* AssPull: Chance as Unit One. They don't even sound alike!
* AwesomeMusic: Just [[http://www.youtube.com/watch?v=0aTr00ZLAf8 ONE example:]]
* EarWorm: The ThemeTune from the original PSX trilogy.
* ExecutiveMeddling: ''The Omega Strain'' was originally going to be a multiplayer-only game. It wasn't until near the end of the game's development that the developers were told to add a single player mode..
* GameBreaker: The Air Taser, wihout a doubt. Infinite range, infinite ammo, considered a stealth weapon, can kill a helluva lot of baddies in relatively short time plus its fun to hear them scream and see them catch on fire.
** In ''The Omega Strain'', the E.P.D.D. (advanced version of the air taser) is arguably the best weapon in the game, as it has ridiculous range, and can sometimes punch through flak jackets (usually in two hits), meaning that you can kill almost ANYONE you come across.
* GoodBadBugs: In ''The Omega Strain'', enemies will sometimes appear with weapons stuck in their necks, making it impossible to shoot the player, who can run around without fear of being hit. However, it can happen to the player as well.
* HarsherInHindsight: In the second game of the original Playstation trilogy (released in 2000, set in 1999), about halfway into the game, Lian Xing arranges a meeting with a former partner, Gregorov, at a neutral meeting point: a techno dance club. But their meet-up is ruined by an attack on the club to try and assassinate Lian. And the date that this happens on in the mission dossier? '''09/11'''.
* ItsTheSameNowItSucks: A common complaint is that the original trilogy's barely changed over time, in both graphics and gameplay.
* MostAnnoyingSound: "Cobra is down! I repeat, Cobra is down!"
** "You're runnin/almost outa time! PICK UP THE PACE!"
*** Imani Gray is one of ''the'' most irritating characters in the ''Syphon Filter'' series, because she's constantly yelling/whining at you to do something, or to pick up the pace. [[spoiler: Which makes her death all the more satisfying]].
* NarmCharm / SoBadItsGood - The voice acting in the original PlayStation trilogy.
** On that note, can't remember if it's the case with ''1'' or ''3'', but in ''2'', Gabe seems to talk at least twice as fast as everyone else. It's both hilarious and very jarring.
* SuspiciouslySimilarSong: The song playing part 2's Club 32 sounds like a techno version of [[{{ABBA}} "Dancing Queen"]].
* ThatOneLevel - ''Syphon Filter'', along with ''VideoGame/MetalGearSolid'', was one of the first games in the modern era (starting with the PSX onward) to use stealth and cover tactics to accomplish a mission. Notable examples that could still frustrate gamers today:
** In Washington, D.C., there was the tennis court level where you had to make precise silenced-night vision sniper shots.
** The museum level relied on evading or shooting multiple mooks.
** The snow base level. You had to plant C4 on each of the base's fuel tanks while remaining unseen by the mooks. And the subsequent base tower level, which required you to have enough ammo to fend off a helicopter whose pilot shot automatic rounds at you.
** The catacombs levels were sprawling. Fun to play, but extremely open world for its time.
** The PHARCOM warehouses. Infinite spawning mooks and very confusing layout. Also, you have to use the infrared-style device to get what you needed to advance, which were not at all easy to find, and you were not at all told that you needed to use them.
*** True, but if you used the "god mode"/"unlimited ammo" cheats, you turn the warehouse level into a shooting gallery.
** The missile silo level required you to navigate a series of catwalks and metal beams to disarm the missile AND escape before it launched.
** The sewers in ''2''. Narrow passages, almost no cover, and infinitely [[RespawningEnemies respawning]] Agency EliteMooks randomly appearing both in front and behind you. A {{luck based mission}}.
** The bonus missions in ''The Omega Strain'' have you playing characters from the earlier games (Gabe, Teresa, Lawrence, etc.). Sounds cool, right? The problem is that these bonus missions can be quite long, have multiple objectives, are all stealth based, and if you get spotted, it's an instant game over. And because there are no checkpoints, if you fail, ''you have to start all over again from the beginning''[[note]]Technically, you can still continue the game if you're spotted in Gabe's mission, but it's next to impossible to beat in the time limit you're given[[/note]]. This is especially problematic in Lawrence's mission, where you have to sneak through a bombed-out village that has plenty of places for enemy soldiers to hide, and you can't kill any of them. The general consensus among Syphon Filter fans is that this is arguably the most frustrating mission in the entire series.
** Any of the stealth missions especially in part 2.
* TheScrappy: Imani Grey thinks she is [[TwentyFour Jack Bauer]] but ends up being a lot bitchier, constantly harassing and putting down the player, [[spoiler: only to end up killed early in the game.]]
