The Binding of Isaac drops on Steam today at 10% off making it just $4.49 instead of $4.99, this 10% off promotion will end October 5th 2011. If you’re not sure what The Binding of Isaac is think of it as a really warped original legend of zelda, the one that came in the gold cartridge on the NES except with randomly generated dungeons. I mean just look at this screenshot here, if that doesn’t remind you of when you took something you needed from an old man in a cave, I can’t help you. More than just the randomly generated dungeons Isaac also has 100 unique items, 50+ enemy types, over 20 bosses, 4 full chapters spanning 8 levels, 3+ unlockable classes, multiple endings, tons of unlockable items, enemies, bosses and more. It’s like The Legend of Zelda fell into that toxic waste barrel from The Toxic Avenger, instead of the cartridge melting it became this twisted but bigger and better downloadable game, well after the plastic and PCB melted away that is. Check it out on Steam and we’ve included the creepy gameplay trailer after the jump if none of my rambling makes any sense to you whatsoever.
