Answer: What is Half Life 2 mean?

Half-Life 2 is a 2004 first-person shooter game developed and published by Valve. Like the original Half-Life (1998), it combines shooting, puzzles, and storytelling, and adds features such as vehicles and physics-based gameplay. Set roughly twenty years after the first game, players control Gordon Freeman as he joins a resistance movement to liberate the Earth from the control of an alien empire called the Combine.

The game was created using Valve's Source engine, which was developed at the same time. Development lasted five years and cost US$40 million. Valve president Gabe Newell set his team the goal of redefining the FPS genre, focusing on advanced physics systems and non-player characters. Valve announced Half-Life 2 at E3 2003 and released it through its new distribution service Steam after delaying it by over a year. A year before release, a hacker stole an unfinished version and leaked it online.

Half-Life 2 was released on November 16, 2004 and received acclaim for its advanced physics, animation, sound, AI, graphics, and narrative. It won 39 Game of the Year awards, and has been cited as one of the best games of all time. By 2011, it had sold 12 million copies. Valve released a deathmatch mode in 2004. Half-Life 2 was followed by a free extra level, Lost Coast (2005), and the episodic sequels Episode One (2006) and Episode Two (2007). After canceling several further Half-Life projects, Valve released a prequel, Half-Life: Alyx, in 2020.
