IT'S possibly the best advertisement for Call of Duty yet.

One Japanese fan of the best-selling franchise has been caught on film alert, but not alarmed by the fact the sixth most powerful earthquake recorded was happening right underneath him.

If our translation is correct (and we're not guaranteeing that), his commentary goes something like this:

"Oh my god it's shaking. Is it an earthquake?

"It's massive! It's massive!

"Wait, wait, it's huge. It's massive!

"This is the biggest earthquake ever - really massive.

"Wait ... wait ... it's finishing. It's OK.

"Mum is outside ... everyone has gone outside.

"This must have been big in Tokyo!"

Yet he only stops once - a pause midway through the video where you can hear crashing sounds outside.

Now that's dedication.

The question most commentors are asking? "How good was his connection?"
