- Accidental Innuendo: "Don't come! Don't come!"
- Awesome Music: The Magician and Emperor's boss themes.
- Don't forget Mother!
- Contested Sequel: With regards to the Typing spin-offs, Overkill. While it's still the same B-movie hilarity as its original counterpart, only with typing instead of shooting, they lack the unique boss gimmicks of previous games — most of them are just a continuation of the "type stuff to damage them" premise rather than posing unique challenges.
- Demonic Spiders: There's bound to be at least one or two per game. The Hermit and The Lovers are literal examples (though they're bosses, so they don't really count).
- Pukers in OVERKILL definitely qualify. More specifically, if they are killed by anything other than a head-shot, they explode. If they are too close to you when they do so, you will take heavy damage. Ironically, if you let them grab you, it's easier to shake them off before they damage you — which is fatal to them without doing anything to you. The problem is shaking them off while other mutants move in...
- The last boss spawns them, and they break your view — you can't shake them off, and you have to give them about five seconds of sustained fire to make sure they're dead for sure. Most of the time, they'll be stunned, then resume barreling towards you.
- Ensemble Darkhorse: The Magician.
- Varla Guns. The PS3 version of Overkill even has two exclusive chapters where you play as her, because people loved her so much on the Wii version.
- Family-Unfriendly Aesop: "Remember, there's no such thing as a second chance". Also a Broken Aesop since this is said after Judgment's second chance, as well as Hypocritical Humor because of the fact that you can use continues.
- Goddamned Bats: Every. Single. Game. In addition, HOTD 2 manages to add the even-more-annoying kamikaze zombie owls alongside energetic, knife-handed midgets.
- Overkill adds in exploding
zombiesmutants, that, if you don't nail with a headshot, will damage you immediately. The last boss spawns them endlessly.
- Overkill adds in exploding
- Memetic Mutation: Sega and Namco shooter translations seem to feature a running joke of having hostages shout "Don't come!" They've been doing it for years, bless them.
- The infamous "Suffer like G did?" line in HOTD 2. It would have been imposing if the creature hadn't presented it as a question. And didn't have such a high voice.
- Most Annoying Sound: "RELOAD! RE-RE-RE-RELOAD! R-R-R-R-R-R-R-RELOAD!"
- The grunts and groans when a character is injured ("AGH!") also count.
- Narm: "The original sin that man is resphaansible to... To protect the loyfe coycle! I have maaaig a creacher to rule over maaahn kiiine! This is tha faynl bawdl! Shoe yourself! Our new ruler, the Empurr!" *followed by the camera pointing at a wall*
- In fact, anything anyone says in House of the Dead 2 (and there's plenty of examples in the other games as well). There's enough to fill their own page. How could anyone do that?
- Nausea Fuel: Fail to stun Temperance during his first phase and he jumps up and butt-stomps you. Eww...
- Player Punch:
- James getting hit by one of The Star's finishing attacks at the end of 4's fifth chapter. He is seen in several cutscenes in the next chapter limping and having to be physically assisted by Kate.
- Varla's brain transplant and her body's subsequent mutation in the final chapter of Overkill.
- So Bad, It's Good: The voice acting and translation, particularly in the first and especially the second game. "Don't come! Don't come!" "Suffer like G did?")
- "G's bloodstains!"
- Done intentionally for such purposes in Overkill.
- And, of course... "HM HM HM HM HM. PEE-PLE-OFF-ZE-AY-EM-ASS. AI-EMM GOLDMEN!"
- Squick: Fat zombies that can have holes punched in them, incest in Overkill, open beating hearts... there's frequently stuff one shouldn't dwell upon. Some of the water zombies in House of the Dead 2 look like they could be Tarman's clone, and Tarman is rather Squicky to a lot of people.
- Then there's more of Overkill, where we have macabre, disgusting bosses like the freaks in the Carnival, the Lobber, and Mother itself. It doesn't help that when she spawns mooks from her... erhm... womb, it looks like she's defecating. Also Warden Darling kissing his old, withered mother on the lips and Varla after her operation, with Mother's brain sticking out of her head. After the final boss fight, Darling also tries to atone by returning to the womb. Literally.
- Surprisingly Improved Sequel: While all of the games in the series are generally good, III is notable in that the voice-acting took a serious level in competence. By 4, it's easy to forget the earlier games' Narmy goodness.
- That One Attack: Ask anyone who has endured through The Fool's final attacks.
- That One Boss:
- Magician, Wheel of Fate, The Fool, The Emperor, The Star, The World, the list goes on and on, really...
- It should be noted that in HOTD 3, each bullet a boss takes will empty more of its yellow Break Meter every time it succeeds in attacking you; a boss has its maximum "stamina" level at the start of the fight. The Fool's stamina is initially just BARELY low enough to where it is possible to halt it the first time if every shot is accurate, done as fast as possible, and you begin with a fully-loaded shotgun. As such, The Fool ends more games (or causes more continues/coins to be fed) than even the final boss. Fixed in the console versions, though.
- The Magician in The Typing of the Dead. His gimmick is simple: type phrases out like usual. Except, if you miss, he automatically hits you.
- They Just Didn't Care: Sega's downloading service has a bit of a typo for HOTD 2◊, saying it's rated EC (Early Childhood).
- What an Idiot: In House of the 4, during the ending, after The World has been beaten, it mutates even more, followed by James activating a bomb in his PDA powerful enough destroy it.
You'd Expect: For James to chuck that thing like no tomorrow, destroying The World so he and Kate can continue fighting the zombie apocalypse together. Even Max would have done the same if he was in James' shoes.
Instead: James performs a Heroic Sacrifice by diving right into The World with his PDA time bomb in hand, taking The World with him.
- Special Effect Failure: Some shots of the protagonists shooting at zombies in the first film were from the original game, with an "Insert Coin" message blinking on the screen!
- They Just Didn't Care: Nowhere does it become more apparent than in the "Funny Version" of the first film, where we see endless scenes of everyone involved in the production screwing around.
- Video Game Movies Suck: The first film has the dishonor of being the first game series Uwe Boll got to butcher.
