Has anyone managed a day 1 run ?

[The Real Tetro]

Edit: some of the mad lads in this thread have achieved the run now! Big congrats to Lantantan. Here is a collection of strats and tips we found.

Routes:
Get Basement Key first:
- Foundation + Pool into Pump Room (empty the fountain)
- Foundation + Tomb
- Pool into Pump Room + Boiler Room connection (empty the fountain + lower reservoir by 1 and use boat)
- Workshop for Power Hammer + Pool into Pump Room (empty the fountain), break open the outside entrance to the Basement

Using the Foundation implies taking into account that you will need to lower the elevator, meaning the back side of the Foundation must be made available.

Doesn't require Basement Key:
- Tomb + Pool into Pump Room (lower reservoir by 1 and use boat)
- Workshop for Power Hammer + Tomb

Tomb implies you find dice to reroll the outer room since it can't get offered initially, you'll need garage door and breaker box.
You then need to solve the puzzle in the Tomb to be able to access the Basement and pull the mine cart back.
Dice for rerolling into the Tomb will mainly be found in trunks and only marginally appear otherwise.
From experience, it might be MANDATORY to reroll the outer room TWICE to get the Tomb to spawn, so watch out for that.

Aside from that, you will also need to open the Antechamber, which requires:
- Broken Lever + Greenhouse
- Secret Garden
- Great Hall
- With Power Hammer you can also use Weight Room

Great Hall seems to generally be the best best, but it can have a hefty key cost, especially without a lock pick.
Keep in mind the lever will always be behind one of the corner doors of the Great Hall.

Tips:
Step count remains a big constraint and you need to take it into account. Early Nursery is ideal. Bedrooms are needed regularly to keep the number up. Dining Room is also naturally great.

Finding Laboratory can be very useful depending on the experiment you get, mainly to spawn extra trunks for additional resources, but more importantly more dices.

Office, Study, Drawing Room, Boudoir contain easy extra gems from the safes for which you might want to know the combinations.

Security is not necessary but if you find an access key or if you shut off power from the break box you might want to increase the number of security doors.

Car Keys are pointless since the first time you open the trunk it will contain an upgrade disk.

For Power Hammer strats, batteries seem to mainly be found in the Dark Room (which also can spawn the Broken Lever), the Attic or the Workshop itself. If you already have a Pump Room (or are feeling confident you will find one), you can also pick the Toolshed as an outer room since you won't need the Tomb in that case.

Potential Bug Strat:
It appears that the changes in room rarity that you can get from Wrench and Conservatory are shared among your different profiles at the moment. This means you can engineer your map pool into being highly optimized for this challenge from a different save file.

This does definitely feel unintentional though, so make of it what you will. But know that your fresh files would be affected by the changes you got in your other profiles anyway, even without the intention of doing it for this challenge.

This seems to have been fixed, I confirmed some rooms were their baseline rarity in my latest day 1 attempts. But it was a thing for a while for sure.

Original post:
The chances of that happening seem astronomically low.

With my current understanding, your best shot at opening the antechamber would be to find a Secret Garden Key, which you'd most likely find in the Billiard room by getting very lucky.

The other possibility would be to find a broken lever and the Greenhouse. In both cases, you'd need some major luck for it to happen in the first place AND, depending on which of those you can get, you need to draft your house with the potential side switch to even get to the Antechamber.

You then NEED to get the Foundation, which is not a given as far as I can tell. You will have to keep to mind while drafting that you need to access the backside of it to activate the elevator which could be in different directions.

As I write this, I am not even sure that going down to the Basement from the Foundation is enough, is it possible to reach the Inner Sanctum without having pulled back the mine cart from the other side ?

If so, you'd also need to draft the Pool and then the Pump Room to empty the Fountain, go back all the way there and back.

All that with the initial 50 steps.

You can use the Powered Pump Room to lower the reservoir to 1 step below the top *and* completely empty the fountain, eliminating the need for the Foundation elevator;

the step count really isn't the issue -- my closest run I got all 3 doors of the Antechamber opened and had 40ish steps remaining but couldn't access the north shore of the Reservoir because my Pump Room was unpowered and my Foundation's rear wall was facing a blocked off cell. :((

[The Real Tetro]

Wow, congrats on getting so close to be honest. Relying on connecting the Boiler Room to the Pump Room sounds even more unlikely to me, given how hard it was to do it in the first place in my main save file...

[DrBoop!]

So apparently my first time playing this game I didn't even know how insanely lucky I got, cause I nearly did this knowing nothing about the game. Like what I did basically mirrored what Furious said.

The very first day I managed to open all 3 antechamber doors, got the basement key and just wandered around till it ended because I didn't know what to do with it. I had the foundation, but didn't have a back access so I couldn't go down. I also had the pump room I think? But had no idea that water levels needed to be adjusted. you don't need it to be connected to the boiler room do you? cause all that does is activate the reserve tank right? maybe i've forgotten but i thought you could empty the fountain without the reserve by just putting water everywhere else as well as the 2 main tanks?

