History YMMV / TwentyXX

* SugarWiki/AwesomeMusic: ''Oh yes.'' Hear it in it's full synthetic glory [[https://soundcloud.com/cityfires/sets/20xx here!]]

* AwesomeButImpractical: The prototype augments often give you massive bonuses but not with an equally heavy penalty and you can get more than one. Some of the characters can work around the handicaps, but woe is the unaware soul who picks the wrong prototype at the wrong time. To give some examples.
** Hawk's World Igniter has bar none the highest [=DPS=] of the entire game. The catch? It is ''extremely'' energy consuming and even with Owlhawk's Focus (which reduces special ammo consumption in 50%) it will eat through your energy gauge before you can finish saying ''[=Twenty-Double-X=]''.

** Level 9 is a ''very'' long gauntlet loaded with all the obstacles and hazards of all the previous stages. It also has some very long periods without solid ground, even more than Skytemple, and as a result you can get sent quite a ways back if you fall into a pit. To make matters worse, crates, item chests, vending machines, and shop teleporters are all very sparse or nonexistant until you reach the boss door. You'll have to make do with what drops from enemies here. Notably, the stage after this one is a bit easier due to fewer pits and the presence of crates and vending machines within the stage, though it does feature a much nastier boss.
* TheUntwist: [[spoiler:You mean those two {{Jerkass}}es who constantly insult and belittle you no matter how well you do, condescendingly refer to you as [[ItIsDehumanising "it"]], try to screw you out of your payment twice, and are clearly expecting you to die horribly, are ''the bad guys?'' Who would've thought?]]

* SugarWiki/FunnyMoments: Text pops up when you pick things up, often including some sort of joke, but the prize has to go to the interaction of the Kingseeker prototype aug ("Bathe in glory") and the System Restore, which purges its downsides ("Bathe however you like!")

** As for Powers, the Shadespur is often skipped for the [=Nutstack/Aug=] bonus. This is mostly due to the weapon's main gimmick - it fires in the direction that the Contractor moves in. This makes it very awkward to use, especially when jumping or landing, and not to mention its range is limited by your speed, a stat which players tend to invest little in unless they're speedrunners.

** The Wave Beam for Nina. It does have a natural wall piercing ability, but its wavy pattern makes this weapon unreliable to take out small critters like Flapps or Bzzombs reliably, not to mention that wall piercing can be rendered redundant is by the Quantum Spook augment.

** Agnisort, Perforator Alpha and Rollster Beta's stages on Levels 7 and 8 tend to be quite problematic if you don't have good augments. The level is generated in such a way that you will always have to battle large groups of enemies in cramped spaces or at unfavorable ground with stage hazards getting your way. Without Quantum Spook to hit through walls, or some way to quickly destroy enemies you might get hit a lot while fighting the enemies. While Nina can have a break with her long range, Ace will almost always struggle with this level since only one of his weapons has decent range.

* GoddamnedBats: Gamma Flapps. You'd expect the whole Flapp line to be nothing but goddamned bats, but normal Flapps and Betas are more cannon fodder enemies than anything. It's the Gammas that are annoying, what with their ability to suddenly dodge attacks-- and they are very good at it. Unless your attack is at point-blank range, expect the Flapp to suddenly dodge out of the way before charging at you. [[note]]Apparently Flapp's infamy did not go unnoticed as version 1.3 added the "Unflappable" augment which renders them harmless.[[/note]]

* AwesomeButImpractical: The prototype augments often give you massive bonuses but not with an equally heavy penalty and you can get more than one. Some of the characters can work around the handicaps, but woe is the unaware soul who picks the wrong prototype at the wrong time. To give some examples:
** Zookeeper's Burden gives you one of each Repro instantly (two if you had Splintering Twinifier beforehand), however you will not be able to attack or use powers at all.
** Focusing Sagelens ''doubles'' your special weapons power damage, however it plummets your attack to '''''-18''''' meaning they will deal only 1 damage.
** Violence Enhancer gives +5 to attack and power, but you take ''double'' damage. This can stack with the Wrath challenge skull which also makes double damage.
