THE BINDING OF ISAAC REPENTANCE UPDATE
Eternal Edition is a free update to the original game, released by Florian Himsl on May 2015.
THE BINDING OF ISAAC REPENTANCE PLUS
It adds a new category of collectibles called "trinkets," plus new and upgraded items, enemies, bosses, alternate areas, room types, a new character, a new ending and more.

The game relies on a lot of Random Generation to make each playthrough a unique, while additional characters themed after important people from Abrahamic myth can radically change how the game plays. The player visits item rooms to acquire powerful upgrades and faces off against a boss on every floor, heading deeper and deeper downwards with each room cleared. Isaac wanders the maze that is the basement and beyond, collecting items and trinkets to slowly amass enough power to survive a confrontation with Mom and eventually greater foes beyond. Gameplay follows Isaac as he descends into the labyrinth underneath his house. Isaac discovers her intentions and manages to escape into the basement, where, still naked, he goes on the run as he fights off nightmares both physical and mental (using his own tears, no less), discovers memories of his own past, and ultimately confronts Mom in an effort to survive. After his fanatical Christian mother begins hearing the voice of God, she removes all of his worldly possessions and strips him naked, confines him to his bedroom, and unhesitatingly accepts a commission to kill him in sacrifice to prove her devotion. The story follows Isaac, a young boy who finds himself in possibly the worst situation imaginable. The Binding of Isaac is a Horror Comedy, Black Comedy, Roguelike Top-Down Shooter made by Edmund McMillen and Florian Himsl, released in September 2011.
