The Binding of Isaac: Afterbirth+ is a collection of add-ons for The Binding of Isaac: Rebirth (opens in new tab) and Afterbirth (opens in new tab), respectively the definitive edition of the breakout roguelike shooter and a separate DLC pack. Today, Afterbirth+ received its final update, The Forgotten Update, which adds "new items, new unlocks, new trinkets, new enemies, a new character and over 800 new rooms to explore." As creator Edmund McMillen said on Tumblr (opens in new tab), it also comes with a new boss, plus it's free to players who own Afterbirth+.
Earlier this month, McMillen and James Id released the first trailer for their upcoming duo project: The Legend of Bum-bo (opens in new tab), a match-four dungeon-crawler about a distinctly Isaac-y blob named Bum-bo and his favorite gold coin. Back in March, he also revisited Mewgenics, a strange little cat game which McMillen says is back on track but still a few years away (opens in new tab).
