This area is driving me crazy, I've tried to dig up to go under the only side of the generators with dirt and you just can't do it.
Can anyone tell me how to get under the generators?
Everywhere else skips that entirely.

Ex."1. Grab the ALM-37 and hop onto the elevator.
2. Ride the elevator up to the next level and take immediate cover.
3. Freeze some enemies with your new gun and smash them with an elbow to the face.
4. Try to find a raptor to take out the turret and keep using cover until everyone is gone.
5 TIP: On the right side of the area there's data cell. Raise the terrain under the metal shed type door and then raise it even more with a spike grenade while you're on it. Jump into the window where it is to claim it.
6. Find the two metal structures in the dirt before the turret and raise the terrain on the switches on each one. This opens a door under the turret.
7. Go down the steps and kill the enemies in the room on the left.
Raise the terrain under the generator and then use a spike grenade to destroy it.
As you can see it never says exactly how to get under the generators.
The platforms adjacent to the generator are see-thru, you can see the ground underneath, you just can't get there.

Please help.

What platform are you on? I got through fine on the Xbox 360.

Xbox 360.
How exactly do you do it? It says to throw a nade up there but they just bounce off and blow up elsewhere.

This is why I need help on this.

I'm still unsure as to what you're actually asking. Could you post a screenshot or something?

I'm not sure how to say it so here's a link (Youtube video) that should help you out for the rest of the level.

Hope it helps! :)
