Overview
The official expansion to Aliens versus Predator with new campaign, weapons and multiplayer maps. It was released in 2002 for the PC only and developed by Third Law entertainment. It was later bundled with the Gold Edition of AvP2.

Story
The story mode here acts as a prequel to the events of AvP2, and all the events happen at the same planet, LV-1201. The corporates, you as Dunya, are about to find an artifact from "Zeta Site", a mysterious area with an Alien hive and old technology form another alien race. After retrieving the artifact an unpleasant surpirse awaits...

The predator part begins rougly 500 years before AvP2. A group of predators find LV-1201 for the first time and find it is inhabited by aliens. The player must seek and regain the artifact, but an accident with alien egg stasis fields leads him into another time.

The Alien storyline is tied with the predator one in the way that the facehugger in Pod 5 is the player. Bursting from a Predator, it is thereby a Predalien and must feed itself to grow. Eventually, things go wrong and the aliens must escape before the pod is destroyed.

Game Types

The game has various different game types, most of which are in the multiplayer part of the game.

Single Player
-Campaign: the single player is a prequel to many of the events in AvP2.

Multiplayer
-Deathmatch
Free for all. Everyone basically attempts to frag everyone they see. Simple!

-Team Deathmatch
Every race forms a team of their own, which fight against the other two races.

-Hunt
Two teams clash, with one being the hunter and other being the hunted. The prey can become hunters by killing the hunters, thus becoming able to score points.

-Survivor
One player is designated as alien or predator, who in turn attempts to wipe out the survivor team.

-Overrun
Similar to survivor, but this is between two teams and everyone has limited lives. After the time has run out, points are calculated per living team member.

-Evac
One team tries to find the evac point, one tries to kill them. Simple again!

Species - Alien (Fast - Deadly - Strong)

The xenomorphs or also known as the aliens/bugs in Alien vs. Predator are an insect-like creature with armoured skin and lightning fast agility, before you know it... it might be to late, so you need to be wary when dealing with these. The xenomorph will hide in the dark corridors, and will stop at nothing until its prey is dead or captured for hosts. The xenomorph will protect its queen until the bitter end, and you will come across these in the game all of the time. Make sure you use flares or the image intensifier in dark sections - otherwise it will be too late for you.

- Predator (Hunter, Silent, Stealthy)

The yautja, also known as the predator, is a humanoid-type creature. However, they are fast and deadly sporting an endoskeleton structure along with their large muscles and a high intelligence of advanced weaponry. They can often get overconfident at times. You will encounter these hunters throughout the game in certain locations. They are difficult to see when they are cloakced, so keep an eye on your tracker at all times - when the beeping begins be alert, be very alert.

- Colonial Marines (Shoot first - ask questions later!)

The Homosapien, also known as Human, is the race always in the middle of this chaotic war. They have a large collection of weapons, vehicles and ships and always end up on the wrong side of things, but they will stop at nothing and give you one hell of a fight till the end. They are also perfect for 'hosts' for the aliens, who have been known to use human hosts to amass massive colonies. The colonial marines' weapons are not as powerful as the predators', but they will pack a punch and get the job done one way or another.
