The Wrath of the Lamb expansion for The Binding of Issac has been updated to version 1.3 today. This update isn’t necessarily huge, but it does add new content and fixes some issues that shipped with the expansion. This update is free for everyone who purchased Wrath of the Lamb.
The new content that is available as part of the update includes a new ending, mini boss, music tracks, items, achievements, a final chapter and golden poop. According to a live stream I watched earlier, the golden poop is filled with coins. Those extra coins can be the difference between life and death in this game.
In addition to new content, a number of fixes have been made as well. They are as follows.
-Ending 12 and challenge 10 now unlock for everyone.
-Brimstone is back in working order
-Alt end boss active
-Familiar conflicts fixed
-item frequency has been fixed
-enemys have been rebalanced
-bosses have been rebalanced
-a “secret boss” now appears where intended
Wrath of the Lamb is still $2.99 from Steam at the time of this writing.
