I'm trying to do the grand central mission for operation sandstinger but I'm stuck at the console part. Theres a dude at one of the console who literally dies after 5 rpg shots and the railguns can shoot you when you are trying to access the consoles. I can't do operation sandstinger because of this.
OK, here's what you do: Go back to the mission and when this part comes, go to the turrets. Grapple a few cables to them to keep the turret from turning and shooting at you and then look closely at the turret. There should be 1, or 2 panels on them that are marked with an X. Grapple those panels off and shoot at the parts inside. This should blow up the turret.
And it just has to be one of the 2, or 3 missions that I did with out making an article for them. I guess that something I'll have to do the next time I'll replay the game.
