Psychic Jellyfish LOL

[@jravee5994]

lol you're better off going in one direction until you hit an I AM ERROR room when that shit happens.

[@ariamae-922]

NOOOO GOD NO YOU GAVE ME FLASH BACKS

[@ManOfTheMounten]

creators of the mod should consider making a charecter that starts with the red key. This item is just fun in it's purest form. I honestly can't get enough of it.

[@cobaliumgd9805]

Maybe that would be coins usable item when he beats the witness on hardmode, who knows

[@cobaliumgd9805]

[@Jlittlea1]

They put so much work into this mod

[@SerechII]

[@porsevalex]

Ser ech afterbirth+ took 2 years as well, but ....

[@SerechII]

ThatGuy letsplay and? The small group of modders did a superb job

[@Jonpot]

Cept for their PR... its laughable

[@WrenzyArt]

No it didn't lmao

[@Raikuthedragon]

This item is confirmed in repentance. Its one of edmund's favorite antibirth Intel

[@f_Davide_]

Serious?! I strangely seen nothing about this item in repentance! It would be cool if McMillen (that like a lot this item) would add a red rooms' Easter egg..

[@Alankao06]

Well it’s gonna be fun exploring red room as forgotten

[@SoldierDelta]

@@Alankao06 Adding on to this, I feel like every item in Antibirth will find a home in the Afterbirth DLCs, but Red Key will be ridiculously desired. With Jumper Cables, Car Battery, Battery Baby, Restock... so many items can abuse the existence of Red Key. It won't be as stupid as Damocles with the Lost, but still. Oh, and God forbid if you get Damocles and Red Key. Existance will snap in half and you will breakfast for days.

[@racoononinternet2132]

YES!

[@steampunkastronaut7081]

Can't wait to see it in Greed Mode.

[@KageJason]

there should be a secret red room boss, with it's own ending.

[@thepurified8386]

Found if you use the red key before the witness. But what should it be called?

[@KageJason]

Dylan Carrier something with red in the name

[@zenaidaalejo27]

Kage Jason red blood

[@PillsHere69]

Red baby original the character, donut steel

[@KageJason]

Exodus maybe something that abbreviates into red

[@CJdoesntlikehandles]

red key has to be one of the best items. after all, it lets you get an entire runs worth of items on the first floor

[@miasmi4422]

I would say more like 3 quarters of a run since some people can manage to get a shit load of items in the chest/dark room.

[@ultimaterecoil1136]

Dreptu Mig I think you mean infinite items. Blank card jera rune on chest all you just need is a few batteries to drop from sacks

[@adamxue6096]

We did it boys. This item made it into Repentance. Although it was nerfed to 4 charges, but still really good!

[@uidsea]

Oh that looks fun

[@tsukileo897]

uidsea hi uidsea

[@sufficient4834]

Seeing a single angel room off near the edge makes me wonder if that's where deal rooms are actually located in Isaac

[@neruos8738]

makes sense

[@matthewfanous8468]

its not, but it is a cool thought though

[@user-to2wb5zc7s]

Sufficient if you can go to the planetarium with the red key then it would be op

[@TheEnmineer]

+Ruby Rose You CAN got to the planetarium with the red key, I did it last run. It's incredibly rare, but DOES happen

[@P2xelN2nja]

Sufficient probably was before antibirth

[@user-sl1ei7dn2f]

Red key: expand your basement! (first room for free) (Work in progress)

[@What-Kind-Of-Idiot-Is-This]

Привет

[@Koppu1doragon]

This is easily one of the coolest items I've seen.

