LAN multiplayer has been a staple of PC gaming since the early 1990s, providing a convenient and low-latency way for players to compete against each other in the same physical location. This type of multiplayer experience was particularly popular in the Call of Duty series, with games like Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2 featuring robust LAN support. The inclusion of LAN multiplayer in these games allowed players to gather with friends, engage in competitive matches, and experience the thrill of multiplayer gaming without the need for an internet connection.
