Aliens vs Predator is a first-person shooter developed by Rebellion Developments and published by Sega. In the mission Jungle for the alien, the player will have to infiltrate the marine base, sabotage an antenna and destroy the security computers to blind the humans in order to strike.

1. Go down the tree and enter the vent on the right side of the closed gate. Exit and kill the two soldiers. There are two gun turrets at the center, go between them and destroy the control. Then, head to the wall with the power box and destroy it to shut down the electrical fence. In the small room where the power box was, enter the vent and exit outside.
2. You now have to sabotage the antenna. Go to the right of the area and stick to the wall. You will soon see a bunker with worker inside and outside the building. Harvest the one outside and continue to the antenna. Climb the wall just next to the buiding with the antenna. There are two guards there. Wait for them to split up and quickly kill them. Two more might arrive so be alert. Locate the antenna, climb it and destroy the panel.
3. Three marines will then arrive. They will first check the building with the worker inside and then go to the camp you first arrived. Wait for them to check the camp and attack there. Run and hit quickly. The three marines always stay together so you have no chance for stealth kills. Be fast and hit them quick. Two of them have flame thrower.
4. Then, follow the marker on your screen and enter the marine's base. You have to find access to the building with a worker inside. To get in, look for a vent around the building and use it to get inside. Harvest the worker and go out. Now, you have to access the building on your right. There is a soldier inside and the door is already opened. But, as soon as you enter, the marine escapes and lock you inside. Before more come, destroy all the lights in the room and wait behind a shelf. When the first enemy enters, wait for the right time, run tom and hit him as fast as you can. Then, quickly retreat.
5. There is one waiting for you at the door, run to him and perform a Heavy attack to stun him, followed by a instant kill. Take care of the last marines on the base.
6. Now, head for the two generators and destroy the power boxes. Head for the second floor of the building marked with on your screen, enter the room and open the door. Go down a level, open the door and kill the marine inside. Use the vent on the ground to access the next room. Two marines will arrive in the room. Use the vent around the room to hide and wait for the right time to kill them. Hiss to lure them away. 
7. Go to the next level and wait for the guard to come out. Attack her and get inside. Approach the worker but quickly go away because he will explode. Return to the room after the explosion and destroy the computer.
8. Now, you have to exit the base but some marines will be on your way. Quickly go back on the first floor and hide in the room. A marines will come. Wait for him and kill him. Exit and kill the one waiting just outside the building. The exit is on the right but there is one more marines walking around. Kill him and exit to clear the mission.
