Meanwhile, head up the road to the next barricade, watching out for the hoppers that the Combine scanners drop, and the CP in the tower.
You don't have the means to deal with it so let it pass on down the road over the barricade. Back outside, there's a strider over the barricade to the right it'll use its cannon to blow up the car near you. Inside the alley you'll get a medic following you he's useful, so try and keep him alive. Outside the shed, get rid of the hoppers and go down the alley by the rebel who won't follow you for some more health and AR2 ammo.
