YMMV / Ratchet & Clank: Up Your Arsenal

  • Anti-Climax Boss: The final boss, which can be fought using a hovership. The problem is all of the boss's attacks are telegraphed and are slow-moving projectiles, so they're easily avoided with the same strafing and dodging techniques you've used in previous hovership missions.
  • And You Thought It Would Fail: The games turbulent production and rushed content made the staff at Insomniac Games genuinely worried that the game would be a flop, with one staffer saying it was seen as a disaster just two weeks before it went gold. They were completely blindsided by the game being a huge critical and commercial success.
  • Best Boss Ever:
    • The final boss fight against Dr. Nefarious is an awesome, intense fight. After the extreme difficulty of Drek and the pushover of the Giant Protopet, Nefarious hits the sweet spot between the two, possessing attacks that force you to stay on your toes, and won't punish you overly if you mess up. It's nice in concept as well — Nefarious might be a bumbling fool while in cutscenes, but when he's forced to fight, he's very capable of holding his own.
    • It also applies to his Dragon, Courtney Gears, notably because of how different the atmosphere of the fight is. The setup to it, the passage through Obani Draco is already cool, basically equaling to entering something akin to artificial moon, with reproductors and sound equipment everywhere, but the fight really takes the cake. In the cutscene before, she turns Skidd into a robot and captures Ratchet, showing him how much of a sadistic monster she is. He's furious! It takes place on her singing stage, first with her dancers attacking you, then her taking on you, all happening while Death to Squishies plays.
  • Best Level Ever:
    • The assassination mission on Planet Aridia. With great music and an expansive environment, there are many ways to approach this level, whether it be using sniper rifle stealth or just outright going in with a destructive vehicle.
    • The Obani Draco, because of how different it is from basically any other planet in this and previous games. It looks like artificial moon overloaded with sound apparature and even having enormous disco ball at one point, which you enter. Then the location is topped of by Boss Battle with Courtney Gears right after her Moral Event Horizon.
  • Ear Worm: Just try to get that Courtney Gears song out of your head. It doesn't help that it gets both a Boss Remix and a Groovitron remix in Tools Of Destruction (which is only in the Japanese version, though).
  • Even Better Sequel: It takes Going Commando, trims the fat, and refines the heck out of everything else. Add the surprisingly good multiplayer, and the result is a game that's usually regarded as the best of the series. The only general complaints are how short and easy it is compared to the previous games.
  • Game-Breaker: In contrast to Going Commando's first-game weapons, all of the Old Save Bonus weapons in this game are extremely powerful. By extension having old save is this, because it allows you to get these weapons for free while normally they cost as much as 250 000 bolts apiece, meaning you can save your money on resident Armor of Invincibility:
    • The Mini-Turret glove launches an automated turret to attack, the turrets are powerful, target enemies on their own, are invincible, and you can have several out at once. The only downside is the limited ammo, but it's so good that you'll mostly only need to use one to take out a group of enemies anyway.
    • The Lava Gun can still destroy enemies quickly, and retains its constant stream properties when it upgrades this time, meaning that it remains an excellent crowd controller.
    • The Bouncer retains this status from the previous game, despite having less ammo this time around. It can clear out a group of enemies with the initial bomb, and if another group comes in, they'll be taken out by the bomblets left behind. It also works extremely well on powerful enemies.
    • The Plasma Coil isn't too bad initially, but once it becomes the Plasma Storm, it fires an orb that zaps everything in its path. Little enemies have no chance of reaching you, and one or two more will take care of the rest with ease.
    • The Shield Charger outclasses the Holoshield in every aspect, as it surrounds you directly as opposed to putting up a stationary barrier. It can soak up a lot of damage, so stray fire isn't as threatening. Once it becomes the Tesla Barrier, it'll also zap any nearby enemies, meaning that you don't have to worry about the weak ones anymore.
    • From the new weapons, Rift Inducer. It shoots a black hole that sucks all small to medium-sized enemies within its reach (basically most of them), including Tyrrhanoid Captains who border on Demonic Spiders otherwise.
  • Genius Programming: The game originally shipped without any method of patching it, which proved problematic for a multiplayer game. However, Insomniac managed to patch the game anyway by essentially hijacking the EULA. It must be read to be believed.
  • Goddamned Bats: The Amoeboids in the sewers at Aquatos. They are everywhere in the tunnels and the bigger Amoeboids will split into smaller ones if you hit them. If enough of them are killed in quick succession (usually when leveling up weapons), the game will slow to a crawl until you leave the sewers.
