Challenge Name (use heading 3/2)Edit

--NEW LINE-- Challenge requirements (plain text)

Custom Run ChallengesEdit

CompanionsEdit

Pick up only familliars or orbit items. The mulligan, the infestation, and the fish head are acceptable.

Forget Me LaterEdit

You must pick up forget-me-now you find. You must then use it upon finishing the next floor. (An exception is made for Sheol or The Chest)

Blind FaithEdit

Curse of darkness and only angel rooms will spawn no shops or treasure rooms

BookwormEdit

Pick up only books. If you see a library, you have to enter it (unless you have no keys). If you see a book, you must pick it up, even if it's worse than what you have. You also must buy books in the shop if possible. The prayer card and the dead sea scrolls are also acceptable.

No hearts, bubEdit

You cannot pickup anything heart related, so you can't get yum heart, no upgrades, you can't even pick up hearts, nor soul hearts, or the challenge would be done.

Back to BasicsEdit

Do not pick up any item that changes the size or color of the tears your character fires.

Left 4 DeadEdit

Go left unless you can't

Pure skill all the way!Edit

You have to play as the blue baby (??? character) and you are only allowed to pick up soul hearts and bombs.

You are not allowed to use bombs, keys, cards, pills, coins or any other item except for the Poop. This is so god damn hard

I don't want to share! - Multiplayer onlyEdit

Simply put, if player "A" picks up an item, player "B" is not allowed to pick up any related items. When confusion occurs, player "A" decides if the item may be picked up.

To give an example of this is motion player "A" picks up mom's knife the other player cannot pick up any mom related items. Where the item is ambiguous, the rosary for instance, the player picking up the item can decide what category it covers ("Holy" items OR "Items that give soul hearts"). Use of Pills/Tarot Cards is up to the players, Bombs/Keys/Money can be picked up by anyone, and Trinket rules can be decided by players.

The Devil made me do it!Edit

You are allowed to pick up and use bombs, keys, cards, pills, coins and hearts as usual.

You are only allowed to pick up power up/on use items from the devil room.

Exception is the pentagram item. This you are allowed to pick up even outside of the devil room.

I Win These Time Jr. - Multiplayer only bitchEdit

Each person must enter the boss room at the same time. The first person to defeat the boss may pick up the item while the last to finish may not pick up any item inside that boss room. Shop purchases are limited to one (1) per life. The D6 item may only be used on items that spawn from killing a boss or mini-boss and is limited to two uses per floor.

Friendship is Magic run - Multiplayer onlyEdit

This run is a race but it is a race to see who can kill every boss the fastest. Both players must to enter the same boss room at the same time and race to see who can kill the boss the fastest. Now like all good friends you have to share everything. So if player "A" can get in to the item room on a given floor but player "B" cannot then player "A" is not allowed to enter the item room. The same applies for all of the other special rooms. If a player finds the boss room they may not enter until such a time as the other player finds the boss room. Both players must enter the boss room simultaneously. They then race to see who can kill the boss first. If a player dies on any given level the other player (who should be on the same level) must kill themselves so that they can start at the beginning with their best friend!

Exceptions are that you are allowed to pick up coins, keys, bombs, pills and cards independent of the other players ability to do so.

All the rules of the above challenge apply, but the players are also each allowed 1 force pickup. (aka, a player can require that his/her opponent pick up an item, even if they do not want it.) This cannot be done with items found in the devil room or the item shop.

Million Dollar DreamEdit

Play as any character. You must pick up every possible coin you can get (Similar to the We are the one per-CENT challange). However, you cannot spend ANY coins on this challenge even if you reach 99 coins. That means you cannot use the store, gamble, or give to the beggar.

Aperture BoyEdit

Let's practice Science !

GlaDOS is tired of thinking with Portals and want to explore new grounds !

You must pick Isaac.

The rules are the following (the whole items you can pick are listed at the end) :

You are NOT allowed to pick up food : Did you even seen Chell eat something ? Waste of time. Waste of energy. Believe us, you don't need that.

Soul Hearts, Books and Tarot Cards are NOT allowed : you're here to make serious Science, don't pervert your mind in ridiculous superstitions such as magic or religion.

Keys and bombs are allowed (bombs are Science, keys are leading you to Science).

If you pick a Pill, you must eat it immediately if you don't know what it does. Enjoy your Experiment !

If you see a Science-related item, you must pick immediately if it is possible and it doesn't kill you, even if the room is full of monsters and if you must go through a wall of spikes while wasting your last bomb.

Fly pets are allowed for animal research.

You're NOT allowed to shoot poops and blast special rocks : you'll never find Science here.

Don't feed the Beggar, keep your money for research. Which means that the shops are allowed, but if you see a Science-related Item, you must buy it at any price, and pick the very last penny of the very last room if it is necessary. If you can't, you failed at your research and you're not allowed to use shops for the rest of the run.

Pacts with the Devil and Holy items are not allowed.

You are only allowed to pick Science-related items, which are : Blood bag IV, Doctor's Remote, Forget Me Now, The Gamekid, Kamikaze !, Mom's Bottle Of Pills, Mr. Boom, Teleport !, Portable Slot, Remote Detonator, 1 Up, 9 Volt, Battery, Blood Bag, Bobby Bomb, Bomb Bag, Boom !, The Common Cold, The Compass, Distant Admiration, Dr. Fetus, Forever Alone, Growth Hormones, Halo of Flies, Magic Mushroom, Mini Mush, Mom's Contact, Mr Mega, Odd Mushroom(s), The Parasite, PHD, Robo-Baby, Roid Rage, Spelunker Hat, Spider's Bite, Technology, The Virus, X-Ray Vision.

And, if you have Wrath of the Lamb : Bob's Curse, Chemical Peel, Epic Fetus, Icepac, Mutant Spider, The Peeper, Polyphemus, Pyro, Speed Ball, Stem Cells, Technology 2, Cancer, Umbilical Cord.

If you find the challenge too hard, you can allow yourself to get 3 Holy items/Devil items, since GladOS herself needed three add-ons to work well.


Super IsaacEdit

You're a super-hero !

You're allowed to pick-up one pet per run : your epic sidekick ! (Flies are sidekicks)

You're allowed to pick-up one tears modificator per run (Anything changing the shape or effect of the tears, from the Ouija Board to Technology) : your super-power !

The Redemption or Damnation of JudasEdit

You must play as Judas. You may pick up all trinkets, hearts, soul hearts (if damned), eternal hearts (if seeking redpemption), bombs, keys, and money. You may also replace your space item at any time you chose.

You are seeking redemption for your past sins as Judas. You are allowed to pick up any item (except soul hearts) or any item unholy in nature.

You are not allowed to use the Book of Belial. If you do, then you have chosen to fall back to the path of damnation.

Once you decide to fall back to the damnation of your soul, you are no longer allowed to pick up items that increase your health, eternal hearts or holy items.

If you choose to stay holy, then you must go to Sheol to defeat Satan and finish the purification of your soul ( you are not allowed to use the Book of Belial here if you have kept it). If you fell back to the path of wickedness then you are to go to the Cathedrale and blow out the final candle of purity left within your darkened soul forever.

Quick ref:

If redemption is your path

1) All items are avalible to you, but you are not allowed soul hearts or unholy items

2) If you stayed this path your final battle is with Satan and you are not allowed to use Book of Belial if you have kept it.

If damnation is your path

1) All items are avalible to you except, eternal hearts, holy items, or items that increase your health.

2) If you have fallen then you must go to Cathedrale and battle with Issac.

1 - Do not pick it up.

4 - Use the D6 to change the item and you can decide whether to pick up the result.
