"Unveiling the Game-Changing Programming Trick Behind DOOM's Multiplayer Success"

In an excerpt from his book "DOOM GUY: Life in First Person," id Software co-founder John Romero describes the last-minute development of DOOM's multiplayer mode in 1993. Lead programmer John Carmack implemented a peer-to-peer networking system, allowing multiple players to sync up and play together. The team coined the term "deathmatch" for the competitive mode and introduced the word "frag" to describe kills. Despite a last-minute bug, the game was successfully launched on December 10, 1993, becoming a revolutionary and highly influential title in gaming history.
