Metal Gear Solid 5 Secrets and Easter Eggs Guide
Breakable objects like radio transmitters, antennas, searchlights, toilets and watchtowers will be repaired after you beat five missions.
Characters at Mother Base who belong to the same team or unit will learn different languages.
After saving Miller during Mission 01, he will tell you to say the magic words. Press either Y or Triangle and Big Boss will reply, “Kept you waiting, huh?”
You can beat Mission 04 quite easily so long as you head to the Eastern Communications Outpost beforehand and destroy the communication devices. You instantly finish Mission 04 and receive a secret radio message. Unfortunately there’s no mission score.
Before starting Mission 21, go to the airport and take out the camera posts so they won’t be a pain.
Mission 22 tasks you with incapacitating Mosquito. Turns out, he is the same soldier who helped Miller flee Mother Base in last year’s Ground Zeroes.
While on Mission 23, you will see a pig’s head on a crate in front of Eli’s chair. Blast the pig head and it will “oink!”
Start Mission 28 and go down into the mansion basement. Position Navajo by the candles and they glow. Put Big Boss near the candles and they grow dimmer.
Get the A.I. Pod in Side Op 143 and then blast it with a lethal weapon to hear lines from MGS Peace Walker and MGS 3.
Put on the Raiden or Cyborg Ninja outfits and you’ll be able to dash into enemies to briefly knock them down.
Big Boss sprints at a default 19 miles per hour, but you may increase his speed by researching the following: Bionic Arm Mobility 3 Upgrade (22 mph), Cyborg Ninja outfit (24 mph), Raiden outfit (28 mph).
Quickly recharge the night vision goggles or Rocket Arm sprinting or galloping during the daytime, when the sun is at its brightest.
You can knock down soldiers while beneath the cardboard box! With the box equipped, press A or X to stand and then pull off a quick dive in a soldier’s direction. Caution: he will get back up.
Speaking of the cardboard box, slip beneath one or dash while on fire to put out the flames. Additionally, throw a stun grenade and then hide beneath the box to avoid feeling the grenade’s effects.
Temporarily blind enemy soldiers with the water pistol. You can also throw magazine clips at their heads, which produces a satisfying “ding!”
Is it raining? Shoot down power lines and watch anyone in the area take electricity damage.
While pulling off a CQC combo on someone, press LT or L2 and Big Boss will take his weapon. From this point, you can either knock him out or hold him up.
Disable electronic devices with the water pistol. It’s a great way to mess with soldiers’ heads without alerting them to your presence. You can also blast Quiet with the water pistol and watch her wiggle around.
Head to the ACC after a serious injury to receive a drip bag. Do this two times or more and Big Boss will get a blood transfusion.
Returning to Mother Base? Switch drop off locations while on the chopper and it will change course.
Complete Mission 29 to then extract the skulls Big Boss discovers in the field. You can see them all at the Mother Base Quarantine Platform. Even cooler, finishing Side Op 144 lets you see the Man on Fire. Well, what’s left of him.
Finally, Mission 46 is a big secret and you need to meet certain conditions to unlock it. These remain a mystery, for now.
Beat Side Op 1 and listen to the conversation in Russian. You can only listen to it one time.
