* BrokenBase - The release of ''Evolved'' divided the fanbase into two camps. On one hand, some people claim it to be an enjoyable action title, even if it isn't on the same level as its predecessors. On the other, some call it a disgrace to the franchise and that another strategy title should have been made instead. Over in Japan, the reception is simple and universal - while fans have no problems with another genre spin-off (as they have access to ''Gun Hazard'', ''Alternative'', and ''Online'' unlike the rest of the world), they point out its numerous design flaws and don't see it as a successor to ''Gun Hazard'', let alone the brilliant ''Online''.
* ClicheStorm - ''Evolved'' rather ironically degenerates into this.
* CompleteMonster: Driscoll in ''1st'', even when playing the USN scenario who manages to make some of the officers in the USN likeable enough he keeps being a complete dick who treats Kevin like trash and his soldiers like tools.This would put him right on Jerkass territory but then there's the stuff he does to [[spoiler: Maria]] and [[spoiler: Karen]] along with all the scheme with the Sakata Industries.
** Serov in ''3''. He destroyed a city and killed several people just for the sake of researching his experimental Wanzer Genie Arm. He's also so insane, he would attack his own allies randomly.
* ContinuityLockOut - Every canon video game entry are continuations of unresolved stories from the previous one chronologically. This is because the franchise tells its story like a TV serial: the standalone stories (for newcomers) often interconnect with other ones and tie back to a larger overarching storyline (for fans). ''Front Mission 2089'' leads into ''2089-II'', ''2089-II'' leads into ''1st'', ''1st'' leads into ''4'' and ''2'', ''2'' leads into ''3'', and so on for an 80-20 split between the standalone and on-going stories. Most evident in ''5'', which is a 50-50 split, but really requires having played ''all'' of the previous titles to truly understand. Also very evident in the [[LoadsAndLoadsOfCharacters 70+ characters]] that show up in at least two or more of the games, some showing up as many as ''five'' times [[spoiler:(Royd Clive from ''1st'', Morgan Bernard and Glen Duval from ''5'', etc.).]] Oh, and add in the other ''Front Mission'' media which only adds to this, and it becomes quite obvious that this is one of those things you REALLY have to get into, or don't even bother trying! This does not apply to ''Gun Hazard'' (which takes place in a completely different universe) and ''Evolved'' (which is a reboot story-wise).
* CrowningMusicOfAwesome: In contrast to ''4'', which had a Forgettable soundtrack, ''5'' has much improved music. Standouts include the main theme Scars of the War, the Strike Wyverns theme, and Deliverance, the battle BGM for the final mission.
* EnsembleDarkhorse - Darril Traubel from ''4''. Besides his game proper, he shows up as a playable character in ''1st'' and ''5'' (and is recruitable later in ''5''), and is one of the best pilots in ''5''; strategy guides rate Darril as being more useful than a counterpart S-Type device pilot. May have something to do with the fact that he's not as goody-two-shoes as other protagonists in the series.
* GameBreaker - A few of these in the games.
** Melee users in ''1st'' can learn Melee Skills like First (gives you a chance to strike first, even if your opponent is using Short weapons), Stun (chance to keep an opponent from being able to do ''anything''), and Double (allows you to strike again with your other arm). Anyone with all three skills can wreck major havoc on the battlefield.
** Short-range users in ''1st'' are equally as broken as they can learn Duel (lets you choose which part to attack directly), Speed (adds an extra bullet attack when using multi-hit weapons), and Switch (see Double). Anyone with all three skills can outright demolish an enemy unit, even boss units, from full health to absolutely nothing!
** This passes through into ''3'' as well, where incredibly skilled or lucky wanzer pilots could let off two to as many as six attacks through Skill Chains. There's NoKillLikeOverKill.
*** And that's not even counting the Hoshun Mk. 112, which packs not only the instant-death skill "Body Smash", but also a particle cannon whose damage type can't be defended against and whose ridiculous AP cost can be mitigated by using one of two "double attack" abilities to have it follow up a cheaper lead-in.
** Overlapping with Gundamjack and FailsafeFailure, in '3'' if the player can successfully force an enemy to eject (or just gets really lucky), the player can have a pilot hop out of their wanzer and into the enemy's vehicle. The computer player doesn't know how to get into any vehicle that a player has ever piloted, resulting in them being reduced to shooting your death machines with their pistols. The player doesn't even need to stay in the new vehicle; he can switch back to his wanzer if he prefers and there's nothing the computer can do about it. If that wasn't enough, you get to keep wanzers you "capture" this way.
