Just make sure you alway take a jeep with a turret on the back. Drive through the guard posts at full speed and if the enemy catches you and you need to stop, hit "C" to switch from driving to the turret. Then proceed to blow their brains out, fix your car, and continue on.

Yeah you should do weapon dealer missions to unlock the MAC-10, combining it with the sniper rifle is a good combo, the pistols are kinda useless when you're surrounded. Also you can get more sniper ammo in an upgrade later on.

Actually, I find them very entertaining. Believe me, once you get farther with better weapons and the second half of the map, you'll find it fun to plan it out--should you spread fire throughout the area (the southern map is WAY better for burning), blow everyone/thing up with the GL? snipe everyone with the 50 cal? Mortar it? it's pretty fun.
