In some ways, The Binding of Isaac: Rebirth is celebrating its 10th anniversary this week, and to mark the occasion, developer Edmund McMillen has announced that the poop-obsessed roguelike's long-awaited online co-op mode will be fully released on December 18. November.
Online co-op for The Binding of Isaac: Rebirth (which is the 2014 remake of McMillen's 2011 original, if you're unfamiliar), was initially announced back in September of last year. Since then, several beta sessions have been held for owners of the Isaac's Repentance expansion.
But now, just over a year since online co-op was confirmed, McMillen has announced that the mode will fully launch for everyone on November 18. It will support 2-4 players online, with its own completion markers, and arrives for free as part of a “sizable” balance update.
But if that's still not enough to get you into the spirit of celebrating The Binding of Isaac: Rebirth's 10th anniversary, the game and all of its expansions are currently discounted on Steam until November 11. There's a 50 percent discount on the base game and a 41 percent discount on the full package, which you'll need to get if you want the DLC.
As for what's next for McMillen, his cat-breeding roguelike adventure Mewgenics (initially announced in 2013) is expected to arrive next year.