Part of it was insane item luck, I had metal detector early so I got a bunch of extra resources, and then I got a shovel and a workshop so I was able to make the even better version and get even more resources, as well as a lockpick kit to save on keys and all the food i needed from dining room and secret garden spreading food

[The Real Tetro]

In hindsight, I don't know if that's "insane luck", even though it was pretty lucky for a first run :D

The thing is "just" opening the three entrances of the Antechamber sounds reasonable on its own, however, it's when you take into account also getting access to the basement to open the door to room 46 that it really changes the way you look at opening the Antechamber itself.

I'd have to check the Pump Room again to be sure, but I don't think you can empty the Fountain and remove one level of water from the Reservoir without the reserve tank that you can only access with the Boiler Room power.

Getting to Antechamber on day 1 is easy, getting to the basement on day 1 is not...

It took me 15 days to get those 2 together lol.
You only need to do it once though, then you can leave well flooded and reservoir at 13 if you want the pool empty...

Wrench can lower rarity on boiler and lab and pump room, so maybe tool-shed start and if you only get 1 it isn't a total waste...
(I did not do this which is why it took so long.)

[Skyggles]

It took me 27 days to finally make it into Room 46. I was just two steps away from loosing, riding back up the foundation elevator. The Dining Room was waiting for me to the north, perfectly aligned as the adjacent room. When I realized it, I could’ve put any football commentator yelling "GOAL!" to shame.

Yeah, but that's not an option on day 1

I mean considering I didn't know how the game worked I felt like opening all entrances was pretty lucky lol. Would have to draw all the correct rooms, 2 of which can only be on the edge, as well as draw the secret garden key, the broken lever, and the great hall and randomly get the correct door. I found in most of my other runs, I got 1 entrance open max.

You theoretically wouldn't have to touch the reservoir with enough steps I believe. As I never really crossed it myself until after I got to 46. You just have to drain the fountain, go down, move the mine cart, then go back and go back down through the foundation.

Another possibility maybe, I'm not sure if the rooms are available on day 1, would be to get the garage and power it, open the outside room and if you're lucky enough to get the uh... I forget the name, the crypt place. If you solve the stuff in there you can also access the mine cart without having to do any water manipulation.

Trying this atm, I find the great hall to be the easiest way to consistently open the antechamber.

It might just be yeah, and coming from the South also might make it easier, but I also found the Great Hall to be one of the rarer rooms honestly. Then again I guess there might be a way to force it to appear with a Secret Passage.

Now it still means you need really good key RNG...

[Lantantan]

It is indeed possible to get the garage, get the breaker room and go outside. I havn't had any luck drawing the crypt yet to move the minecart. Getting first the pool room, then the boiler and the pump feels more painful, but im still trying for it if it comes up.

[FuriousProgrammer]

As far as I'm aware, the Outer Room choices you can get Day One are *always* Root Cellar, Hovel, and Tool Shed; of which Tool Shed is really the only viable option for nearly all runs. The Root Cellar *can* be good if you get the Garage open *extremely* early and already have a shovel, and the Hovel *can* be good if you get an extremely *late* Garage and also have plenty of tools and also are low on gems and also have plenty of steps.

As for the Powered Pump Room: the issue isn't *getting* to the Basement/Reservoir so much as *crossing* it. You need access to the south side to move the minecart and then to the north side **afterwards** to actually solve the puzzle. With an unpowered Pump Room, you have one too many water units to both fully drain the fountain *and* drop the Reservoir by 1 level.

Thinking about it again with the map in front of me, the Pump Room (powered or not) is *required* for the One Day Trophy, as it's the only way to get to the southern part of the Reservoir on Day One! You then have three ways to access the northern part:
1) Power the Pump Room (most efficient in terms of steps, probably)
2) Lower the Foundation Elevator
3) Craft a Power-Sledge (to break down the Cliffside Exit path)

I've never actually done (3) even in my main save, so I'm not entirely certain the Basement puzzle is solvable from that direction in the first place; I don't know if the cart positions reset, either, although I doubt they will.

[AILAD]

Anyone know if door 46 remains open in subsequent runs when you unlock it the first time from the sanctum or does it have to be opened on every run?

[Lantantan]

I can confirm that via two rerolls I got the crypt to spawn, which indeed allowed me to move the minecart. This means pump room is not the only way for this trophy. Alas I failed to open the antechamber, rip.

Offtopic:
To, Ailad, the door does not remain open, but you can prepare a shortcut from outside to that lever room, by locking the minecart halfway and having the gear shifted up and prepped.

[Lantantan]

Aaaand somehow my other main save file got deleted in the process of quiting after the first day?! WHAT. It saved the new game on top of the old one.
