Grand Theft Auto IV

Grand Theft Auto IV Achievements

Chain Reaction

You must blow up 10 vehicles in 10 seconds.  

Go to a local ammunition supplier and obtain some explosives, the rocket launcher and standard grenades work the best. Once you have these, choose anywhere in town that makes you happy, preferably somewhere busy. Go into the road, steal a car, and park it so that it blocks traffic. Then steal another one and make the pile of cars bigger. Once you have at least 10 cars in a big pile, start detonating them, and then any surrounding cars until the achievement unlocks. 

**Can be done after completing story mode**

Here is the achievement in action by way of a slightly different method:

Thats really easy if you have The Ballad of Gay Tony.

Find a narrow street (I did it near Brucie's place) and take two cars to block traffic (park them in the street sideways, one for each lane). Then box up four cars on either side (2x2). Then using a rocket launcher, fire off shots at both ends and the middle. The explosions should get the neighboring cars if you pack them close enough together.

Go to Star Junction and get a bus. Then drive over to Broker Bridge and block the oncoming traffic. Climb on top of the bus and throw some grenades once there are 15+ cars blocked. (15+ so you won't be forced to blow them all)

There is a parking lot, with cars parked every other one, in Industrial, Bohan. I parked cars in the empty spaces until I had 6 cars in a row. Then I parked some behind them to get to 10. One rocket in the middle and they all went up.

Isaacthegamer's hint helped me get this. To find the parking lot easier, just go to Industrial Bohan, kill yourself, and you should spawn at the hospital west and nort of the strip club. Turn and look south and you should see the lot on the opposite side of the street, a couple hundred feet from your spawn spot.

I was kinda pi**ed because the police always screwed up my gathering of cars ("ooooh, you do not steal this car, baddie!") and due to (re)spawn of the street blocks I was hardly able to build up enough cars in the pile to get this achievement. After getting the "Walk Free"- and "One Man Army"-achievements, I used the "Remove Wanted-Level"-cheat (267-555-0100) which works, even if the cops stand beside you, and had no problems building a pile of cars at Star Junction and was able to blew it up with just two grenades. As for this cheat blocks the two mentioned achievements only, it makes things a lot easier, if you are desperately trying to blow up some vehicles and not being disturbed by the cops.

You can get this one very easaly in the version Ballad of Gay Tony. In this game you have sticky bombs. Just throw 10 sticky bombs to 10 different cars and let them explode all at once. Youll get your achievement immediately!

For this one, I went to the gas station and gathered up a bunch of cars without getting too far away from the area. Then u just need to park/pack them tight. Then i used my RPG to blast the gas station and remaining cars.

Take a large car and head to a petrol station. Block the exits and wait there for the cars to pile up and get impatient. They'll ram themselves in there, creating more space for other cars. Then all you have to do is blow them up with an RPG, (not a grenade because the drivers will have time to attempt to escape).

Friday, September 30, 2011 @ 06:48:59 AM

this is bullshit, i definity blew up 10-12 cars within 10 seconds over and over and i just never get it ?

Tuesday, October 11, 2011 @ 03:30:41 AM

Okay I just found the easiest way possible to get this achievement. Keep in mind you will need TBOGT do pull this all. It's simple, all you have to do is block off track on one or both sides of the street, start pointing your gun at the driver as this will make most of them jumped out right away and even if they don't they likely will bail out close enough to you, second step start rigging cars with sticky grenades (i rigged a couple more than ten just for good measure, detonate using your remote detonator from a save distance, and pop! The achievement is yours.

Do any cheats affect this achievement?

I've tried doing this achievement so many times and have clearly done it more than once as my method is one of many used. The only cheats I've done is Lower Wanted Level, Weapons Tier 1 and Comet Car. Using these cheats I've managed to get a load of other achievemets, bar this one.

Someone help me, many thanks.

Using the video guide worked perfectly for me first time! Its really straight forward, I literally landed my helicopter, jumped onto the ledge and started shooting rockets out, got it within seconds!

Comment #37 by K1nG JaY xX
Monday, September 03, 2012 @ 11:03:33 AM

Ya it's easy, I did it first try, go to a sorta busy area, look for somewhere that has a boxed in look with one side open like a garage, pile and count 10 cars, leave the doors open when you park em once u get 10 throw a grenade in the middle or under the first car and boom achievement, try to keep from using cheats, i'm not aware that any block that achievement but glitches happen.. Good luck to everyone

Comment #38 by BriceXD
Wednesday, October 10, 2012 @ 07:21:39 PM

yep, same deal. #23 comment has it figured out. Go to the bike shop, push all the bikes together with your car, add a couple cars to the mix, and one rocket, and viola

Go to the prison car park on the 3rd island with an rpg drive into some of the cars so that they are closer together and then just shoot them with a few rpgs and tadaa!

Comment #40 by rheddpheonix

Cluster up a bunch of cars, and then toss grenades on the far-side and middle of the group and blow up the side of the group closest to you with a rocket launcher.

I did 14 in 5 seconds and it didn't unlock.

Tuesday, July 09, 2013 @ 08:47:23 PM

I used the #38 method, but i got on all the bikes and drove them to the corner, does that make a difference?

Comment #45 by Shane724
Sunday, July 14, 2013 @ 10:06:19 PM

Using cheats disables this one, I had to get arrested, shut off my console, buy weapons, then blow up the motorcycles and it unlocked.

Comment #46 by Wolfwood NLB
Wednesday, August 07, 2013 @ 11:49:11 PM

Thanks @#45, that worked for me. Although it says "Cheated 0 times" in my stats, I thought I may have used one early on, so I got arrested (didn't turn off my console though), went to the gunshop and got 8 RPG rounds & body armor, then went to a car dealership and bam! Easy as cake (like it had been all along, I just didn't know something was blocking it). Then of course I dashboarded out since they took all my weapons AND that cool ski mask I'd been wearing since the heist mission.

this one was pissing me off too. but they i went back to play the "deal" mission at the very end of the game. when you chase the suv to where pegorino and the russian guy are and you tell roman and jacob to leave. kill all the guys outside(very easy) they have 7 cars, and you came in one. run up the hill across from the warehouse to the highway and steal 2 more and park them all bunched together. climb up the hill to the highway again, and shoot 2 rpgs. that's probably the easiest way i can think of without the cops coming after you.

Sunday, March 23, 2014 @ 02:16:00 AM

I got this with on rocket & in first try by using the Motorcycle shop solution suggested by #23 just pushed the MC's close together (using the car)& as an insurance parked 4 cars around them,think the trick is to pack them tight so one explosion more or less takes out them all...
Oh,had a little problem finding the MC Shop but just find the Burger Shot that's the longest to the North West of the map & then follow the road leading south from there & you can't miss it,it's on your left...however that Burger Shot seems to sometimes disappear from the map so should that happen you can find it by using the 3 blind roads that's in the North-Eastern top corner off the Alderney Island,where the 3 blind roads become 1 & connects with the rest of the city you'll find the burger Shot,good luck :)
