* [[http://www.youtube.com/watch?v=r3fxyw4FH0U "Ambiguity"]] from ''Armored Core 1'' is downright beautiful. It perfectly captures the tragic nature of every ''Armored Core'' world, and the sometimes terrible things that the player does to get ahead in those worlds.
* In the ''Armored Core'' games of old, there was the single player menu music [[http://www.youtube.com/watch?v=x-ykG6lle8w "Shape Memory Alloys"]], as well as the ''[[http://www.youtube.com/watch?v=umAbxRTRyvI AC2]]'' and ''[[http://www.youtube.com/watch?v=iq52vjTFMtM Nexus]]'' remixes.
* [[http://www.youtube.com/watch?v=Bib1ALjlfNE "Apex in the Circle"]] from ''Master of Arena'', and its [[http://www.youtube.com/watch?v=Rst4SvxMt3A remix]] from ''Nexus''.
* [[http://www.youtube.com/watch?v=jCt31W7yUUk "9"]], from ''Master of Arena''. The same music was used in ''Another Age'' and again (with its [[http://www.youtube.com/watch?v=O5zQMjiDrtc remake]]) on ''Nexus''.
* From ''Armored Core 2'', [[http://www.youtube.com/watch?v=czvJtf28-F0 "King Lear".]] Plays during Leos Klein's MotiveRant, and sets the stage beautifully.
* [[http://www.youtube.com/watch?v=E0HRB0yGFCc Artificial Sky IV]] in the end, as well as [[http://www.youtube.com/watch?v=uP-6ymEgH74 "On Satteloid"]] in ''Armored Core 3''.
* [[http://www.youtube.com/watch?v=MeC2JdqgfJw "Blue Braze"]] from ''3'' is real sweet.
* All four [[http://www.youtube.com/watch?v=1EiNKjHHLNc versions]] of "[[http://www.youtube.com/watch?v=c_P14FlamqU Silent]] Line", from the game of the same name.
* [[http://www.youtube.com/watch?v=XJMZQ-pTjpg Artificial Line]] sets an epic tone for your battle with [[spoiler:the IBIS]] in ''Silent Line''.
* [[http://www.youtube.com/watch?v=CqCA1Udh718 "Shining"]] from ''Nexus''.
* [[http://www.youtube.com/watch?v=dTDnRDOO-VA "Red Butterfly"]], another awesome track from ''Nexus''.
* [[http://www.youtube.com/watch?v=2gPhsPaa8HE "Galaxy Heavy Blow"]], which plays during two important boss fights - against [[spoiler:Genobee]] near the end of ''Nexus'', and against [[spoiler:Nine-Ball]] at the end of ''Nine Breaker''.
* The opening theme to ''Formula Front'', [[http://youtu.be/9ryVoHtxxyo "Fake Facer"]].
* Nine-Ball's remix theme from AnotherCenturysEpisode ''R'', [[http://www.youtube.com/watch?v=0FPwjdaOhaw "Nine -novem-"]].
* ''Armored Core 4'':
** The intro and [[http://www.youtube.com/watch?v=J-XQELx4-b8 Overture]], both of which are chillingly good. [[http://www.youtube.com/watch?v=E_YbIwyhT68 "Mr. Adam"]] is also great.
** [[http://www.youtube.com/watch?v=K2Nud4kLLQg "Panther"]], which is perhaps one of the best songs for an opening stage, and comes back again in "Marche Au Supplice", which pits you against four of the best pilots in the game, [[UpToEleven and even without any allies on Hard]], and the song only escalates the battle into a SugarWiki/MomentOfAwesome as you hear the enemies' [[OhCrap disbelief]] if you begin to take them out.
** [[http://www.youtube.com/watch?v=UMNo8z-FVV4 "Rain"]] is beautiful.
** [[http://www.youtube.com/watch?v=FYHv1h7-12E "Thinker"]] is absolutely amazing. To add to this remarkable song, an OverClockedRemix called [[http://www.youtube.com/watch?v=7pDe2bRJLqQ "Goodbye, Thinker"]] takes this action-packed war song and makes it hauntingly beautiful. Both amazing tracks. FreQuency later remixed this track in the form of [[http://www.youtube.com/watch?v=aBXhik9kt7U "Thinker -reprise-"]].
** [[http://www.youtube.com/watch?v=diTUPGCBobA "Fall",]] the final boss theme. An intense, fast-paced fight song with an awesome DesertPunk-ish combination of guitar, drums and [[OminousLatinChanting vocals]]. Then you realize that the lyrics are in English. [[TearJerker Then you realize what they're saying...]]
-->I've already fallen\\
I don't want to fight you\\
It's so hard\\
Wanting you...
** [[http://www.youtube.com/watch?v=moGbUeXMl5E "Fall -Into Grace-"]], an action packed remix of "Fall" from the ''Sunrise'' album.
