Part 59

Destroy the barrel to reveal a vortigaunt (vort) and a grunt. Use altfire hornets to destroy the barrel and then attack them.

Repeat the barrel-destroying and hornet-attacking process for the two grunt barrels further into the room.

Shoot down the visible vorts.

Use your flashlight to see the grunt barrel at the far end of the room and clear it with hornets.

Quicksave before heading to the far end, as there may be more vorts and an alien controller.

Be ready to quickly hornet-shoot and dodge for cover (press the cover button to crouch behind walls or objects) from the controller and any vorts.

Clear the doorway on the left by shooting hornets through it to eliminate the controller and any enemies in the hallway.

Check dark alcoves for supplies like tripmines, C4 satchel bombs, health packs, and AR grenades.

In the hallway past the grunt barrels, set a C4 satchel and tripmines near the first barrel, then detonate to kill the grunts. Consider jump-tossing another C4 satchel behind the second barrel for certainty.

Crouch-walk to the doorway past the grunt barrels and fire hornets at the two controllers, strafing for cover as needed.

Quicksave, then strafe into the room and fire hornets at the two vorts, using barrels and pillars for cover.

Collect the ammo canister to the left of the healing chamber and use the chamber to restore health if needed.

Crouch-walk through the three small holes in the wall to the left of the healing chamber to load section c4a1e.

In the huge shaft area, approach the shaft on the left and carefully drop from top-level bars to mid-level bars, then low-level bars, and finally to the shaft floor.

Crouch-walk into the tunnel in a corner and move until you reach two holes in the wall with drop-downs.

Move to the right hole, equip the gluon gun, and quicksave.

As soon as you drop down, turn right and run along the ledge to the back, hiding behind a large pillar from nearby vorts.

Quickly blast the three alien controllers with the gluon gun as soon as you see them, moving on the ledge while avoiding vort attacks.

If controllers charge and vorts zap you long-distance, get behind the pillar ASAP and blast any zapping vorts.

After dealing with the initial enemies and controllers, kill the two vorts coming along the walkway with the assault rifle.

Quicksave, then peek out and use the hornet gun to take down any visible nearby vorts, including those on spinny lifts.

Switch to the hornet gun and stand behind the pillar to kill the vort on the nearby spinny up-n-down lift.

Move to a position where you can fire hornets up at the nearest higher floor with a grunt barrel to kill the vort there.

Jump up and down near the pillar to see if you can hornet-shoot a vort on the walkway just above you.

Start moving along the ledge that goes around the area.

Keep an eye on the floor with a grunt barrel.

When about halfway around the ledge, you will see a dark recessed area with two small pillars under the barrel's floor.

A vort is hiding to the right of the right pillar; sneak-shoot it with hornets or the crossbow before it sees you.

Use the flashlight to watch it carefully, as it may run onto the ledge or go up to the barrel's floor.

Quickly use hornets or the .357 to finish it off.

Enter its dark recessed area to find a ramp leading up to the grunt barrel's floor.

Once on the barrel's floor, prepare for the vort on the next spinny up-n-down lift and two vorts on the walkway above.

Get to a position where you can see and hornet-shoot the vort near the grunt barrel at the top of the lowest spinny up-n-down lift by jumping up and down.

The second vort above will likely have to wait, but look for it next to a barrel near the top of the second spinny lift.
