The Binding of Isaac Rebirth is a remake of the original The Binding of Isaac. It was developed by Nicalis and published on the PlayStation Vita and the PlayStation 4 by Sony. It will be released on November 4th, 2014. It is one of the free games for November for subscribers of PlayStation Plus.
The producer describes The Binding of Isaac: Rebirth as "combining elements of The Legend of Zelda and Smash TV with the roguelike genre." It also "features hundreds of items, weapons and power-ups" and "features over 500 hours of gameplay" in order to unlock every secret in the game. The game is randomly generated, and each run will be different as the enemies, rooms, levels, and drops change throughout each run.
There are over 50 bosses in Rebirth, some returning and some new. An extra layer of complexity has been added to the boss behavior scripts.
When picking up weapon upgrades, it is possible that the various attributes will merge and modify to create a new weapon.
