| [Tutorial] GTA IV - Chain Reaction Achievement Chain Reaction - You must blow up 10 vehicles in 10 seconds. 20 Gamerscore This achievement is kind of glitchy becuase people have done this numurous of times over and over and no achievement. Personally it's my 3rd time i did this and have finally got it. When i did it the first time it was at the begining of the game but i didn't have grenades so i cheated now the cheats don't disable it so i should have worked but it didn't so i don't know what went wrong but when i got grenades and got the cars it worked. Plz leave good comments and ratings. Tags: [Tutorial] GTA IV Chain Reaction Achievement Grand theft auto Rave new world |
