Let's end on something ridiculous, something that's more 'Kojima' than that 20 minute ladder-climb in Snake Eater, and something that'll bring about every shocking reaction under the sun. What's that referring to? Well, I'll keep spoilers out of it, but there's an easter egg doing the rounds for Phantom Pain that people are slowly discovering and plastering around the web - we've included it over here. To trigger it, look to your Side-Op mission list around Chapter 6 onwards. You should see one named something like "Rescue the survivors of Mother Base". Go to the area - preferably with D-Dog as he'll help locate them - and complete the mission. Then, go to your ongoing Mother Base and drive to the Med-Bay strut. Head to the second floor and inside the door with the blue light, where the formerly under construction sign will be replaced with a door you can access. Head inside, and have your mind blown, reassembled and blown all over again. Let's just say if you thought the intro to the game was absolutely ridiculous, Kojima's got your number, and he knows exactly how to punch it. Are there any I missed? Let everyone know your own tips, tricks and little-known secrets in the comments below!
