In a franchise based world, video games teases are rarely that mysterious. All it takes is one iconic weapon, character or even symbol to confirm that a game is coming in an existing franchise.
If that is the case for this whatever Bandai Namco is teasing here, then I have no idea what it could be. The publisher has made this website teasing ‘something’, and that something has to do with an egg and a microwave. If you click on the site you will come to the picture of a microwave with the word ‘click’ on it. If you comply, a bit of smoke will come out the top and then an egg will roll out (for reference, don’t do this in real life unless you like your microwaves covered in exploded eggs). The only egg-based Bandai Namco properties I can think of are Digimon or Tamagotchi but this seems weirdly abstract for those.
The website is ‘mhaoj.bn’, but nothing obvious leaps from that hint.
I’m not sure what any of this means, but the site says ’10 days’ after the animation, so it seems we have a reveal date. Get comnfy.
