Come tutti i giochi multiplayer basati sul motore Source di Valve, Team Fortress 2 usa un sistema client/server. Il client è la copia del programma in esecuzione sul computer del giocatore, mentre il server è il software che connette i giocatori fra loro. Attualmente esistono diverse migliaia di server per TF2 in opera in tutto il mondo.

Un server è responsabile di molti aspetti dell'esperienza di gioco in TF2. Risponde alle azioni dei giocatori aggiornando le loro rispettive posizioni e condizioni, ad esempio quando si sta sparando con un arma, prima di determinare una sua risposta appropriata, ad esempio creando il danno al bersaglio dell'arma sopra citata, e quindi diffondendo i risultati ottenuti a tutti i giocatori, ad esempio mostrando il punteggio dei danni inflitti al bersaglio. Il server amministra inoltre parametri non controllabili dai singoli utenti, quali il tempo dello scenario, il comportamento delle torrette, ecc.

Benefits

Instead of joining an existing server, players can opt to create their own servers to host the game. This can allow the host player to set the map rotation, determining which particular maps and subsequent game modes are played. Additionally, other built in settings can be altered, such as gravity, class slot limit, Highlander limitations and so on. Custom modifications may also be installed on the server to provide alternate gameplay.

Types

There are 2 types of servers that can be run using the Source engine.

Listen/Local server

A Listen Server is a basic server running within a player's TF2 client. It can be easily created through selecting the Create Server button at the main menu. Other players can connect to the server, but the overhead of running a regular client on the same system will often strain the host player's hardware. These types of servers are best suited to LAN-based events.

Dedicated server

Vedi anche: Dedicated server configuration

A Dedicated Server is a standalone server that does not require Steam to run. Dedicated servers are preferred due to decreased overhead, among other factors. Additionally, many dedicated servers are run on high-end hardware in Template:Ws, providing high performance and fast, reliable connections to players, which can seldom be guaranteed on residential connections.

Requirements

While GSPs (Game Server Providers) generally use high-end dedicated hardware to run game servers, anybody can create a server by using a computer running:

Listen server

  • Mac OS X 10.5.8 or 10.6.3 and higher meeting the game's requirements.
  • Windows XP and higher meeting the game's requirements.

Dedicated server

  • Linux (x86 or amd64) running Template:W 2.3.2 or later.
  • FreeBSD (x86 or amd64) running the Linux compatibility code in the kernel and a recent base Linux system from the ports collection.
  • Windows 2000 and later.
