History YMMV / Ultrakill

* CrossoverShip: V1 is sometimes paired with V from WebVideo/{{Murder Drones}}, since they both are psychotic robots with a literal bloodlust.

** ULTRAKILL players tend to be fans of WebVideo/{{Murder Drones}}, probably because both works introduces robots with literal bloodlust.

** Gabriel's line "Come to me", right before the climactic fight in 6-1. It's obviously supposed to be a challenge to V1, but the breathy way he says it and especially the increased FoeRomanceSubtext from his rematch make it feel like he's either telling V1 to masturbate while thinking of him or to physically come to him [[{{Robosexual}} so they can have sex]].

** [[BrutalBonusLevel P-2, Wait of the World]]. [[spoiler:Were you expecting a [[BossOnlyLevel leisurely stroll to the boss gate like in P-1]]? Too bad! P-2 features some of the toughest enemy encounters in the entire game, including a tiny room filled with four Cerberi and a Ferryman, a fight with two Sisyphean Insurrectionists at once, an encounter with a pair of ''idol-protected [[DemonicSpiders Mindflayers]]'' where the idols can't be destroyed until clearing the room of additional enemies, and a final battle with an idol-protected Stalker who walks around covering enemies in sand until you defeat them all and expose the idol. Did we mention said enemies include ''four Sentries, four Virtues and a [[DegradedBoss Hideous Mass]]!?'' And those are the ''warm-up fights for the actual boss of the level, Sisyphus Prime.'' This level will put everything you've learned so far to the test and then push you further, and you'd better pray you make it out the other side. It was so hard, in fact, that the devs put out a patch a few days later to reduce the difficulty]].

** It's very, very common to never see players pull out the Knuckleblaster at all ([[AntiMetagameCharacter except to deal with Guttermen and their shields as of 7-2]]) and rely exclusively on the Feedbacker because of how ludicrously useful parrying is against almost every enemy in the game and how many style points can be accrued via parrying, as opposed to the limited use the Knuckleblaster has as essentially just a shotgun with higher knockback and a worse reload.

** The '''Minotaur''' from 7-1 is an extremely aggravating and difficult encounter in at ''least'' its first phase, to say nothing of its second. It's easily capable of three or four-shotting V1 as well as [[PlatformBattle knocking them off the moving carts and further damaging them]], and due to being a Demon doesn't release that much blood when being hit, meaning the only way to heal is to wait for some {{Mooks}} to pull up on another cart. This in and of itself is incredibly distracting and aggravating if you keep dying while trying to heal up or getting thrown off the cart, but the Minotaur is also capable of removing some your safe ground to work with, forcing you to multitask and carefully manage dashing between platforms while avoiding the Minotaur's blows. Then when you ''finally'' think you've won, you must face its second phase which while easier in terms of healing is still an incredibly tense and stressful battle as the Minotaur gains much quicker attacks and longer combo strings.

* SelfFanservice: The protagonist, V1, has gotten some... [[RuleThirtyFour interesting]] fan art, despite being a sexless KillerRobot who is only ever seen from a first-person perspective in-game [[spoiler:until [[SecretLevel 4-S]]]]. In fact it's not uncommon for fans of the game to make jokes abut Thicc V1. The devs are acutely aware of it: Gabriel's voice actor has referred to them [[https://youtu.be/2C14eZVnzBE?t=17 as a "hot robot"]], official merchandise exists of a [[https://newbloodstore.com/products/ultra-body-pillow-case?_pos=4&_sid=db17c55d7&_ss=r V1 bodypillow]] [[ReadyForLovemaking lying in bed with a rose]], and in-game, [[spoiler:the third bonus level is a visual novel starring V1, or at least an AlternateUniverse version of V1, as the main heroine wearing a ''SailorFuku'' of all things]].

** King Minos, due to being the only unambiguously heroic character in the setting, having a [[TheWoobie sympathetic backstory]], and [[spoiler:his memorable boss fight, which is generally considered as one of the best in the game, alongside being played by fan-favorite voice actor: Stephan Weyte.]]

