Lowest number of camera pictures needed to clear Merry Gear Solid with Big Beard ranking?

Question

I've just cleared Merry Gear Solid with the Big Beard ranking - the game is only about 15 minutes long, so it wasn't too hard.

I used the digital camera 6 times and the gun none. I'm wondering if it's possible to complete the game with the Big Beard ranking with less than 6 camera shots (or alternatively, 5 camera shots and 1 gun shot, using the gun on the last guard on the 8th floor)

Answer 1

Turns out it can be done with a total of four camera uses, or three with one gun shot, for the Big Beard ranking.

• First use in the room where you find the gun
• Second use on the 8th floor, to stun the group surrounding the hallways (before the treeline)
• Use the gun (or the camera) on the guard near the stairs after going around the treeline
• Third use on the ninth floor as seen here
