Achievements (2024)

Achievements are a mechanic in The Binding of Isaac: Repentance that are obtained via completing specific tasks, such as completing Challenges, obtaining Completion Marks as specific characters, or other miscellaneous things.

The Binding of Isaac: Epiphany includes its own Achievements, from unlocking characters to gaining Completion Marks as specific Tarnished characters. Some content, such as Items, Trinkets, and Characters, are locked behind these achievements, and they must be gained in order to unlock said content.

Completion Marks

Completion Marks are earned by completing specific objectives in The Binding of Isaac: Rebirth. As you complete these objectives, the post-it note on the character select screen fills up with Completion Marks. If objectives are completed in Normal mode, the completion marks are solid black. If objectives are completed in Hard mode, the completion marks are outlined in red. In most circ*mstances, obtaining a Completion Mark rewards the player with an unlock.

Epiphany has 8 completion marks for each Tarnished character in adds, adding up to a total of 48 completion marks added in Epiphany. Obtaining an unlock from a completion mark follows the same rules as the Tainted characters, with a single unlock being grouped up with defeating Isaac,???, Satan, and The Lamb, a single unlock after beating Boss Rush & Hush, separate unlocks for Mega Satan, Ultra Greedier, Mother, and The Beast, and no unlocks being present for Mom's Heart or Ultra Greed. By obtaining all completion marks for a character, another unlock is granted, usually being the character's associated pocket item.
