ABOUT ALIENS vs PREDATOR™:

Bringing the legendary war between two of science-fiction's most popular characters to FPS fans, AvP delivers three outstanding single player campaigns and provides untold hours of unique 3-way multiplayer gaming.

Experience distinctly new and thrilling first person gameplay as you survive, hunt and prey in the deadly jungles and swamps surrounding the damned colony of Freya's Prospect.

• As the Marine, you'll experience a claustrophobic and terrifying experience where light is your friend, but there's never enough. However, the United States Marine Corps are humanity's last line of defense, and as such they are armed to the teeth with the very latest in high explosive and automatic weaponry.
• As the Predator, you will stalk from the shadows and from above, passing athletically through the treetops to ambush your victims. Although equipped with an array of powerful, exotic weapons and tracking equipment, honor ultimately dictates that you must get in close and take your trophies face to face.
• As the most deadly species in the universe, the Alien offers you the chance to play as the very stuff of nightmares - the monster in the dark swarming forward with countless others, jaws like a steel trap and claws like blades.
• Play all sides off against each other in a series of unique 3-way online modes and go tooth-to-claw-to-pulse rifle in the reinvention of one of multiplayer gaming's defining moments.

AvP uses the Steam Cloud to store game stats and skill information, which is then used for matchmaking purposes.

Title: Half-Life 2:
Genre: Action
Developer: Valve
Publisher: Valve

ABOUT Half-Life 2:

HALF-LIFE sends a shock through the game industry with its combination of pounding action and continuous, immersive storytelling. Valve's debut title wins more than 50 game-of-the-year awards on its way to being named "Best PC Game Ever" by PC Gamer, and launches a franchise with more than eight million retail units sold worldwide.

NOW. By taking the suspense, challenge and visceral charge of the original, and adding startling new realism and responsiveness, Half-Life 2 opens the door to a world where the player's presence affects everything around him, from the physical environment to the behaviors even the emotions of both friends and enemies.

The player again picks up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people he cares about are counting on him.

The intense, real-time gameplay of Half-Life 2 is made possible only by Source®, Valve's new proprietary engine technology. Source provides major enhancements in:
 

• Characters: Advanced facial animation system delivers the most sophisticated in-game characters ever seen. With 40 distinct facial "muscles," human characters convey the full array of human emotion, and respond to the player with fluidity and intelligence.
• Physics: From pebbles to water to 2-ton trucks respond as expected, as they obey the laws of mass, friction, gravity, and buoyancy.
• Graphics: Source's shader-based renderer, like the one used at Pixar to create movies such as Toy Story® and Monster's, Inc.®, creates the most beautiful and realistic environments ever seen in a video game.
• AI: Neither friends nor enemies charge blindly into the fray. They can assess threats, navigate tricky terrain, and fashion weapons from whatever is at hand.
