Gain access to the Predator Temple
The game will start in the corridor, near the temple. Go outside and take the path with some predators statues [#325]. When you will get to the bridge jump to the other side and activate the stone mechanism [#326] - you will see many of these devices in this chapter.
Turn right and when you will get near the abyss - look down. Jump on the shelf [#327] and activate another mechanism [#328]. In this moment aliens will be coming out from the pipes. Wait for your enemies and kill one after another (watch out the cliff).
After dealing with Xenomorphs take the narrow path [#329]. Get to the stone bridge and jump on the shelf with the last mechanism [#330] in this part of the chapter. When you will activate it the gates to the temple will be open.
Go up and kill the next group of Xenomorphs that will come out from the building. After dealing with your enemies, use your first aid kit and enter the temple [#331].
Recover the ancient Predator Mask
Now it will be more difficult. When you will enter the hall you will see some stone blocks [#332]. You must use these platforms to get to the top. Some of these block will be hiding after few seconds so focus on that.
When you will be at the top use the next mechanism located there [#333]. The next door will be open - go there at once.
Get close to the mask [#334] and watch the short cut scene. After a while you will see that ghosts of your ancestors had appeared in the room. One of them, the boss of this group, will throw an alien body on the ground. Wait until the end of this movie and get out of the temple (use the exit located on the left [#335].
Locate the Missing Artifact
You will find yourself in a huge cave. Change to vision to the alien detection. The bodies of your enemies will be shown on the screen as green objects [#336].
Go straight ahead and observe the area - after a while you will be attacked by an alien. From this moment you have to be very careful. Prepare for next enemies. Xenomorphs can attack you in almost every moment.
Start jumping on rock shelves [#337] and kill some aliens. During the battle only defend yourself - do not attack enemies that are not attacking you. Be careful and try to stay away from the edge of the cliff.
When you will be near the stone bridge [#338] aliens that are able to spit with the acid will appear. The only effective method is to kill them from the distance. Use your plasma caster o disk. Then go to the other side of the cave.
Proceed to the research lab to recover the stolen Wrist Bracer
At the end of the bridge you will see a dead body and the transmitter. You will learn that your artifact was transported to the Research Lab. Jump on the shelf located below [#339] and go straight ahead. After a while you will find yourself in another cave [#340].
Go according to the marker and eliminated every alien [#341]. Most of the Xenomorphs are spiting with acid so use the plasma caster or the disk.
After a short trip, you will find yourself near the stair. Three soldiers will appear. Turn on your cloak and eliminate them [#342]. Door will be shut now but there are no real problems for a such experienced predator as you. Use rock shelves [#343] to get upstairs and activate the mechanism [#344] to open the next door.
You will find yourself in the first part of the ruins [#345]. On the other side, you will see a ship wreck - the same that was shown in the first campaign. Soldiers that are fighting with alien will go back to the building. After a few second Xenomorphs will attack you.
This area is guarded y two turrets. First of them is located near the main entrance of the building [#346] where you are standing. When you will sneak inside you will be able to kill your opponents and disable the turret using the computer [#347]. The second turret is located near the huge predator statue [#348]. You can ignore it.
To get to the other part of the base get near the wreck. During the trip you will have to kill a large group of aliens (normal and acid spiting ones). After the battle, get lose to the wreck and jump on the shelf [#349] where you will have to use another mechanism [#350]. You will gain access to the next part of the ruins.
Locate and activate the 3 species symbols switches to open the exit
If you had completed two previous campaigns this area will be very well known to you. You have to find three opening mechanisms in the labyrinth. Two of them - [#352] and [#353] - are located on the lowest level. The third one is near the closed gate [#354].
This terrain is patrolled by a huge number of marines [#351] that's why you have to kill some humans first. Without your enemies looking for these devices will be much more simple.
When you will turn on all devices go to the open door [#355]. Kill the soldier and then jump inside the building.
Survive the trial by combat
Now it is the time for the last trial in this chapter - you have to fight with the Queen on the arena [#356]. Go to the marked tunnel [#357] and recharge your energy with some power nodes. Go down using the stairs and jump to another tunnel. As a matter of fact, you will find yourself in the arena with the Queen.
Alien Queen will appear on the battlefield [#358] (she will be with her children). In the each phase of the battle two Xenomorphs will defend her mother. So if you will kill one of them soon another one will come.
The main target is to kill the Queen - her health bar will be shown on the screen. You will find out that close combat doesn't make sense here. You will be killed in one shot. In addition other Xenomorphs will attack you.
To deal with the Queen you have to attack her from the distance. There are many pillars on the arena. Use them to separate from your enemies. When you will be at a log range she will start to spit wit acid but this much better that her claws.
When you will be near the pillar start to attack with your plasma caster [#359]. Each shot will take huge amount of health from your opponent but you won't be able to kill her with this weapon. You can regenerate the power using the power nodes or kill he with your disk.
During the fight Queen helpers will try to attack you. Kill them immediately with your writ blades.
After the battle jump on the highest pillar and then on the balcony [#360]. Predator will gain a spear - the most powerful weapon in the game.
