* BreatherLevel: The last storyline dungeon is significantly easier than the work getting into it.
* ClicheStorm: It'd be easier to list the number of Gundam and JRPG tropes this game ''doesn't'' invoke. The basic premise of the game: a young boy and his childhood friend witness [[DoomedHometown the destruction of the orphanage where they lived]] by a black Mobile Suit and swears revenge, they meet a [[EasyAmnesia amnesiac]] MysticalWaif and joins LaResistance to fight a shady organization that seeks to destroy the world, all while wearing the most nonsensical of outfits, and [[spoiler:a mid-story twist that presents an even bigger threat for the characters to take down.]] Anybody well-acquainted with the various tropes employed by Gundam as a franchise will see every inch of the plot coming a mile away, [[spoiler: ESPECIALLY the Hal/Vladi and Tremmie sibling plot]]
* DemonicSpiders:
** Any enemy that's able to inflict the short status due to how dangerous it is. Under the short status, the character isn't able to do anything, while the heat status merely prevents the player from using regular and boost attacks. Any teammate infected by short is basically a sitting duck until it's removed or it goes away after three turns.
** The Kamikaze Raven. Randomly encountered mid-game, it just has a single hit point, but a insanely high speed and melee damage and in later stages, the player will encounter more than one. The result is that it always moves first, has an insane crit rate and hits hard enough even without a critical hit to instakill whoever it targets, even if you defend against their attacks. Hope to hell that the player isn't ambushed by two of them or else two party members will end up dead and a possibility of a game over. The only way to counter it is to use an always-moves-first boost or Counter Snipe, otherwise a TotalPartyKill will ensue in three turns.
** On a related note, if the player travels out east from Eisengrad, they might encounter a Hammer Gouf, which not only has a lot of hit points, but he can kill any mobile suit with ease, resulting in a GameOver real fast. Even if the player travels east much later they have better mobile suits and at a higher level, they're still very dangerous.
* DifficultySpike: A very noticeable one. Starting after [[spoiler:Hal's betrayal and TheReveal that he's Vladi Zarth]], the bosses become ''much'' harder, to the point that they can OneHitKO (or at least come ''very'' close) even your strongest Mobile Suit with their Boost attacks if you don't either defend or put up the proper counter. Even then, it can be a bit of a guessing game as to which counter you should put up, as most of them tend to alternate (albeit with a preset pattern) between beam, bullet/shell and melee attacks.
* GoddamnedBats: Any mobile suit that has a short-circuit inducing attack, it stun you and unlike overheat, you can't even switch member or cast item and tech and in rare cases, it can affect the entire party, making things very dangerous.
* NintendoHard:
** If the player doesn't spend a good amount of time grinding for experience and money for gear and upgrading their mobile suits, many of the bosses will be difficult to defeat. It doesn't help that at the beginning of the game, enemies don't drop an awful lot of either, so it could be a few hours before being ready to defeat the bosses without much trouble.
** The final stages of the game and the bonus bosses. The latter can easily kill you in one hit.
** Another thing to note is that if the player travels far east from Eisengrad before defeating the first two generals, they'll have a chance of running into a Gouf Hammer, that can kill them quickly if their mobile suits aren't that great, but they do drop 800 XP and occasionally their hammer which itself is very powerful.
* ScrappyMechanic:
** Thinking about which mobile suit will work best with each character since all of the characters have different stats. One character will have higher melee stats than ranged, so figure out which mobile suit deals the most melee damage and vice versa with characters that have higher ranged stats than their melee ones. What also makes this tedious is that gear the player obtains like shields and guards can also increase a mobile suits stats along with the optional parts to equip and wielding certain items like claws and missile arms prevents the player from equipping regular melee weapons to mobile suits.
** Level grinding is almost a necessity because the player needs to defeat enemies to obtain money to not only to buy gear for mobile suits, but to also upgrade mobile suits to increase their strength, hit points and speed. Early on, enemies don't drop an awful lot of money and even when the player gets to a point where enemies are dropping more than before, the gear in every new town is better and therefore more expensive than the gear available in the last town.
** Switching party members can only be done at save points (found in dungeons) or by talking to Marie at her house. Thankfully, the player doesn't need to worry about this until pretty late in the game, but this can be very annoying when buying gear and upgrading[=/=]customizing MS because since the player can't see the stats of characters, they have to switch them out to keep up with upgrades and for deciding the best gear for characters to use. To make things worse, out of the six party members, four are [[RequiredPartyMember Required Party Members]] ([[CantDropTheHero Tristan]], Fritz, Aeon, Tremmie and briefly with Renzer late in game)[[note]]at least until you beat the game[[/note]] for being plot-relevant and having voiced dialogue during cutscenes.
* TearJerker: [[spoiler:Gavenger's death]] and Tremmie's reaction to it - especially with her fully knowing that [[spoiler:it was her brother's betrayal that got him killed]]. The soundtrack [[https://www.youtube.com/watch?v=6N3jFGlEAFM during]] and [[https://www.youtube.com/watch?v=1rUUTZDU4WI after]] doesn't help either.
* ThatOneLevel: Justified with the Dark Alliance Base, the DiscOneFinalDungeon where the party confronts the last member of the Dark Alliance. It's a icy mountain loaded with troublesome enemies blocking your path (some have short-circuit inducing attack, others are resistant and immune to certain attack-types). The boss, Big Zam, is ThatOneBoss: immune to beam-type attacks and can OneHitKill a fully healed defending party with his strongest Beam-based Boost Attack that he '''loves''' to spam.
