If the enemy 'find him' during the presentation it "may not be possible to complete" the walkthrough demo, which he describes as "100% more difficult." It's not their booth.
"If you’re going to see the demo at the stage event, I may have to stop because of errors," Kojima-san tweeted. I'm sure no one would eagerly await a total screw up? Nah.
"The demo for the stage event is 100% more difficult," Kojima continued. "The behavior of the enemy is different every time, I can’t help it because I cannot predict it. If I’m found out while playing it may not be possible to complete the presentation as planned." Let's all hope for a 'TGS 2013 difficulty' setting.
"If it was our own booth, extending the time would be possible on a case-by-case basis, but this time it’s not," he said.
The Tokyo Game Show runs September 19-22 with the last two days on the weekend open to the public.
