Well, I finally made it to the checkpoint, now I'm working on the train area...
The best way I got to the checkpoint was hiding behind the barrels where the truck is, and 2 terrorists rope down to pwn you. Shoot at the truck to make the terrorists slide down, then own them with a granade, or use your goggles and a sniper rifle.
Then, after that, head to the area where you first snipered the gunner all the way where the light is brighter. Start running towards the steps, then when you here them coming, run back behind the nearest barrels and gun them down. You'll have another gunner to kill of before you make it up the stairs and reach check point... Now your in for another hard mission... the train yard