[@steampunkastronaut7081]

3:46 That machine knows

[@1God1Fury]

Right now the red rooms are very buggy and on some levels sometimes don't work - entering a red room crash the game. Waiting for Antibirth update where they could fix that

[@omicronalpha8827]

As long as you don't exit and continue you should be fine, that's the only time it really crashed for me

[@Distrance]

+Omicron Alpha Not true. I had an amazing run with Red Key where I found an Arcade in a red room. It had the charge machine in it, so I was using it to explore the floor fully. I seriously went over to a 100 rooms before deciding I was done and happy with my loot .. which was plenty. I left the arcade from a normal door that leads to a normal room and alas .. it crashes for no reason. Upon re-entering the game, the floor started as if I had just entered it meaning that everything I did in the past hour was in vain. And the red key would not work for this floor anymore as I had "exited" the game.

[@zeroaxlkun]

Yeah, sometimes I get random crashes on the game (might be due to other sources ingame) and it really sucks when it happens on a red key run, since it basically kills the entire fun of the floor. It will be amazing when it gets exported to AB+ tho.

[@clawedharmony]

Who’s here after repentance is out?

[@oxob3333]

me

[@nicoRovio]

Yip

[@firefox5133]

i mean technically, everybody is here after repentance

[@bumscrambler3817]

Hey, Syncer. You may not know this but 9-volt and AAA-Battery cause 3 room charge items to become 1 room charge.

[@balbobiggins8012]

That is a Silver key.

[@HowToMolly]

Subscribed. Very helpful content. You should talk with Platinum God website owner to add these there.

[@1ce_s0n1c]

I have an idea of challenge with the red key You start in the room with no doors You can't see where the boss is Red key has charge meter of 1(one room cleared to recharge + You have 48 hour energy for situations when there's a room with no monsters, and the battery drops are increased) And you need to find the boss Also the map is smaller And i agree with Kage Jason that there's needs to be a red room boss(this boss will be final in this challenge) After you beat him you beat the challenge

[@M0mazosMissy]

Red Redemption would be a nice name for that challenge

[@nikitachumachenko3412]

I'd prefer this item not to have charges, but instead just use a key.

[@matthewfanous8468]

like how bethany uses spirit hearts? that would be over powered... due to skeleton key and all that stuff

[@WeaselOnaStick]

it's not that easy to get keys on early floors actually

[@pixelbug2293]

matthew fanous You're talking about a remote situation where you would need to get one very specific item. Its not "too easy".

[@ValsNemesis]

skeleton key is very uncommon

[@Cake_Sauce]

Perhaps whenever the red key does not have a full charge, you can use one key to charge by one. That would make it 3 for 1.

[@mrwholesome2182]

this damn video won't get the fuck out of my recommended list

[@miraakbillcipher660]

RIP

[@KingMako30]

Thank you! I did not previously know the error room condition. This information will be useful when I don't want to accidentally skip a floor.

[@leshiy2043]

Thanks for showing me! Now I can spend more time to get items!

[@latischips1194]

I learned how Red Key works and i also learned what Kenaz does :)

[@europias8626]

Please do videos more often I really wonder to watch them and thank you very much

[@XIIthehangedmanXII]

.... i don't have words for this... JUST GOOD JOB

[@starluigi767]

This item is probably my favorite item in the game.

[@crimsonDestroyer]

so, it lets you visit the Isaac equivalent of the Backrooms

[@Brenchancer]

[@bend7726]

Okay this item is amazing!

[@squishybrick]

This item, the backpack, with the second item being blank card with the fool, and bam, you could infinitely farm ERROR rooms.

[@anaseljaaran2598]

And also add blank rune jera for infinite hp plus nuns habit for infinite charges

[@tanshu295]

When a Single item is better than the whole afterbirth+ dlc

[@SummonerSkipper]

Just because you love antibirth or hate ab+ doesn't mean you need to go down to that level

[@P2xelN2nja]

Skipper well being able to acess devil and angel rooms, multiple shops, multiple I AM ERROR rooms, multiple cursed rooms and multiple bedrooms is kinda OP

[@LewdicideMouse]

AAAAAAGREED

Oh, those stupids

[@NuezWalnut]

2:46 XXXXXXXXXXXXXXXL floor?

[@Dogman_35]

This is legitimately the coolest fucking Antibirth item... Hands down... Which is saying a lot with the INSANELY cool items like ice tears, 120 volt, etc.

