I'm doing the road races now, I did the Psych Out achievement last night with a bud. I've got like 4xx Agility Orbs and 13x Hidden Orbs.
Achievements left to do:
* Master Agent - max out all stats
* Timed Stunt Driver - do 6 tricks in 60 seconds
* Orb Hunter - hidden orbs
* Free Runner - agility orbs
* Ring Leader - stunt rings
* Road Warrior - road races
* Confiscator - collectathon, gather all cars in checklist
* Flippin' Crazy - do 3 flips in a jump
* Pack Rat - only available if someone has the DLC content, need to find someone
* Body Armor - only available if someone has the DLC content, need to find someone
I don't plan on buying the DLC, no thanks, so I wont be getting the two Street Racer achievements.
the x means random number that i dont know
