Aliens vs Predator is a first-person shooter developed by Rebellion Developments and published by Sega. In the mission Research Lab for the predator, the player will infiltrate a research lab built around a predator pyramid and look for an ancient artifact: a wrist bracer.

1. Stay on high level and use the Combat Stick to kill the soldiers below you. There are four of them. Then, enter the base and use the platforms to reach the objective.
2. Kill the four marines patrolling the area and destroy the power generator. Now, head to the second level of the building and enter the security control room to take the officer's head. Use it on the panel to enter the monorail station, just outside the security room.
3. Once inside, use your cloaking device and kill the guards one by one using the Combat Stick. Then, go to the left and use the officer's head to gain access to the elevator.
4. It is a trap. When the gaz appears, destroy the panel on the right to stop it and use your cloaking device to hide from the soldiers. Two marines will come. Stay in the elevator and kill them with the spear. Exit and go to the room on the right. Kill the human inside and destroy the computer.
5. Exit the room, kill the guards and enter hallway that will lead you to the next elevator.
6. When up, go to the left, climb up the stairs and head to the objective. Kill the two guards and enter the research lab.
7. Follow the path and protect yourself against the attacks of the xenomorphs. The room you need to enter is on the second floor so look at the platforms above your head and find the one that will lead you to your objective. Once there, take the Wrist Bracer and exit. Stay on the upper level and kill the guards. Then, go to your objective. Enter the room and jump through the broken window to the queen's chamber.
8. Enter the next room where you took the last elevator. A large group of marines is waiting for you. The spear is the best weapon here as you can kill them from a safe distance. Stay hidden with your cloaking device and use the heat vision to spot your enemies. Some of them also use a cloaking device but you can see them a little bit. Stay alert and take your time to kill everyone. Call the elevator and use it when it arrives.
