Network Play in Quake

Quake includes cooperative and deathmatch multiplayer modes over LAN or the Internet. Additional multi-player modes were later added using "mods".

Quake uses the client-server model, where a server has control of all game events. All players connect to this server in order to participate, with the server telling the clients what is happening in the game. The server may either be a dedicated server or a listen server. Even in the latter situation, Quake still uses the client-server model, as opposed to the peer-to-peer networking used by some other games. Quake thus cannot suffer from de-synchronized network games that could occur from different clients disagreeing with each other, since the server is always the final authority.

Depending on the client's specific route to the server, different clients will get different ping times. The lower a player's latency (ping time) is, the smoother his or her in-game motions are, which makes it easier to aim, move, and score. Someone playing at the PC or within the same LAN as the server gets a substantial advantage due to essentially no lag.

While gamers had been deathmatching each other via IPX LAN connections, serial cable connections, and modems in the Doom, Heretic, and Hexen series of games, it was not until Quake that the Internet deathmatch community really began.
