Map 1[edit]
The new chapter, the same goals. If you make a few steps and look left, you will see an easy snack tinkering with an elevator. When you proceed ahead, doors will open and a heavy guard will walk in. You can smash the circuit box near the double doors but that won't do a thing.
Climb up where the elevator shaft is. If you emerge being too careless, you will be attacked this instant. When you're done, enter double doors, smash the grille on the ceiling and get into the vent. Follow the long red tunnel until you come to another smashable grille.
Destroy the grille, drop down and kill two guards. One of them is really close to you, he won't be a problem. Another one will cause you trouble if you're not fast enough. Don't forget to destroy the sentry gun control panel near the second guard. Since one of the doors is broken (it's stuck and you can't squeeze through), follow the opposite way until you come to a room #4 (see the big 4 on the second floor) with stairs leading down into the generator control room.
Jump down and pretty soon you will come to a room with the generator itself as the sign was telling. You will see a harmless scientist who seems to be an easy prey. Well, he's not. If you kill him now, you will be killed by a synthet from behind. The synthet is hard to spot because he doesn't emit pheromones. Kill that foe first, he's in the corner. Then bite off the scientist's head and smash the control panel.
Go back to the previous room and you will be attacked by two soldiers from the second floor. Kill them, turn left and follow the ramp. Another soldier will be heading towards you but there is a chance that he won't see you until you come too close. After killing him smash another sentry control panel. At the end of the ramp there will be a synthet. You can kill him or you can avoid him. His head can't be bitten off anyway.
You will arrive in another big room. If you want to ignore it and proceed ahead, then skip this paragraph. One human will be tinkering with an elevator control panel, he's an easy prey. Another one is patrolling the upper floor, but he's harmless either. If you kill both scientists, watch your back, soldiers will appear from behind.
If you killed all the humans or decided to skip the room, go to the next one, the tunnel to it is opposite to the one you used to enter the room. There's another room #4 whatever it means. You will hear a skirmish and when you arrive, some humans will be already killed. Do not put good food to waste and bite off their heads.
Climb the walls – the path out of the room is at the ceiling. There you will see two guards going somewhere and not minding you. Despite they are good armed, they won't be a big problem.
The tunnels look huge, but there is a single way to follow. When you arrive in the next room, there will be two armed humans on the ramp to the right. Try to reach them before they can spot you. You're on the upper floor now. Follow the ramp until you come to a broken wall and turn to the tunnel. Sooner or later you will come to a room being trashed by a predator.
Boss fight: Another Predator
It's not easy to come closer to this foe since he's constantly firing his shoulder cannon at you. Try to stay out of his sight and always move when he sees you. When you come close enough, the predator will take out his combistick and try to stab you. From now on the tactics is the same as with the previous predator at the end of chapter Escape.
Look for a broken pipe with a smoke coming out of it and climb in. It's not easy, sometimes the game may glitch but once you're in, crawl ahead and you will come out in a room with some toxic green goo. A human guard is not minding you, so make the best of it. Go out the open doors.
Map 2[edit]
You will see an elevator going up. Smash the broken fence and crawl in. Now you must ascend but there are some tricky parts. There are enemies on different floors. Once they see you, they will start shooting. Save before going up to know where it's best to ascend. The first floor you will appear on contains two guards, the second one contains two turrets.
When you climb to the elevator bottom, you will see a vent grille. Smash it and get inside as you always do. Follow the vent until you come out. Humans have taken away the Empress and locked the door behind. Follow the tunnel and look for a grille to the right near the wall. Smash it and follow the vent until you come to some technical room. One heavy soldier might cause trouble but two scientists will allow you to heal yourself.
Follow the corridor and you will see two soldiers. Kill them from behind and get ready to be attacked by another soldier who will come from ahead pretty soon. When the enemies are done with, follow the winding tunnel and get ready to face two more soldiers after you take another turn. After them there will be a solitary soldier with his back to you. When all enemies are killed, follow the path until you come to a dead end and smash the control panel on the right.
The door is open now. If you go straight ahead, you will appear in a room where you exited the vent. Turn right instead, enter the room and smash the control panel there. Go back, turn left and pretty soon you will see an open door to enter. Follow another corridor and you will come to a room similar to one you've recently destroyed the control panel in. In the new room destroy another control panel. A guard will appear and most likely run away from you.
Find the main winding tunnel and follow it. Careful! After destroying all the control panels there will be damaging steam, so try to avoid it. Eventually you will come to open doors with two synthets guarding it. Destroy them and head in. Smash the grille and follow the vent.
After killing a scientist you will see synthets fighting a predator. The predator will win. Now you must destroy four boxes marked from C1 to C4. Two light-blue dashboards look like they are interactive but they are not which is confusing.
After you're done, head back to the vent. In the corridor you will face a soldier. One more soldier is waiting outside the next corridor. Go straight ahead through double doors to end the level.
Map 3[edit]
Climb the pillar to appear on the landing pad.
Boss fight: Predator Bros
The first predator is waiting for you, the next one is watching from above. You can't reach the second predator and he won't attack you for now. Get rid of the first one. The strategy is the same as with all the previous predators. When you kill the first one, his brother will come down to avenge. Kill another predator. Sometimes the game glitches and the second predator just stands and does nothing.
After the fight the door will open and a guard will come out. The next steps are pretty simple: kill the guard, go in, smash the grille and follow the vent until you come out in a corridor. You will be instantly attacked by two guards from a control room on the left. Smash the "LANDING BEACON CONTROL" panel. You can backtrack to the beginning of the level now or you can watch how the dropship is trying to land first.
Boss fight: Eisenberg
He's a joke as a boss. He has low health, one pounce is enough to kill him and he can be beheaded just like a human. The quickest and the easiest way to kill Eisenberg is to pounce on him when jumping over the gap.
