This achievement can be a little glitchy because a friend and I did the same thing 3 times and it finally worked on the third attempt. What you need to do is for Level 3 make sure you destroy all of the engines (these are the things with bluish fire spewing from them) and then on Level 5, make sure you DO NOT destroy any of the targets on the ceiling. You can damage them just do not fully destroy any of them. If you do these two tasks and then go on to beat the game, you will then unlock this achievement. UPDATE: Also, make sure you also do not pick up the booster at the beginning of level 4 (the booster is the thing at the bottom middle of the screen when the level starts).
