Metal Gear Solid V: The Phantom Pain secrets

This article lists the secrets of Metal Gear Solid V: Ground Zeroes.

Bonus scenes

 * In the aftermath of Missions 3/4/5, 6, 7/8/9/10, and 12, if the player has both a save file on Ground Zeroes, and had managed to extract certain key characters from the Main Mission and Side Ops, the Report screen for recruited soldiers will have a special recruits banner flash and Miller calling in stating that some soldiers they had earlier rescued in Cuba have decided to rejoin them after hearing of them as they had both "survived hell."
 * Some missions have debriefings that are either unlocked completely or otherwise expanded upon by following certain criteria:
 * Mission 7: Either extracting the Red Army brass or otherwise neutralizing them (ie, either extracting or killing them) only after listening to their speech has Miller relaying to Snake the contents of their meeting.
 * Mission 14: Rescuing at least one British POW in addition to the Viscount will have Miller reveal to Snake the Viscount's duplicitous nature and imply that he intends to have the Viscount undergo more severe interrogation for his earlier actions to his comrades before reporting on the delivering of Walker Gears to the various PFs, CFA included.
 * Mission 19: If the player either extracts the Major or otherwise neutralizes him after listening in on his conversation with his subordinate, Miller will relay to Snake what the Major revealed on everything he knew about the events, including that ZRS was planning to kill an old man.
 * Mission 21: If the player decided to extract the CFA executive instead of killing him, Miller will debrief Snake by revealing that the CFA executive wanted to join Diamond Dogs and reveal that it was his higher-up's idea to prolong the fighting with the implication that he didn't necessarily support it.
 * Mission 22: If the player either extracts Mosquito or otherwise leaves some soldiers alive, either he or the personnel will reveal Mosquito's past as a former MSF member.

Easter eggs

 * Shooting the pig's head in Mission 23 will have it oink.
 * Using a cardboard box or performing a quick dive will put out fires.
 * Hiding inside a cardboard box after throwing a stun grenade will have the player avoid the effects of detonation.
 * Using the water gun on radios will short them out without causing the enemy to suspect an intruder nearby, though they will still come to investigate.
 * Shooting the AI pod before and after retrieving it will have it spout lines from MGS3 and Peace Walker, although the latter will require the player to have glass-piercing ammunition to do so.
 * When rescuing Miller, you can actually have Snake say "Kept you waiting, huh?" if you press the action button.
 * Using the water pistol on either Quiet or one of the Skulls will have them briefly quake due to the parasites.
 * Using a water gun on a guard's head during reflex mode will stun him long enough for the player to take him out before he can raise the alarm.
 * Throwing a magazine at the soldier's head in reflex mode will have him be stunned instantly, which works even with helmets.
 * Knocking over low-voltage overhead power lines while it is raining will cause it to discharge electricity in the vicinity, which will also shock and instantly stun any soldier inr ange.
