Here is a list of objectives that count toward this achievement:
Vehicle Stunts - These are the purple dots on the mini map. For the achievement you only need to do one, so go find an easy one then take a fast car and make the jump.
Glider Stunts - These are the green dots on the mini map. To do these you need to unlock the wingsuit (Lvl 5 Agility). Simply glide through all the green dots to complete this.
Absorption Unit - Will unlock during story
Beacon Activation - Will unlock during story
Rooftop Race - Go to a green flags and finish the race
Driving Race - Go to a purple flag and finish the race
Freak Breach - These are only available in an area after you activate a beacon. They are the yellow splatter marks on the mini map and are only open at night. Go to one and kill all the marked enemies
Orbs - You have to collect at least one of each type of orb (Agility, Renegade Agility, Driving Agility, and Hidden). I dont believe the Online Orbs count.
