Okay. You win Capcom. I was your staunchest defender. I gave you the supreme benefit of the doubt - that this had to have an ending via a secret unlock method.
I'm now convinced this demo is a marketing teaser demo, that will be updated in the months to come leading up to the game's release. As we get closer to launch, each subsequent trailer will be one new chapter of the teaser. We'll also likely get a new tape with each part.
Honestly, i'm not even disappointed if my assessment turns out to be true. I'm just annoyed that they couldn't just come out & say this. There really is no need for the cloak & dagger secrecy.
What finally had me convinced of this was when I carefully inspected the barricade around the door on the 3rd floor. It's very shoddily, hastily put together. In fact, the quality of this asset is a few shades poorer than almost any other asset in the teaser. It's barely hinged onto the door properly - there are several staples that don't even lay flush with the door asset. Its a reused copy paste asset of the boarded up door on the 1st floor that doesn't fit. We know that that room is featured in a cinematic with family man. We know that the room has proper lighting & geometry. So, its all just a ruse.
This is the company who botched the community management part of SFV's post-launch support. I'm not even surprised that this company is refusing to answer such a simple question, because this isn't unique to just Beginning Hour - having Capcom answer a question about anything, ANYTHING, is like pulling teeth. They are easily the worst when it comes to communicating with their customers.
