How co-op works
Two local players share each room as Isaac and a flying co-op baby. Joining transfers a Red Heart container from Isaac; the baby fires using most of his stats but cannot collect items or pickups, so both protect shared health throughout the same run.
About this game
The Binding of Isaac: Rebirth sends players through procedurally generated dungeons filled with bizarre enemies, treasure rooms, and grim secrets. While the core experience is a solo roguelike shooter, local multiplayer lets a second player join in as a floating familiar that fires alongside Isaac. The run structure and permadeath hooks remain intact, making every playthrough unpredictable.

You explore twisted rooms, collect power-ups that radically transform Isaac's abilities, and face off against waves of creatures and bosses. The sheer variety of item combinations keeps runs fresh, and the second player adds extra firepower without changing the fundamental loop. Communication helps when deciding which rooms to tackle or whether to gamble on a devil deal.
Multiplayer is local only, using shared-screen or split-screen depending on how you play. Steam Remote Play Together extends that setup online. Sessions stay tense because death means starting over, and the second player's support can turn a doomed run into a victory lap.

Frequently Asked Questions
How does co-op work in The Binding of Isaac: Rebirth?
A second player joins locally as a floating familiar that fires alongside Isaac. You share the screen and the second player adds extra firepower to help survive the randomly generated dungeons. The core roguelike structure stays the same-same permadeath, same item pickups-but you get the advantage of coordinated attacks and an extra pair of eyes for traps and secrets.
Can I play online co-op with a friend?
Not natively. Multiplayer is local only, either shared-screen or split-screen. However, you can use Steam Remote Play Together to stream the game to a friend online and play that way.
Does the second player get their own character and items?
No. The second player controls a floating familiar that assists Isaac rather than a separate character. They don't collect items independently-Isaac remains the main character who gathers power-ups and transforms throughout the run.