** "Don't touch any water" in 5-1, a level whose largest rooms are entirely ''filled'' with the stuff. After finding the hidden valves (or, more likely, [[GuideDangIt looking up a walkthrough online]]), you can drain the water in the underwater rooms; however, it doesn't drain fully, giving you very small sections of dry floor. Also, the game still remembers if you touch water after a reload from checkpoint, so any mistake means redoing the entire level. Did we mention there are shallow, easily missed pools of water in the last room of the level, along with swarms of Sentries that force you to stay on the move?

* IKnewIt: Pretty much the entire game's playerbase assumed that the boss of P-2: Wait of the World was going to be [[spoiler:Sisyphus Prime long before the Prime Sanctum was added into the game, given how King Sisyphus carries the same amount of narrative weight in Greed that Minos carried in Lust, and V1 can find his corpse in the secret area of the pyramid in 4-4 where they find the Sawblade Launcher and it's just as big as the Corpse of King Minos, denoting that Sisyphus had a prime soul.]]

** Guttertanks are deceptively speedy and evasive for their size and typically fight from a distance. They'll pelt you with lightning-fast missiles or landmines, the latter of which having a tiny parry window, and these explosives inflict heavy knockback. Within melee range, they have a quick, powerful punch with the same strong knockback as the explosives, and it cannot be parried unless the Guttertank misses and trips over. One Guttertank is already a headache, but they commonly spawn in groups that can easily juggle an unprepared player. The Freezeframe Rocket Launcher can freeze their rockets to make things a bit easier, and there's even an instakill trick in which you can ride one of their rockets back into them, but it only can help so much. Before a patch, these enemies were even worse to deal with; they didn't trip upon missing a punch, meaning they could rapidly follow up on a missed punch with another, thus making healing off of their blood overly risky.

* MoralEventHorizon: [[spoiler:[[BigBad Hell itself]] already proved itself as a vile, depraved villain of unimaginable cruelty by slaughtering the human race to claim their souls and torture them for all eternity out of [[{{Sadist}} sadistic pleasure]]. But if an atrocity like this didn't cross the line for some players, then maybe its cruel treatment of one of its Demons will, such as leaving [[TragicMonster The Minotaur]] to rot in the Garden of Forking Paths for a millenia before [[HopeCrusher crushing]] its TragicDream of seeing the sky one last time by leading it to the level exit before [[EvilIsPetty immediately closing the Hellevator doors it just opened]], forcing it in a losing battle against V1 where the Minotaur dies with regret for failing its dream. Hell is so evil that not even ''its own Demons'' are safe from its cruelty.]]

** Mindflayers have an assortment of abilities that make them difficult to fight at any range. They can teleport, fire either homing projectiles or a sweeping laser, and swipe with some strong melee attacks. They're surprisingly bulky despite appearances, and while they have some weak points, they're difficult to hit thanks to their size and the Mindflayers' movements. It's telling that most experienced players say to burst them down with the railgun and the nailgun before they even get a chance to really get going. You can temporarily prevent them from teleporting by hitting them with the Screwdriver variant of the railcannon, but this only mitigates the threat they pose slightly. You can also kill them instantly by using weapons that deal SplashDamage (such as the Malicious Railcannon, parried Shotgun pellets, the Blue Shotgun's Core Eject, the Green Shotgun's Max Pump, and the Knuckleblaster) to [[HoistByHisOwnPetard reflect their blue projectiles back to them]], but pulling this off is difficult.

** Mindflayers have an assortment of abilities that make them difficult to fight at any range.

** Mindflayers show up at the middle of level 2-3 and become an annoyance for the rest of the game. They're able to teleport around, fire hard-to-parry projectiles that deal a ton of damage, and strike at you with powerful melee swipes. No range is safe for fighting them, and their high mobility and damage means that striking at them with the shotgun to recover health is often extremely risky, especially when their meaty health for what's supposed to be a mook allows them to last very long compared to most enemies. Mindflayers have hard-to-hit weakpoints, but thanks to their fast movement, consistently hurting them is difficult.
