Achievement Guide for The Wrath of the Lamb

Achievements are nice, but sometimes you just want to look up a brief guide as to how to unlock some of them. Here's a brief guide for The Wrath of the Lamb DLC for The Binding of Isaac!

Welcome

Welcome fellow Achievement Junkie... At least that's why I'm going to assume you're here! If you're having trouble with figuring out any achievements within The Wrath of the Lamb DLC for The Binding of Isaac, this guide is here to tell you the requirements for each one!
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! :)

@Chromeno yeah I'm pretty sure I've ran into a bug because the secrets menu says 99/113, but when I view my secrets I have all of them. Weird

[joys and wonders]

@Loc check the in-game secrets menu, there's a chance one of your achievements didn't save

Hey, I got every achivement in the game except for Eternal God, any idea what might be the problem?

[joys and wonders]

@_Lusty_ It should be unlocked by default, specifically above start run should be "Hard mode: off". If it doesn't, check game properties in steam and make sure eternal edition is enabled.

[_Lusty_]

Still no idea how to get to hard mode. I believe I've beaten ??? with all characters and unlocked their respective trinkets but have no idea if I unlocked it or not. Maybe I'm missing a character to do so? I dunno. Any ideas?

[joys and wonders]

@piebye try beating challenge 1

[piebye]

lucky toe wont work does anyone know how to fix ive done it twice

[joys and wonders]

Yes, Platinum God is for obtaining every achievement in both the base game and Wrath of the Lamb.

[Nosepicker1999 (birthday!!)]

kinda confused on the Platinum God achievement. I got Golden God, already, so would Plat God just be for collecting remainder items that are exclusive to Wrath of the Lamb? Also, are there any other tips to get closer to this achievement? Or just keep playing through over and over?

A once clever concept that was ran into the ground years ago.
