The Binding of Isaac: Wrath of the Lamb's online multiplayer mode allows up to four players to team up and play through the game's campaign together. The multiplayer mode is similar to the single-player mode, but with a few key differences. Players can work together to defeat enemies, share items and power-ups, and explore the game's vast and unpredictable world.
