A guide to get all achievements in the game, and a google sheet updated with all listed events in the game, including their numbers, names and stat check. (Numbers can change with future updates, so search an event based on it's name.

Given the fact that there are by now 574 events including DLC I had a lot of work to create this sheet and guide, and I also checked some other guides in order to finish it. I created a Special Thanks Section in the google sheet and let a link to their guides at the "Sheet Section" of this guide.

I'd like to also remind that some sheets were not made by me . The Special Thanks Section says exactly which sheets were created by me, and which were only updated by me.

I hope that the guide and the sheet will help you all :)

Each event's choice in this game (except Adivce and Lunch) have a Status Check which will analyze one status of yours and check if it's higher than the other option.



In Event 145 you have to choose between an option that will make hearts with Scott or with Miranda (it's a Pick Love Interest event), but you can actually fail with your choice depending on how your status are low. (Bear in Mind that failing an Love Interest Event will still make you gain hearts with the chosen character).


Here in event 308, you have options which will check your Creative and Bold Status. In most cases, you'll have to choose a higher status in order to succeed. In a case you have both equal, you can choose whatever you want, both of them will fail or succeed.

I honestly didn't understand precisely how the status check works in their values, mostly because sometimes both choices are too low and will fail or vice-versa. Still, I was able to determine that all status higher or equal to 5 at your first event in a playthrough are going to succeed, so keep in mind that failing a event is harder than it sounds.

Ok so here is the link for the Guide of all Endings, Events and Outcomes in the game.

I highly recommend to check this when you're searching secret endings and specific events, since it has a lot more information and explanation of what it's necessary to get them.


As I said many times here, this is not entirely my work and checked a lot of other guides to help me out. So I just leave here all guides that were really useful.

Monster Prom creates a folder in your PC named MPLogs, which contain all of your choices in-game and events you've seen. In case you forget a outcome you've got, you can acess MPLogs in C:\Program Files(x86)\Steam\steamapps\commom\Monster Prom\MPLogs.
Be aware that they only generate and/or are updated after you close the game.
They'll be seperated by days, and will have the following template:

1. Option 1 or 2. (First and Last obviously)
   
2. Success or Failure an event.
   
3. Number of the Event.
   
4. Name of the Event.

"Option2Failure for 0304: WhoToCopy"
That means you've chosen the second/last option on the WhoToCopy event and failed.

All achievements that you can get by playing the game normally, without focusing on any Secrets Endings or specific Outcomes.


"Epic Loser"
"You've been rejected by the first time!"
Pretty self explanatory, fail at asking someone to Prom.



"Casanova"
"Your very first prom date! Let's take a pic of it!"
Succesfully ask a love interest to Prom. You can check exactly which status are required for each character in my sheet, or at that Stat. Requiremente guide.


"The worst!"
"You've been your WORST self. Congratulations?"
Basically, get every outcome wrongly.



"True to yourself"
"You've been true to yourself and always chose the right option. Congratz!"
Similar as above, but you have to get every outcome correctly instead.



"Forever alone"
"You're playing a dating sim, yet you ask no one to prom? Genius."
Ask no one to prom and have all status as low as possible.



"Good on my own"
"You went alone to prom and you had a great time!"
Same as before, but trying get your status as high as you can.



"The best at failing"
"You've been rejected by all 6 main love interests. Maybe dating sims aren't your thing."
Self explanatory, get rejected by all of them. I suggest you visit the shop in every round or focus on a character then pic another one to prom.


"Polyamorous"
"You've gone to prom with all 6 main love interests. What a Casanova!"
Also very explanatory, you'll probably get this while hunting every secret ending in the game.

Achievements that you get buying something at the shop. (Does not involve itens that leads to a secret ending).


"Perv!"
"You bought a used tampon just because. Ugh!"
Buy a Tampom Used by the Former Prom Queen ($1) at the shop (Note that this can lead to a secret ending with Vera only if you choose her route).



"You were naughty!"
"You got the worst Christmas gift"
You can get once per game a gift for free at the shop. Most of the itens you can get leads to a secret endings or improvise a specific status of yours. But there's a chance to coal appears instead, which reduces all your status to 0 and unlocks this achievement. Just keep getting the gift over and over again until it comes.



"Tiger Millionaire"
"You ended a run with 20 MONEY or more."
Self explanatory. I'll give more details at Tiger Billionare



"Tiger Billonaire"
"You ended a run with 99 MONEY or more."
This is actually a lot easier to do than what it sounds. Get the gift at the shop until it comes A Winning Lottery Ticket, it will increase MONEY status to 99 and reduce every other status. Now just be sure to end with that amount, since failing at some events can lead to you losing MONEY.



