* While there are plenty of awesome moments in ''Peace Walker'', one of the most memorable is the entirety of the 'Get to the Control Tower' mission, particularly when played in single player. The climax of the mission is when the player encounters their final obstacle; a squad of commandos and a chopper, all of whose sights are centered directly on ''you''. Making it even more intense is that the player is likely running quite short on ammo, and the building the player enters through is promptly blown apart by the chopper, taking away most of the player's cover. If ''that's'' not enough, the main vocal theme of the game, ''Heavens Divide'', begins playing in the background. It is probably one of the most intense and awesome moments of the game, possibly even of the entire ''Metal Gear series'', especially when the player finally takes down the chopper.
** The real kicker is going outside at the start, even though Miller says it's suicide, and getting on the mounted machine gun. ''YOU CAN'T GET HIT USING IT''. Time to go Franchise/{{Rambo}}.
** And to make it even better, the mission ends with things getting tight for Snake, up 'til when the Sandinistas and MSF arrive, gunning down all the enemies in one of the best BigDamnHeroes moments in the whole series. Cue Amanda finally being recognized as "Comandante", and after she hugs Big Boss, everyone starts cheering for him. It's ''such'' a moment of glory.* Big Boss surviving sustained marathons of electric cattle prod shock therapy at the hands of an inept civilian torturer, who is more likely to fry him to death out of jealousy and spite than extract the confession she wants out of him.
** One for the player for surviving all three sessions and arguably breaking Strangelove herself.
* This unforgettable moment happens just a ''leetle'' bit before the hug, it's too awesome for words so let it speak for itself.
-->'''Amanda:''' ''Freeze!''
-->'''Vladamir:''' You ''dare'' point your gun at a comrade?!
-->'''Amanda:''' We will not be pawns of the KGB. We will win ''our own victory!''
-->'''Chico:''' ¡Hasta la Victoria Siempre!
-->'''Guerrilla:''' Amanda! We're home! Look, we're back in Nica! We did it Amand - I mean, '''Comandante!'''
-->'''Soldier:''' Boss, you hurt...?
-->'''Big Boss:''' I'm fine.
-->'''Amanda:''' ''(rushes over to him and utters an exclamation of joy)'' '''Vic Boss!'''
-->'''All of MSF and the FSLN:''' ''(at first whispered, then rising to a frenzy of a crescendo)'' "Vic Boss... Vic Boss. Vic Boss! VIC BOSS! VIC BOSS! VIC BOSS! VIC BOSS! ''VIC BOSS! VIC BOSS! VIC BOSS! VIC BOSS!''
* Taking down Metal Gears is always awesome, but taking down Metal Gear Zeke to Koi no Yokushiryoku, instead of the typical electronic music was pretty damned sweet.
* [[https://www.youtube.com/watch?v=rmGwLyvU35Y&t=19s This cutscene]] reminds us how superior Snake's CQC is when he disarms not one, not three, but ''nine'' enemy soldiers armed with M16's in quick, fluid motion with his bare hands.
* Mixed with CrowningMusicOfAwesome, the background music while you fight Peace Walker is also another one that really pumps you and fills you with determination to win the freaking battle. Though you'd better have some friends to do it, or [[MarathonBoss it'll take a good half-hour to beat]].
** In battles with the Metal Gears of previous games, being stepped on was usually immediately fatal. In Peace Walker, the player can instead trigger a QTE prompt which results in Snake [[CharlesAtlasSuperpower bench pressing]] the mech when it attempts to stomp him and throwing it off balance. In hindsight, Big Boss' DNA does seem quite valuable.
-->'''Kazuhira:''' How can anyone lift a monster like that?
-->'''Paz:''' It is a miracle!
-->'''Paz [[spoiler:[[https://youtu.be/7WnUZfZRfUg?t=4m41s during the final boss fight]]]]:''' Impossible!
* The QTE at the end of Infiltrate the Underground Base. The prompts are so fast it's borderline impossible to avoid losing (and continuing to the next mission), but Big Boss' CQC FoeTossingCharge of eight assault-rifle wielding Peace Sentinel goons (not to mention stealing Strangelove's ID card to escape later upon completion) is totally worth it.
* Meta: Metal Gear Solid Peace Walker is one of the few games that got 10/10 from Japanese gaming magazine ''Famitsu''. And it's a '''PSP''' game.
* Whenever Big Boss gives an awesome speech. Especially the early one which is backed by the strings of the [=MGS3=] main theme. "We gave up our homes. But we're still alive. We're still fighting. And there's ''always'' another reason to keep on living."
* This exchange.
-->'''Big Boss:''' Amanda, join my unit until you've healed up.
-->'''Amanda:''' Your... unit? Who are you? Why are you here?
-->'''Big Boss:''' I'm Snake. '''Serpiente.'''
** The awe Amanda expresses upon learning the man before her is "the great cacique" further establishes how much of a legend Snake has made himself even before adopting his title "Big Boss".
* The sheer epicness that is the [[spoiler:The Boss' AI]], who won't let even ''death'' stop [[spoiler: her carrying out her mission]]. Even after Snake throws absolutely everything he's got, from machine-gunfire to missiles at [[spoiler:Peace Walker]], even after he climbs into [[spoiler:Mammal Pod and starts lobotomizing her piece by piece, she won't go down until she takes ''herself'' down by drowning]]. It's both a marvel and terror to behold.
* Huey gets one for having the guts to stand up to his boss, Hot Coldman.
