Part 12

As the Centurion approaches, it will grab onto your cage, causing it to fall and initiating the boss fight.

The Centurion attacks with swipes and two AutoCannons, which have standard machine gun fire and a grenade launcher function.

Use the pillars in the room as safe areas to find rifle ammo and health spores.

Use the pipes as cover (press the cover button to crouch behind walls or objects), as they absorb AutoCannon fire.

When the Centurion pauses firing, pop out from behind the pipes and throw a Crawler (if you have any) at the beast. Switch Crawlers to proximity mode using the Left Trigger so they stick to the Centurion.

If you don't have Crawlers, use another weapon in the same manner.

If you run out of ammo, step out into the open to find more rifle ammunition behind another set of pipes.

Fodder enemies will also appear; they are a distraction.

Continue attacking the Centurion until a previously forcefield-blocked area opens.

Run across the room to the opened area and hide in the corner.

When the Centurion approaches, stand by the touch screen monitor that activates the forcefield.

Wait for the Centurion to stick its hand in to attack, then use the touch screen to activate the forcefield, severing its hand.

Retrieve the AutoCannon.

Equip the AutoCannon and continuously fire at the Centurion while hurling grenades with the Left Trigger.

After defeating the Centurion, an orange portal will open. Step through it.

In the next area, encounter Hunters, some of whom throw explosives.

Move to the end of the area and use your alien hand to activate the panel to the right of the wallwalk behind the forcefield.

Follow the wallwalk around; Hunters will spawn on the floor and in your path. Kill them and continue.

At the end of the wallwalk, use the alien hand to open the door via the identification panel.

Proceed to the area with the large, spinning blue portal.

Use the touch screen monitor in the middle of the room and fight off Hunters and Hounds.

Once the room is clear and enemies stop spawning, the blue portal will straighten out. Step through it.

Ignore the Harvester enemy and move forward until you hear Enisi's voice, ending the level.

Follow the path to the fireplace and speak to Enisi.

After the conversation, follow the path to the spirit cave.

Inside, you will see a holographic representation of Jen.

After another conversation, you will be transported back to the alien world, ending the level.
