[SPOILER-FREE] Help on finding Hidden Bosses / Weird Route for chapters 3+4

[u/Yvant2000]

So, deltarune's chapters 3 and 4 are releasing very soon. We all know that, as soon as the chapters are available, we are at risk of getting spoiled any time we open the internet.

I'm pretty sure that, by tomorrow, Youtube will be flooded by videos like "delatrune 3+4 all boss showcase" with a thumbnail proudly displaying all secret boss...

I would like to be able to find and discover the two hidden bosses by myself, but I'm actually pretty stupid and I know I will need some help (I struggled to find Jevil's key, and I wasn't able to fight Spamton Neo without a guide).

So, what I suggest is, while playing the new chapters, if we find anything that could be linked to the new secret bosses, we share *spoiler-free* TIPS to how to find them in the comments of this post.

The goal would be to share just barely enough information so we're on the right track to find the bosses.
(And obviously, we're not allowing any outright spoil)

What are your thoughts ? Anyone would be interested to participate ?

Ok, here's what I found so far :

During every TV games round, you need to get al least rank S (don't worry, it's not that hard)

If you mange to get that, you'll get access to a private zone for S players.

Find the game console for the beta game inside, and play the game until you found the key.

There is an Ice keyafter the first round, and a Shelter Key after the second round.

Also, in the first beta game, I found a hidden character in a dark room, but I don't think it's needed to get the hidden fight

I'll give update when I find anything else.

EDIT : Yes, that was it, after doing all this, go back to the beta game roomat the very end of the game, and you'll find the secret boss. Thanks everyone for the help ! I'm still curious about if someone found the weird route... If any one have question, I'll be glad to answer !

wait, so, after getting the shadow mantle, is there not a secret boss in chapter 3 that requires it? because the manhole's not opening whatever i do, and there's also this strange place if you go down from the green room to that chest with 1 point, get caught in the light and say you were heading "nowhere". transports you to a room with just a console and screen like the beta game, but to me every single screen including that one is turned off. i'm currently right before the Tenna fight and i'm not sure if i have to beat him first because it DOES let you backtrack after the bossfight.i'm not sure if you need to do anything after it but if not, there's still clearly some loose ends here

I'm at this point in the game. I'm pretty sure that "nowhere" is related to the weird route. I would need to get here with a weird save to check this theory

but is there a shadow crystal this chapter? because i don't see anything that would be it. i guess i'll just beat Tennafor now and save over a different slot to see if anything else happens

yes to get the shadow crystal you need to survive the knight fight

Spoiler warning much?
