Secrets and facts

[Anbo1]

I consider my self very god at BOI. Yes, I have no steam achievments for it but thats only because if you play BOI on a Mac, the steam achievments won't work until you play on a windows computer at least once. Im goint to fix this issue for myself soon, but that is unrelated lol.

I know a lot of the secrets, items, hot the items work, what they do, trinkets and what they do, cards and pills and what they will do, (or probably do) rooms, how the rooms work, whats probably going to happen in the room, where is the room going to be, etc.

But I just read and article on BOI about the the story line (http://steamcommunity.com/app/113200) and it was a MASSIVE eye opener! I can't really explain it to you because... Im not so sure how to explain it to you.

*shakes head* Here is a list of secrets, easter eggs, hints, tips, glitches and basically notes-to-put-into-consideration that you might not of heard of for the next time you play Binding of Isaac.


If you use a pill and it has a negative effect (e.g. health down) it will be turned into a positive pill if you pick up a PHD or Lucky Foot; but usually tend to be the opposite of the original pill (health down = health up). Also if you are on 1 heart or less (only half a soul-heart if playing as ???) and you have a "Bad Trip!" pill, notice it turns into a "Full Health" pill? Also "Telepills" aren't that useless. They can teleport you in to the secret room, super-secret room, shop, treasure room, and (if you are really lucky) the IAM ERROR room! (Only if you are lucky.)

Here is my personal favourite secret: To play as GUPPY (I KNOW) you need to have at least 3 of the following 4: Guppy's tail, guppy's head, guppy's paw, the dead cat. Once you do that, You unlock "Guppy's hairball" (which is a familiar that follows you, but is a little erratic. If enemies touch it, it basically absorbs it and the hairball gets bigger) As well as unlocking the hair-ball, you also get to play as GUPPY for the rest of the game. Sorry, he isn't a permanent unlock in the character screen :( He changes form into the black and white cat, gains the ability of flight and an improved version of the mulligan (spawns blue flies)


The game doesn't end when you beat Mom. Nonononononononononononono... The game ends once you kill Satan, Isaac, ??? and Mom about one-hundred-thousand times each. When playing, make unlocking the characters a priority (with the exception of Judas and ??? as those guys you get by not dying, basically) because as soon as you unlock them, the better.

Please let me know some fun-facts, secrets, easter eggs, tips, etc. that maybe that ONE PERSON doesn't know, or only one person knows. Also things that I might have missed. Thanks! (Btw most of the stuff I mentioned; to do most of it you need the Wrath of the Lamb DLC)

[Yes]

trolling?

Must be, wasn't all of this common knowledge?

Well, not everyone knows about guppy =D

Some people play 200,000 times and get guppy once, where others get guppy twice in a row

I dunno, a lot of things that I might not know or others might not know

Well, getting Guppy isn't that hard. I've never tried, but today I just felt like it, and to my surprise, done it on a single playthrough without effort.

First I got Guppy's Paw, then some level or two later, found a Satan Room with both Guppy's Head and Tail. I had enough hearts and soul hearts to get them, so I just did it, but Head replaced Paw on the Item slot, so I thought it was useless. When I walked out of the room, Cain transformed into Guppy, which I've never seen or used before, and it got very powerful. It got me all the way to The Chest, and I defeated ??? without a worry. Also, I got the Mama's Boy achievement without even trying. Three achievements on a single playthrough, all out of pure luck.

Of course the achievement system for this game is bugged and I had to restart Steam in order for it to recognise them, but... well, at least it did.

Note that when you beat The Chest with Cain, you'll get ???'s achievement, because this set of achievements is all messed up. Here on the wiki you can see for yourselves: http://bindingofisaac.wikia.com/wiki/Achievements

All of this just reinforces the fact that this game is not just about skill but about the luck you have finding useful items.

Last statement not true...
You can literally finish the game with almost any setup you come across.

True story.

But after reading the article it was a massive eye opener, as I didn't think of the game in a dark, sinister way. That secret message; had no idea it existed. Im trying to find out if I have missed anything.
