Stuntman: Ignition

This achievement can be kind of misleading, the first time I was trying to do it I thought the achievement was glitched or broken, but thankfully I was just confused.

From the main menu select the "Constructor," then select "Freestyle Arena" now select any one of the up to three arenas that might be there.

Now you want to go to edit arena and begin building a nifty little stunt course for yourself. In order to qualify your arena for the leader boards you want to have as many different objects in the arena as possible. Getting on the leader boards has nothing to do with getting a high score, Just place one of every single prop that you have available to you in your arena until you fill up the arena capacity bar. Once you are finished Push start and select "Qualify Arena"

Now drive around for 30 seconds doing basically whatever you want, just play around and make sure you are actually playing for the 30 seconds and at the end if you had a large enough variety of objects in your arena you will be put on the leader boards. Select yes when it asks you if you want to be loaded on the leader boards. Skip the cut scene and simply select "Qualify arena" again and do it 9 more times for the achievement.

Where I got confused was I thought to get up on the leader boards you needed to get a high score in the 30 seconds, but really you just need to be the one with the largest variety of objects in your arena. The score you get has pretty much nothing to do with qualifying, you just need to prove to the game that your arena is playable by driving around and interacting with objects for 30 seconds.

Finally the leader boards reset each month so if you can't get it for whatever reason it becomes much easier during the first week of the month. As well you can unlock more objects to place in your arenas by getting 5 stars in different "constructor challenge" events which you need to do anyway for another achievement.

go to constructor then...All you have to do is create a stunt that can have you playing for atleast 30 seconds. You need to put every single object you have available.Do so until you have filled the bar on the left all the way press "Qualify Arena" make sure you get the ""submit arena to the leaderboards" press yes.

Now after you have done that you should get the "Entertainer" achievement don't exit just press qualify arena you should get the same message, then basically repeat it 10 times and thats it:D
