Do not confuse this chapter with Surprise. They are all called Escape when the level is loaded. For the Surprise chapter see the previous page.
Map 1[edit]
Go down the tunnel and kill a human who's installing the turret. Lucky for you, the turret won't fire so you can easily destroy it. Let this be a warning for you – turrets nearby!
The road ahead is blocked, so turn left and kill two guards. Going through the door will result in certain death from turrets, so climb to the grille, smash it and go through the vent.
Note: You can rend wires near the fusion boxes to stop fans.
Go to the next room through the vent. Stop fans and drop down. Three soldiers will attack you. When you finish, go back to the previous room, but use the main corridor now instead of a vent. There you will find a pile of crates. Two turrets are behind them and one in the corner, all can be destroyed while you're staying in blind spots. To through double doors and kill two soldiers instead if you want to but that's not mandatory.
Red glow in the corner indicates a vent that can be accessed by smashing the grille. On the first turn climb up. After you arrive in a tall structure, climb up again and through the vent. When you smash the grille, you will hear human voices commenting your actions.
You can drop down and kill all humans which are 5 total but less straightforward tactics recommended. Because of a huge size of the room you're in and its emptiness it's harder for you to get closer to your victims as well as easier to sneak and avoid detection. You can just jump into the water and search for a red glowing. That's the vent you need to reach. Break the grille, go in, right, up and to the next room.
This time you will be 100% spotted by two guards. Lucky for you, they both have pistols so they won't do you much harm. A scientist is hiding behind the first huge non-working fan. Walk behind the fans and into the vent. When you appear in a technical space or something look for two fuse boxes and smash both. Return back.
Go ahead to the double doors. There is turret aimed at you but if you pounce on it from the distance you will destroy it before it starts shooting. Proceed ahead until you come to a room with closed gates and a ladder.
Look for a ladder up and climb it. There will be a scientist behind a non-working turret and wires that need to be destroyed. Climb into the vent and head to the neighboring room. There smash two wires, jump down and kill humans which are 2 guards and 1 scientist total. Or instead of climbing the ladder you can just turn into that room directly.
Map 2[edit]
Smash the grille and kill a guard on the elevator. Now you need to head down. Use the wallwalk or just jump, you won't receive damage from falling. Two heavy soldiers are on the elevator below, so if you land behind them, you will easily deal with them. Or just avoid them. Your destination is the ground floor where you'll meet a guard, a civilian and a non-working turret.
You will come to a T-junction and will have to travel through a set of big corridors fighting humans. They can be a menace at long ranges, but remember that you can lure them out or reduce the distance with pouncing.
Look for a corridor with two turrets facing you. Don't worry, they are not working. Gates nearby will open letting a few humans out. Get rid of them, go to where they came from and jump down in a tall room where a single enemy awaits you. As you might have guessed by the color of his pheromones, this is no human.
Boss fight: Predator
According to the plot, each predator was trained to fight a horde of aliens. Now a single alien must take down a predator. You tail attack and headbite won't work on him. Your pounce will still deal a great amount of damage but won't kill the foe with a single hit. Luckily, the predator is slow and has no ranged weapons. There are no special tricks how to kill this enemy quickly. Quickly backpedal after pounce and strafe after a regular attack.
When you kill the predator, he will activate a self-destruction just like in the movie and that's the only time in the whole game where a predator self-explodes. Quickly climb the wall back. There are a few safe spots nearby in the room where the explosion can't get you but they are not easy to find.
After the explosion head back and you will see an open door. Go in and turn left. In the room follow the pipes to exit the level.