  • Harsher in Hindsight: One of the announcer's lines in Annihilation Nation is "This Lombax clearly had a rough childhood!" Considering what we learn about Lombaxes in later games...
    • Also, Angela Cross appears in the cinema audience at the end of the game in her thief disguise. She's later confirmed to be a Lombax, so there's an in-story explanation on why she just didn't appear in her normal attire.
  • Hilarious in Hindsight:
    • The vid comic narrator expressing utter disbelief at the concept of "robotic pirate ghosts", which end up being the main enemies in Quest For Booty.
    • In a similar vein, Clank's utter bewilderment at Nefarious thinking he's a real secret agent rather than just an actor who plays one. The (questionably canon) Secret Agent Clank spin-off would later take the idea of Clank being an actual secret agent superspy and run with it.
    Clank: I believe there has been a misunderstanding. Secret Agent Clank is merely a fictional character I play on the holo...
    Nefarious: LIES! SQUISHY LIIIIIIII-(fft)-"Oh Lance..."
  • Ho Yay: One of the last cutscenes of the game shows Skrunch trying to kiss Clank. The response: "Do not even think about it!"
  • Idiot Plot: Deliberately invoked as far as Secret Agent Clank is involved, as most of the galaxy thinks the show is for real and that Ratchet, who does the vast majority of the grunt work is really nothing more than a clumsy chauffeur, and instead call upon Clank alone to deal with Nefarious. Unfortunately, it is the show that draws Nefarious, himself believing it to be real, to pursue Clank to join his robot ranks only to replace him with Klunk as his double when Clank refuses, causing a great deal of trouble for Ratchet and his friends.
  • Moral Event Horizon: While nether Dr. Nefarious nor Klunk cross this line (yet, in the latter's case), Courtney Gears does by betraying the Q-Force, abducting Clank and turning Skidd into a robot. Not only all that, she's a bit too sadistic when Ratchet fights her later on.
    • Captain Qwark nearly crosses this line when he fakes his death, and cowardly refuses to rejoin the fight. He manages to avoid this line in the end.
  • Power Up Letdown: The final upgrade to RY-3-NO. Instead of shooting a volley of energy blasts, it simply obliterates everything on screen. This creates a problem when you swing a camera, because when enemy disappears from your view he isn't destroyed. Another letdown is upgraded version isn't useful against bosses. At least its ammo is cheaper than Zodiac's.
  • Rescued from the Scrappy Heap:
    • Lava Gun. Its final version in previous game wasn't liked due to losing the continuous stream that was its best attribute. Here it keeps it, staying great crowd controller during the entirety of the game.
    • To a lesser degree, Disc Blade Gun. Some people complained about its spiritual predecessor in Going Commando, Chopper, because Ratchet couldn't move when throwing stars. Here Disc Blade Gun shoots them instead and thus doesn't have such kind of problems.
  • That One Side Quest: The Qwark vid-comic time trial skill points can be a pain to get through, as they require precise platforming and dying doesn't restore the lost time, meaning that even one death can fail the challenge. The worst of the bunch is the last one, where you have to contend with raising boiling acid and some platforms have moving purple sludge on them, meaning you might have to wait until you can safely jump on them if you don't want to get hit, which you can't really afford.
  • They Changed It, Now It Sucks: The Hacker segments. In both of the previous two games, there was a gadget specifically meant for furthering your progression through a level, either by (literally) unlocking a new area or path or by fixing an electronic device that you needed to use. Whereas the previous games incorporated puzzles into the hacking minigames (Tresspasser, Infiltrator), or at least were over fairly quickly (Electrolyser), using the hacker isn't nearly as interesting or fun; in fact, you may find it to be pretty damn annoying. Even worse, in most instances each Hacker segment has multiple stages, meaning you'll have to beat the mini-game more than once to open most roadblocks.
  • Tough Act to Follow: Up Your Arsenal is generally considered to be the best game in the franchise, which is why Deadlocked and Size Matters initially didn't do so well (though while Deadlocked eventually became popular in it's own right, Size Matters is hated by a lot of fans for being a Narm Charm and is eventually declared non-canon).
  • Underused Game Mechanic: The Warp Pad is a gadget that lets you place a location to warp to at select points. There are 2 of these select points in the entirety of the game, which both appear in the same level. Even better, one of the sections can also be completed using the Charge Boots instead.
