There are 83 challenges available to kill. You must grab 80 of them, obviously leaving you with three 'passes'.
This is undoubtedly the hardest achievement in the game, but far from unobtainable.

Challenges that can be killed:
- 12 Film Challenges
- 19 Hall of Meat Challenges
- 16 Own The Spots
- 9 Pro Challenges
- 9 Death Races
- 9 Thrasher Photos
- 9 TSM Photos
The requirements to Kill the challenge can be found under Challenge Map > Challenges/Completed, and seen by selecting it.
NOTE: You can also kill DLC challenges in order to get this. Credit to JuicyLemurTats for that, which now makes the achievement that much easier.
General tips:
- Getting off your board and sprinting onto it (Hold A + then press Y) is faster than pushing. Use the speed to your advantage.
- Own the Spot challenges are best saved for online - you can jam with friends, whereas the other challenges will require you to both Kill it.
- The Trick Guide within the menus can be your saving grace for a lot of these. If you're not quite hitting the required trick every time, use it! Practice it! It's no good coming close and messing the trick up, that will only frustrate you.
Please feel free to leave any suggestions/problems you encounter. As I've said, this isn't the easiest achievement, so share your experiences.
