Fan-favourite character Barney Calhoun is back to help Gordon out, going undercover as an officer for Combine. As to be expected, an underground resistance movement formed and Gordon is introduced to them early in the game. A police state was put in place and the citizens suppressed. The world has changed a lot since Gordan's escape from Black Mesa, as now twenty years have passed and a multidimensional corporation, Combine, has taken control of the planet. Continuing the story of scientist-turned-action-hero Gordan Freeman in a alternate Earth world where aliens had arrived from another dimension after a science experiment gone horribly wrong in the first game, players experience a first-person shooter like none other, with outstanding graphics for its time as well as a realistic physics engine, which the game took full advantage of.Īs in the first game, Gordan begins his adventure without any weapons and slowly builds up an arsenal to face consistently more ferocious enemies.

Developed by the Valve Corporation, it was the very first game to use the developer's Source engine. Six years did fans of the critically acclaimed Half Life have to wait for its successor, Half Life 2. Half Life 2 is a first-person shooter by Valve Corporation.
