You've seen this, no? It's the new Kojima Productions logo (above), which was first shown last December and which shows a skull and some sort of helmet. But that's not all, according to Hideo Kojima.
"I can't really say yet," Kojima recently told Famitsu, "but this logo has a secret. It has a full body, a really cool full body. We're planning on putting out a figure version of it."
After again stressing that the logo's body looks "very cool" Kojima joked, "Couldn't someone make like an anime or something with this character?"
For the time being, fan art will have to suffice.