"Shopaholic"
"You've bought all items at least once."
Note: You don't need to actually buy every single item in the game, just those itens you have unlocked at the shop. Bear in mind that you will unlock more itens as you progress through the game, so it'll be harder to get this achievement.



"Broke"
"You ended a run with a negative amount of MONEY. Get a job!"
While it doesn't need to involve the shop, it is a lot easier with it. Just buy something that gets all of your MONEY to 0, then start to fail at every possible event until you finally lost some MONEY.

All achievements here requires to focus on a specific place or sat with someone every turn until the end of the game. They're all very simple to understand and pretty easy to get.

"Monster Prom the Musical"
"You went to the AUDITORIUM all turns."



"Nerd!"
"You went to CLASS all turns."



"Bookworm"
"You went to the LIBRARY all turns."



"Party 24/7"
"You went to OUTDOORS all turns."



"Dodgeball God"
You went to the GYM all turns."



"Small bladder"
"You went to the BATHROOMS all turns."



"Outcast"
"You always chose the cafeteria table with minor characters."
Lunch time will always have a place with 6 main love int., the shop and those minor characters. Sits with them in every lunch time.

The only thing you need to know here is the Workshop Page of Monster Prom. In case you're new here on Steam, Monster Prom allows players to create content and post them in their Workshop. So that you can get new dialogs and events if the game starts getting predictable.

There's nothing I can really add on this section. The Modtool in this game isn't hard to understand, and you can create and post something really half-baked and erase immeaditely after getting those achievements.


"Mod-tacular!"
"Subscribe to and play a Steam Workshop mod."



"Mod-alicious!"
"Create your own custom character in the Modtool!"



"Mod-tastic"
"Publish a Steam Workshop mod for the first time!"

Some achievements are unlocked after you get a specific secret ending, but you'll get an achievement for getting every single ending in the game. Again, you can check every event's status check and how to get those endings (buying item or randomly) in my sheet.

If it doesn't seen to have a specific item at the shop, keep unlocking secret endings with all 6 main love characters.

Even though most endings you go to prom with someone else in the game, keep in mind that characters' secret endings don't required any stats to ask them to. You only need to have a succesful outcome in all events of an ending.


"That was unexpected"
"You unveiled the first secret ending."
A secret ending can randomly appear at someone's route or buying an item with a "event" flag on it.



"Boo!"
"You fooled everyone and become the coolest ghost in town."
Buy A Blanket With Two Holes ($5) at the shop to get this ending.




"Love from the depths"
"You released an ancient deity just to date her. Sweet!"
Buy The Power Totem of Z'Gord, Ruler of the Dark Realms ($10) at the shop to get this ending.



"01101001 00100000 00111100 00110011 00100000 01110101"
"You saved Calculester and wen to prom with him. Robolove!"
Buy An Arcane Floppy Disk ($8) at the shop to get this ending. Bear in mind that the initial event will occur only when you visit the Library with that Floppy Disk.



"I wanna buy... your heart"
"You dated the game's shopkeeper. What a plot twist!"
Visit the shop without buying anything three times (Have to be unlocked first, keep getting secret endings).



"Wowie!"
"You took the cutest orange blob ever to prom."
Buy A Set of Weirdly Specific Greeting Cards ($12) at the shop.




"Enter The Coven"
"You saved the world and brought Joy to Monster Prom. Sweet!"
Buy The Blood of an Angel ($12) at the shop.




"Prank Masterz!"
"You played the ultimate prank! LOL!"
Buy Ancient Tome Of The Forbidden Arts ($7) at the shop.




"Cagatió"
"You unveiled the secrets of the greatest Catalan traditions."
Obtain The Caganer from the gift at the shop.




"The Funeral"
"You got one of your classmates... murdered? Congratulations?"
Obtain The Mind Control Classes from the gift at the shop. Bear in mind that this item leads to 2 different endings. You need to fail in 2 or more events to get this achievement.



"Orgy manager"
"Who needs prom when you can have an orgy? Good job, champ!"
This ending will unlock only after you complete at least one secret ending with all 6 main love interests. It'll appear at Polly's or Liam's route.



"Christmas Dinner"
"You got the best Christmas gift: love."
Obtain A Date With Valerie from the gift at the shop. It will unlock after you complete every ending with a purchase from the shop, including gift endings. This will probably be one of the last endings that you will unlock in the base game.



It's basically the exact same thing about achievements in the base game. I highly recommend to get all secret endings which don't involve the DLC, but feel free to do in any order you desire.


