Get ready to jump into League of Legends’ PvE game mode, Swarm. Call on a team of friends as you and your friends band together against waves of dangerous enemies and fight to protect Earth from an invasion that threatens all of humanity. But how many players can you play with?

League’s Swarm PvE mode is a highly replayable co-op mode that lets teams dive deep into the Anima Squad storyline while experiencing one of the most unique modes we’ve seen in League in the past decade. Described as a “bullet heaven” type game controlled with WASD, this is one adventure you won’t be able to put down.

If you're looking to join forces in the battle for Earth, here's everything you need to know about the maximum number of players you can have in a game of Swarm.

League’s Swarm game mode has a maximum of four players per lobby. When starting a Swarm game, each player loads a lobby and chooses one of the available champions and the map they would most like to play on.
