Stuntman: Ignition

You should get 15+ of these simply by playing the campaign. but if like me you hadnt got all 20. simply load up the level UNSUNG HERO" on the strike force omega levels and there are 3 oppurtunities to get an over take on this short level taking just over a minute to complete.. i can confirm you mustt finish the level, not sure about failing but you wont any way its an easy level.
The other good thing about this level is its a nice speedy level and also you can boost the 30 ," 180 turns if you havent got that also. T his guide i hope helps u save time looking for a level to do this one.

An Over-Take stunt is when you are told to overtake a vehicle before it gets to a certain point in the level. There isn't a specific place to try this because it's an achievement that should definitely be gotten through the course of you playing through the game.

To get the achievement you need to make sure you get to the end of run for it to count. It also may be possible to get it by purposely failing the level afterwards but I can not confirm this.
