Shane has found out that the Akurans have some guns and wants you to help him steal them. Head to the mission marker and then hop on top of Shane's truck. As he's driving around, some Akurans will show up, so hurry up and take them out before they start doing damage to Shane's truck, with its health shown at the top of the screen.
Eventually, you'll reach a blockade with a lot of Akurans, so instead of using the precision aiming, go hog wild and start with blowing up the vehicles (which you will need to do anyways). With them out of the way, clean up and you'll continue on to an alley, where you can recharge your powers if needed.
As Shane pulls away, a cop will appear, so quickly take them out and move on. Things might get a little hairy from now on, as there will be cops, as well as the Akurans, all in vehicles coming after you. Don't even bother with focused shooting and just blast the vehicles to quickly destroy them. When you get to the point where a bus comes to block the enemies' path, Shane will pull up into an area and the mission will end.
