Part 44

Use the sandbag wall for (cover (press the cover button to crouch behind walls or objects)) when enemies try to zap you. If they hide, look for them in the side niche next to the ramp where you blew away a vort earlier.

Go back and get the security guard to follow you again.

Lead him down the big ramp and past the whoosh-thing to the little security booth.

After he opens the booth's side door, get him to follow you again. Quicksave (checkpoint (an auto-save point you restart from on death)), then go through the door and down the winding corridor to where section c2a5g loads.

As soon as section c2a5g loads, start running. When you exit to the parking garage, turn right and keep running without slowing or stopping.

If you make it outside fast enough, the gargantua probably won't ever come outside after you. To confirm this, turn around as soon as you make it outside and go back to where you can see the gargantua in the distance. It should still be standing behind a parked car, and your security guard will probably be shooting at it. If this is the case, turn around and go back outside, secure in the knowledge that the gargantua can't follow you out there. If that's not the case, restore the quicksave you made right before entering this section and try again. If you're fast enough and never get snagged, it should work for you eventually. Note that returning to check on the gargantua might free it up to follow you when it otherwise wouldn't, so try skipping that step if nothing else works.

Once you're outside, find the alien whoosh-thing on the ground and use it to jump over the wall and fall into a water tank.

Jump onto the edge of the tank, then crouch-walk carefully along the narrow pipe that goes up to a point near the top of a waste silo.

Jump-crouch onto the silo's top to find several health packs and a military targeting system (a device to call for missile strikes).

Use the targeting system's two levers to target the large doors in the very back left corner of the area (top left on the targeting map), then use the central button to call the missile strike. Once those doors are blown up, you're through with the targeting gadget.

Drop carefully onto the slanty pipe and use it to return to the small water tank's edge. (Or take a running jump over the pipe and into the water, then hop up onto the tank's edge.)

Move along the edge until you're next to the wall, then jump-crouch onto the wall.

Turn right and go along the wall and across the big gate until you reach the slanty part of the area's outer wall.

Jump onto the bottom part of the slant, then move along it until you can drop down onto the slanty bit of concrete that's on the left side of the blown-open doors.

Quickly drop to the ground and run through the doors before the air strikes start up.

Alternatively, after blowing open the doors, you can reset the targeting gadget to aim at the gate the gargantua will break through to blow it up when it shows up, or quickly blast the other two things needed to escape (leaving the gargantua behind). The other two targets are the wall to the right of the blown-open doors and the two large electrical boxes to the right of that, next to a small radio tower. The radio tower is the hardest target. You'll know you've got it when the radio tower falls over. Use the concrete ramps next to the silo to get down to where you can jump onto the fallen radio tower, then run across it and jump over to where you can run through the blown-open doors.

Run down the large tunnel until you turn a corner and find some side stairs to go up.

Go around the corner past them to finish this chapter and start on "Forget About Freeman!".

In the room ahead, run through the gap in the railing on the right, then run down next to the spot where the first large chunk of ceiling falls down.

Jump-crouch onto the narrow ledge next to that chunk, then jump-crouch onto it and crouch-walk over it.

Move into the large control room beyond to be safe from the falling rubble.

After all the shaking around stops, jump-crouch into one of the large windows, then move forward to drop into the area beyond.

Turn right and find the red railing. Practice running up to the railing and jumping over it until you can do so quickly and easily. That's your way back into the control room after you get the attention of the aliens in the area ahead.

Bash the crate next to the security guard to find a health pack, then get the guard to follow you.

Go over to the right side of the large opening that leads into the big room with the crates in it, then get out the crossbow.

Crouch-walk forward to where you can sneak-shoot the alien grunt that's around the corner and to the right of the wooden crates. Kill him quickly, before he has a chance to run around or see you.

Back off a bit and use the hornet gun to destroy all of the wooden crates.

As soon as the vort that was hiding behind the crates sees you, turn and run for the railing.

Jump over it, then turn right and run into the control room and crouch down.

Stay crouched as you move over to the switch on the wall (or the keyboard on the table) and use it.
