Update: In what I think can be safely called an underwhelming reveal, Konami tweeted out a link at 12PM to a page on its website that appears to have a YouTube video on it. When you click to play it, you go through a sequence of explosions on the page–a “Bomberman Roll,” Konami’s timely take on Rickrolling–and end up looking at the image that’s pictured above. Clicking on it takes you to the iOS App Store page for Bomberman Chains, a mobile Bomberman game from 2011 that went free-to-play earlier this week.

Original Story: Konami has published a tease on Twitter for some kind of announcement it’s planning to make this afternoon. We’ll find out exactly what it is in just about an hour, at 12PM PST (3PM EST).

The tweet simply reads, “9/12/14 12:00 PM PST. Boom goes the dynamite.” It’s accompanied by the image you see above, which states, “It’s going to be explosive.”

Beyond that, there’s zero indication as to what this pertains to, be it Metal Gear Solid V: The Phantom Pain or something else entirely. (Perhaps the Metal Gear Collection that was teased earlier this week?) We’ll update this story with whatever it turns out to be.