* ''Armored Core: For Answer'':
** Most of the ''For Answer'' soundtrack, but specifically [[http://www.youtube.com/watch?v=omcG1oJ6i8o "Someone is Always Moving on the Surface"]], [[http://www.youtube.com/watch?v=ofLUejugHUI "Today"]], [[http://www.youtube.com/watch?v=t_7BR0lbIqE "Curtain Fall"]], and the [[http://www.youtube.com/watch?v=7-w-F0HVhTc Outro]].
** Also from ''For Answer'', the [[http://www.youtube.com/watch?v=R2tyuG3Mjm0 "Spirit of Motherwill".]] [[http://www.youtube.com/watch?v=pt_d9YJgyqg It also has a remix]], seeing as how [[spoiler:its wreckage appears in ''Verdict Day'']] and [[spoiler: [[BonusBoss you can fight it again.]]]]
** [[http://www.youtube.com/watch?v=WEsY1Wljl0w "Remember"]] from ''For Answer'', its remix [[http://www.youtube.com/watch?v=zWOxJ5NpIy8 "Remember ~ on your memory",]] and ''another'' remix in ''Verdict Day'' as [[http://www.youtube.com/watch?v=Q_FCYsL9XBE "Mechanized Memories"]] for [[spoiler:the final boss, N-WGIX/v/ White Glint]].
* ''[[VideoGame/ArmoredCoreV Armored Core V]]'':
** [[http://www.youtube.com/watch?v=ozHdnvOxgZc "Vanishing"]] from one of ''Armored Core V''[='=]s trailers.
** [[http://www.youtube.com/watch?v=1gL0lrM03H0 "V for Two"]], the song on the [[http://www.armoredcore.net/acvd/ teaser page]] on the official Japanese website, is a pretty cool piece of music.
** [[http://www.youtube.com/watch?v=l9fnyVD7eL4 "Lament Over the Howling Age"]], which was the Garage theme from the closed beta.
** [[http://www.youtube.com/watch?v=xkP7RpSkKCM "Mecha Dinosaur"]].
** From ''Armored Core V'', we have [[http://www.youtube.com/watch?v=XnvqcSKho5w "Stain",]] the theme of the final boss, [[spoiler:Chief]].
* ''Armored Core: Verdict Day'':
** The song [[http://www.youtube.com/watch?v=q3ipyzisX1Y "Day After Day"]], which plays in the "No future for mercs" trailer. Along with the [[http://www.youtube.com/watch?v=p-EuE1lSF5w live version,]] and its [[http://www.youtube.com/watch?v=ql8KgsC7vjE cover]] which is almost as good as the real thing.
** [[http://www.youtube.com/watch?v=4od42cBGffA "Connected",]] which plays when you first turn on ''Verdict Day'', is awe-inspiring and sets the tone for the entire game.
** [[http://www.youtube.com/watch?v=dVAtqYBUbS0 "Dirty Worker"]], which plays during the first mission, is a perfect blend of ''Armored Core''[='=]s old and current music direction while setting that feel of the next evolution in ''Armored Core''.
** [[http://www.youtube.com/watch?v=MJJ3AzCYooI "The Perfect Rose"]], the track for the workshop, never gets old.
** Each of the three factions has their own theme, all of which make scrolling through the main menu an enjoyable experience; [[http://www.youtube.com/watch?v=-wjNvovMo9k "Venide"]], [[http://www.youtube.com/watch?v=e4zZqkWSQhQ "Sirius Executives"]] and [[http://www.youtube.com/watch?v=2KpKUIC2asI "Evergreen Family"]].
** [[http://www.youtube.com/watch?v=lCDw4aH5yzM "Vendetta"]] manages to make a [[BossRush five-on-one AC battle]] more awesome than it already is.
** [[http://www.youtube.com/watch?v=0Z23y2AC_9E "Forgive an Angel"]] is amazing.
** The theme for when you fight [[spoiler:[[FaceHeelTurn Maggie]]]], aptly named [[spoiler: [[http://www.youtube.com/watch?v=SSR1kOBzPUM "Blue Magnoria".]]]]
** The [[http://www.youtube.com/watch?v=5R56ZXQhPu0 remix of "Stain"]] from ''ACV''.
** "Mecha Dinosaur" from ''ACV'' gets a remix called [[http://www.youtube.com/watch?v=PqOF-4swI84 "Scavengers"]].
** [[http://www.youtube.com/watch?v=2s0JDs6x_g0 "Death Count",]] which is the menu music for [[BrutalBonusLevel Hard]][[SelfImposedChallenge core]] mode. It gets the point across.
** The game got Soundtrack DLC, which means more awesome music. This is mostly remixes of old songs, most notably another remix of [[http://www.youtube.com/watch?v=E5vup40fUl4 "9"]], a [[http://www.youtube.com/watch?v=ecxsCas8UQA "Cosmos"]] remix that replaces the final boss theme (which is also from ''For Answer''), and a remix of [[http://www.youtube.com/watch?v=oYWo84D2-L0 "Dirty Worker"]] which has [[SugarWiki/FunnyMoments Fatman singing the song.]]
