Half-Life 2 is a sci-fi shooter video game. It's the sequel to Half-Life (1998). The game was developed by Valve Corporation in 2004. It gathered a number of titles, including 2012 Spike Video Game Award as Game Of The Decade and about 40 "Game of the Year" awards. Many gamers consider it as one of the greatest and most important games of all time.
About 20 years after the events of Half-Life, mysterious G-Man wakes up the protagonist, Gordon Freeman, to inform that the world has been invaded by the Combine empire. City 17 becomes the citadel of the invaders, which take control of the whole planet. At the same time, people and Vortigaunts work together for Lambda Resistance, the underground movement, which believes that Freeman will help them to save the Earth.
Just as the first part, Half-Life 2 is a first-person game, which is divided into several chapters. A player assumes the role of Gordon Freeman and controls him throughout the whole game. He or she starts the way without items and gathers them in the process of game. The game is linear, but some areas can be optional. Like its predecessor, Half-Life 2 has health-and-weapon systems and periodic physics puzzles. Throughout the game, the protagonist faces different kinds of enemies, which can be killed either by his arms or with the help of other materials at hand. In some cases, Freeman can be assisted by the Resistance members. Besides his usual guns, Gordon also gets the Gravity Gun in the course of the game. With its help, he gets an opportunity to draw, push and manipulate various large and heavy objects, which can serve for attacks or defense.
