context: The development of Half-Life 2 began as early as 1999, but in September 2003, Valve's computers were compromised and the game's source code leaked to the Internet. Otherwise, the game was delayed, so a code leak resulted in the game being delayed. [2] Half-Life 2 was released on November 16, 2004. The game proved to be a great success, both in reviews and in sales lists. [3] [4]