[@KendoKetsu]

If you have 9-volt and the AAA Battery then you can just have all of that since it only takes 1 room to charge.

[@karisasani7006]

Until you reach the error room in which case you hope you have a card that teleports you out of the room

[@Brenchancer]

3:48 “fun is infinite” *makes infinite map*

[@UnaturalShadows]

The red key is so cool.. I always knew there were extra secrets behind the walls of the basement

[@hulick6910]

If you use red key too much, you enter the backrooms.

[@QtheAllmighty]

Unbelievably cool item

[@ili9853]

Thats a really cool item.I wonder what sort of chalanges can be made with that.

[@DJBaphomet]

Hmm. "Red Room", sounds familiar... Oh yeah! That one creepy website in the deep web!

[@regis8714]

Damien if only you knew..

[@DJBaphomet]

No. I think he means what the true "Red Room" is. It's a creepy website that shows images of disturbing things. Only on the deep web though.

[@alteredbeast192]

A red room is: Not just a website where people show images of disturbing things, that could make 4chan or bestgore a redroom, they are a website someone sets up to stream acts of torture, rape, murder and other things, which could also act like twitch with a chat.

[@slackerboy8795]

My favorite item

[@hemen1126]

This is a greater idea that the whole afterbirth plus dlc has...AND IT'S FREE! One day, antibirth will be compatible with afterbirth plus...

[@memesta2204]

Wish granted

[@koliaYT]

TBoI : Rependence.

[@justcallmebladealright]

One of the items that was putten alot of work on.

[@zagreus692]

I'am so confused... But it looks very very fun and good! They put so much effort in it

[@matcorona4087]

So wait how does red key work and how do you actually unlock it do you just go as Issac and make it to home? Or straight to witness as Cain e

[@shrimpboom8]

what happens with this+AAA battery+9 volt

[@Syncer]

Up to 128 rooms per floor. You can see near the end of the video where I used red key but no more room was created except error room at the boundary of the floor

[@juridium4510]

Really cool

[@singer.420]

The best video ever :P

[@user-sw4kd5rj1c]

[@CarlosVillanueva-nv5xx]

Schoolbag, voodoo pin + red key + habit + 9 volt= profit

[@ALITERALWHALE13]

So cool

[@PedroHS1401]

now I know how powerful the red key can be

[@cacomeat7385]

This is going to be the best fucking thing in repentance

[@ZombieSlayer876]

No wonder the game always crashes; there's 128 rooms on all floors that you can't even enter without this key.

[@samario7935]

i know this is four months old, but the Red Key actually generates the rooms on the fly rather than 128 being present at all times

[@Kacper42PL]

cool idea for videos :D

[@duyluongle3930]

I think this item just like A Mining game. This item give you extra Angle/Devil/Shop/Treasure/Curse/Secret/Error Room, and will be scattered in random place of that floor. If you lucky enough. You will reach it

[@andrasfogarasi5014]

This strikes me as something a game could be made of.

[@CatandFriends1]

hey syncer, just curious but do you know the seed that you used to find the red key in the beginning?

[@Syncer]

I used one of these: 2ZX3 XKBQ 8EMD 1ASP

[@bladesofnoxus6445]

Syncer how to ublock redkey ?

[@JamesWhite-no2hj]

This reminds me of a few SCPs, specifically the repeating doors and that infinite IKEA.

[@ZyphLegend]

It seems akin to SCP-860. the blue key. They both have the similar concept of opening a door that leads somewhere unexpected

[@jepa_kakanau]

Я так дооткрывался, пока из игры не стало выбрасывать

[@edwardfarrell6340]

[@viovenus992]

I was amazed at the red key opening the Planetarium, this item seems very cool. How is it unlocked?

[@taco3v24]

Jason Shadow you probably already unlocked it, but anyways just kill the witness with Cain, and you unlock it

[@BOONDOX978]

How do you get the red key/ unlock I mean

[@doot2757]
