Burnout Paradise

This achievement requires either both the Burnout Paradise 1.6 Update DLC (which is free, has been updated to 1.9 now) and the Party Pack DLC or the Ultimate Box version of the game.

From the main menu, select Start a Party. Make sure it has 2 players then hit start to continue to the number of rounds screen. Make sure it has 1 select, BUT BEFORE HITTING START TO START THE PARTY hit down on the LS to highlight where it says Random and change it to Stunt. The stunt events are the only events that everyone can score on in the same round. Now hit start to continue.

There are a large variety of stunts that the game can have you perform, all the way from extremely easy to nearly impossible. Hopefully it gives you one of the easy ones. To get the achievement, both players need to complete the stunt. If it gives you an easy stunt, this shouldn't take long at all.

The simplest way to get this achievement is to Start a 2 Player, 1 Round stunt match in Party Mode and just make sure to score on the stunt given with both players. You only need one controller for this achievement. Should take 2 minutes. If you somehow stink at the stunt given, play another match and hopefully you will receive a different stunt that you excel at.
