YMMV / The 3rd Birthday

  • Base Breaker: Aya's apparent Chickification, although the truth is more complicated...
    • Contested Sequel: Some snarky fans sum up their feelings about this game by saying that it's not even a proper sequel at all; it doesn't even have "Parasite Eve" in the title, for example.
    • More than the Chickification and fan snark, much of the ire towards the game stems from its nearly incomprehensible storyline and near retconning of the entire series as a whole.
  • Crosses the Line Twice / Silliness Switch: Aya's alternate costumes? Unappropriate fancervice. Their over-the-top campy alternate voiceover? Beyond hilarious! Sadly, Japanese version only
  • Crowning Music of Awesome Most the OST,what's with Yoko Shimomura having worked on it.
  • Demonic Spiders / Boss in Mook Clothing: Any Twisted beyond the first few species can be this, but the Rovers, the Mudflaps, and the Worms definitely qualifies.
  • Game Breaker the Berserker weapon obtained late in the game to fight the Reaper due to Good Bad Bugs,and we'll leave it at that.
  • Goddamned Bats: Wads and Beans, hands down.
  • Les Yay: Gabrielle says some weird stuff about Aya wanting her, though Aya's just confused by what she's talking about, making it sound like Gabrielle's projecting.
  • Squick: Beat the game, then think about that shower scene. Technically, Eve's still VERY much underage, and even with clone genetics being what they are, she still doesn't quite look legal...
  • Stop Helping Me!: The Boss's directions are like this when he takes over near the end of episode 2, especially annoying since his voice is so Obviously Evil.
  • Tear Jerker: The Reveal. Eve was already a woobie when she was created in the second game; after she finally had the chance of happiness, it was all taken away in a snap, and she even cause all the incidents to happen. It's just... Heartwrenching. At least she gets a chance to live peacefully in a Twisted-less timeline at the end of the game, but that timeline was brought about thanks to a Heroic Sacrifice on Aya's part.
  • That One Boss / Wakeup Call Boss: Easily many of them are, depending on how well your DNA board is customized and how well you've kept up with upgrading your weapons.
  • The Woobie: Eve. The poor kid is in dire need of a hug. She just wanted to save her sister, but she inadvertently started a whole mess of other problems.