"Great commander"
"You aided in the failed attempt to conquer the 8th Circle of Hell."
Buy A Map ($8) at the shop.



"Hey, listen!"
"You helped to bring peace to a fighter's heart."
Buy A Fairy in a Bottle ($10) at the shop.



"The one with the evil twin"
"You faced the evil version of a Coven member."
Buy A Free Lore Coupon ($7). In an event with The Coven and Dmitri, choose Faith's Route (SMART).



"The one with the big reveal"
"You revealed one of the Coven's biggest secrets ever."
Buy A Free Lore Coupon again, but choose Hope's Route instead (BOLD).



"Ultimate Trip"
"You went on the weirdest trip ever"
Buy Very Weird Drugs ($10) at the shop. It's only available when there are exactly 3 events left.



"Well done, player"
"You broke the 4th wall... just for love."
This is the last ending that you can possibly get. Complete every other endings and get all ending and polaroid photos first in order to unlock this. You have to sit at the Narrator's Table during Lunch. It'll be in a place off-scream to the left, accessed only by your arrow keys.

There are two DLC achievements that will be unlocked by getting a specific outcome in the game. Knowing that does make getting them a lot easier, but be aware that failing an event requires to have the other status check higher and/or have this status low.


"Ultimate Lore"
"You REALLY enjoy learning new lore, huh?"
You get this achievement by having a succesful outcome with option 2 in the second event of Hope's Secret Ending.
(EVENT: 864/ Hope2) Option1: CREATIVE/Option2: BOLD.



"Raise your hands up"
"Well... that was unexpected."
You get this achievement by having a fail outcome with option 1 in the second event of Fourth Wall Secret Ending.
(EVENT: 849/ FourthWall2) Option1: CREATIVE/ Option2: SMART.

Ok here is the worst section. Basically all achievements here are to unlock and see every single thing in the game (outcome). This is very time consuming, we already know that. However, you can cut a drastic time if you organize yourself.


"Ending explorer"
"You've already unveiled half the secret endings. Way to go!"



"Ending connoisseur"
"Whoa, you've seen ALL THE SECRET ENDINGS."
(For the Base Game).


"Ending Flood"
"All of the First Term endings weren’t enough, so you went for the Second Term ones too. Fierce."
(Including DLC).

Ok first things first. Getting every secret ending is not something hard, but can be very frustating since some of them are completely random. Just play a long game and keep focus in one character at a time. As for the "gift" endings you can actually restart the game over and over again until it finally comes. (Bear in mind that even though you're reseting, it will counts any event and outcome taken).


"Whoa, you really like this game!"
"You've seen half of the events in the game. Get some rest."



"Go play outside!"
"You've seen ALL THE EVENTS in the game! Just wow."
(For the Base Game).


"Event Storm"
"You can't get enough of your favorite monsters, can you?"
(Including DLC).

All events are listed in my sheet and separately by their types. They are LUNCH/SECRET ENDING/SINGLE CHAR./TWO CHAR./MULTIPLE CHAR./ADVICE/WEEKEND
With ADVICE and WEEKEND events happening with 2 and 3 players, respectly (You can get them playing with yourself too :P). All events in the sheet have their Names, Locations and Numbers (Be aware that numbers can change in future updates, since they already had once).


"Honey... this isn't healthy"
"Okay, you've seen all the outcomes in the game. We didn't think we'd see this day!"
(For the Base Game)


"Outcome Tsunami"
"Reading ALL OF THIS is basically like reading +1,000 pages of a book. Put it on your resumé."
(Including DLC)

The Outcome achievement is the real monster here. There is no easy way honestly, you unfortunately have to get every single one of them by replaying the game over and over. You can reduce it's time by getting one different outcome and go back to menu (that will finish the game, but it WILL COUNT as one Outcome showed in MPLogs, so you don't have to play an entire game just to count 1 or 2 new outcomes) although it still will take a very long time to do it.

Here's some friendly advice: Don't hesitate if you have a chance to fail in a event which has a Smart Check. Smart Status is pretty high in the beginning of the game even if you don't focus on it, and succedding an event will sometimes increase your Smarts Status. So if your Smart Status is low, I highly recommend you to take advantage from it.

EDIT: For some unexplicable reason I've unlocked the DLC's OUTCOME achievement after only seeing all EVENTS in the game. I've got both "Event Storm" and "Outcome Tsuanmi" TOGETHER, even though I didn't see every outcome in the game! This must be some kind of glitch that is present when you unlock the Event Storm Achievement.