*** Actually, it is possible for the computer to steal your wanzer when doing this. It's just so infrequent and rare you have to be very, very unlucky to have it happen.
** The Smash abilities in ''3'' in general. You can activate them with melee, sniper, or missile shots. They '''WILL''' hit the enemy regardless of accuracy. A body smash is a straight up instant kill. An arm smash will ''ALWAYS'' destroy the left arm first (and the game never equips weapons on the right arm, only shields), which means you screw over your opponent from doing any significant damage to you afterward, since all they can do is punch you with a Hard Blow.
* GeniusBonus - Remember Paul in ''1st''? The hippie, with the mech named "Rainbow"? Yes, you snorted and laughed at a weapon of war being named after pretty colors. Because you're not too familiar with Literature/TheBible. When the Flood is over, God sets his bow in the sky as a promise never to point it at humankind again. That's right. The rainbow is God's own personal planet-killing WaveMotionGun.
** I thought it was a reference to Gravity's Rainbow, the parabola a rocket makes just before it blows your torso out, from Pynchon.
* ItsEasySoItSucks - Another complaint about ''Evolved'' is how easy it seems sometimes, with player wanzers being able to regenerate damage in any difficulty, power-ups that heal damage, replenish ammo, or restore energy respawning everywhere, and complaints of non-existent AI, except for the bosses.
* MemeticMutation - YTMND latching on to the "Secret Nazi Forest" made of [[NoSwastikas paths on the Cenktrich map]] in ''Gun Hazard''.
* MoralEventHorizon - Driscoll crosses this when he reveals [[spoiler:what he did to Karen]] in ''1st''.
* MostAnnoyingSound - The limited and frequently repeated taunts spouted by ''Evolved's'' boss enemies get old ''fast.'' And many boss enemies will repeat a line ''every time'' they use a particular attack.
* MostWonderfulSound - in ''3'' onwards, the skill activation sound... especially when it's in a chain.
* NeedsMoreLove - ''FrontMission'' in general, and ''4'' in particular.
* TheScrappy - Molly O'Donnell in ''1st''. Molly rarely does anything in the OCU scenario and when she does, her actions don't really benefit anyone. Rather, the rest of the Canyon Crows get pissed off at her [[spoiler: for trying to lure them into a USN ambush shortly after she's recruited.]]
* TheyChangedItNowItSucks - ''Evolved'' gets this a lot. Most people who dislike ''Evolved'' cite the genre shift as a reason, saying that Front Mission is supposed to be about turn-based strategy. Though this only applies to everyone outside of Japan, considering ''Evolved'' is not the first spin-off (''Gun Hazard'', ''Alternative'', ''Online'') and is definitely not the first TPS spin-off (''Online''). And none of the spin-offs were released overseas. For Japanese fans, it comes down to one reason - it throws out almost everything that makes Front Mission "Front Mission". Sure, the customization is there and it's fun to blow things up in a wanzer. Unfortunately, that's about it. As for why it's not like really "Front Mission"...
** In the story campaign, there's no multiplayer co-op (''Gun Hazard'' does), there are power-ups found everywhere or dropped by enemies(''Gun Hazard'' does this more realistically, like ammo crates in a supply depot and never dropped by enemies), ally units can't be killed (''Gun Hazard'' does), and there's no real depth to the combat (''Gun Hazard'' does). Online multiplayer is heavily unbalanced in many ways, like in the progression system - experienced players have access to top-tier parts that flat-out overpower gear that newbies start with. Throw in how overpowered some weapons are, like Bazookas, and ''Evolved'' is a far cry from the well-balanced ''Online''.
** As far as the story of ''Evolved'' goes, it's a complete disgrace. Aside from outsourcing the game development, art design, and music, Square Enix also "outsourced" the storytelling to Motomu Toriyama. Yes, Motomu Toriyama. Instead of an intricate, mature tale about mankind versus itself, ''Evolved'' ironically degenerated into a ClicheStorm as it rehashed every major mecha cliche in existence. As Front Mission was penned by a team of some of Japan's best writers (most being scriptwriters or novelists), it's tragic to see a product with those words churn out something incredibly bad.
* ViewerGenderConfusion - Emil in ''Gun Hazard'' is a good example of this....
