure I'll get it eventually.

Yeah, this trophy is just glitched for me, I'm sure of it.  I tried nearly EVERYTHING, so I went to the bike shop in alderney too.  Pushed the 8 bikes together, had two cars with them, and blew them all up in 8.24 seconds (had my gf time it).  Still no trophy.  Even checked for ten wrecks afterwards in case something got blown out of there w/o exploding, but found 8 blackened bikes and two wrecked cars.

Nvm, I got it.  I loaded up a save from way way back (just in case something got f'd up in all my attempts), and was able to get it at the bike shop in Alderney, doing the exact same thing I did before.  Phew.
