Half-Life 2: Episode Two is the second in a trilogy of new games created by Valve that extends the award-winning and best-selling Half-Life adventure.

As Dr. Gordon Freeman, you were last seen exiting City 17 with Alyx Vance as the Citadel erupted amidst a storm of unknown proportions. In Episode Two, you must battle and race against Combine forces as you traverse the White Forest to deliver a crucial information packet stolen from the Citadel to an enclave of fellow resistance scientists.

Episode Two extends the award-winning Half-Life gameplay with unique weapons, vehicles, and newly-spawned creatures.
