Mission 5 - Fallen Angel - Story progression achievement, cannot be missed.
This mission might take you two attempts to complete the challenges due to the end with the vehicle pursuit. You will have the option to drive the SOC-T or fly the drone.

The second one is located after you head through the big building where you have to take a series of left turns. The jump is a dirt ramp that launches you through a window and through a building. You will need to hit the boost near the top of the ramp to make sure you have enough speed.
7) Destroy 20 enemy vehicles withe drone missiles - Challenge 7 and 6/8 cannot be done at the same time. You will be given a choice to play as the Drone or drive the SOC-T. If you choose the drone, simply destroy 20 vehicles in the escape scene of the mission.
