Opferung Isaaks
"The Binding of Isaac" is an indie roguelike video game designed by Edmund McMillen and Florian Himsl, initially released in 2011 for Microsoft Windows; the game was later ported for OS X, and Linux operating systems. The game's title and plot are inspired by the Biblical story of the Binding of Isaac. In the game, Isaac's mother receives a message from God demanding the life of her son as proof of her faith, and Isaac flees into the monster-filled basement of their home where he must fight to survive. Players control Isaac or one of six other unlockable characters through a procedurally generated dungeon in a roguelike manner, fashioned after those of "The Legend of Zelda", defeating monsters in real-time combat while collecting items and power-ups to defeat bosses and eventually Isaac's mother.
