Welcome
Welcome fellow Achievement Junkie... At least that's why I'm going to assume you're here! This guide will attempt to solve any confusion you may have over any Achievements in The Binding of Isaac. Basically, it'll tell you the requirements for each Achievement!
Sure, all of this information is on the unofficial Isaac Wikia, but not everyone knows about that and being quite the contributor over there I thought it'd be worth bringing the guide over here, with a few changes here and there! :)

If you're looking for details regarding a specific achievement, Ctrl+F is your best friend.

May 2015: Eternal Achievements!
This guide has now been updated with the 15 new Eternal Achievements. Please scroll further down or click "Eternal Achievements" in the contents bar on the right.
Help! My Achievements Won't Unlock!
Never fear, for we have a guide just for you. This guide goes over the fixes available for both Windows and Mac users, so if your game isn't giving you your hard-earned achievements this is the place to look!

Wrath of the Lamb DLC
To prevent this guide from getting much longer, I have separated the achievements for the Core game from the achievements added in The Wrath of the Lamb DLC. A similar guide for The Wrath of the Lamb achievements is located here: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=113478016

[quote=snowysquid]no achieves it all regarding to doing any of the challenges?[/quote]

I know this is from June, but for posterity sake:

Each challenge has an achievement tied to it. This seems to be a guide focused on the core game (no DLC) and eternal edition. There's a separate guide for Wrath of the Lamb which includes the challenge achievements (you can find the WotL guide at the very bottom of this guide).

Not sure if you're still active, but I have a question. I don't have the Wrath DLC yet and I've heard that adding the DLC will make the game a little bit more difficult, thus making some achievements more difficult to achieve. What are those achievements exactly, that I have to achieve before getting the DLC. Thank a lot, hope you answer.
