Usage tips
Word structure
The word is borrowed directly from English and consists of 'multi' (many, multiple) and 'player' (Spieler). So it literally describes a game situation with 'mehreren Spielern' (several players).
EXAMPLE
Das Spiel hat sowohl einen Einzelspieler-Modus als auch einen Multiplayer.
The game has both a single-player mode and multiplayer.
Register: gaming language
'Multiplayer' is a technical term from the world of video games and gaming. Outside this context, the word is practically not used.
EXAMPLE
Er verbringt seine Abende am liebsten mit Freunden im Multiplayer.
He prefers spending his evenings with friends in multiplayer.
Context clue
Whether the game mode or the entire game is meant depends on the sentence structure. If someone says 'den Multiplayer spielt' (plays the multiplayer), the mode is meant. If a game is 'ein Multiplayer' (a multiplayer game), the entire game is being classified.
EXAMPLE
Lass uns heute Abend den Multiplayer von dem neuen Spiel ausprobieren.
Let's try out the multiplayer of the new game tonight.
Typical collocations
When referring to the game mode, the preposition 'in' with the dative is often used. Typical phrases are 'im Multiplayer spielen' (to play in multiplayer), 'im Multiplayer antreten' (to compete in multiplayer), or 'im Multiplayer gewinnen' (to win in multiplayer).
EXAMPLE
Im Multiplayer kannst du gegen Spieler aus der ganzen Welt antreten.
In multiplayer, you can compete against players from all over the world.
