- Awesome Music:
- When the Lights Went Out by Whitey, the ending credits theme. As a bonus, it's the final track off the album Seven.
- In the beginning of the "Big Boo's Hunt" level, the pitched down version of "El Mañana" by Gorillaz will play on the radio, very fitting for the game's atmosphere.
- The use of the Cove and Ruins OST from Darkest Dungeon during the final gameplay segments is also a neat touch.
- Breather Level: The train sequence, in which Luigi enters the Mushroom Kingdom for a short time. No enemies, and instead you've simply got some platforming to do.
- Demonic Spiders:
- The Koopas are reskins of the Combine patrol, except the difference between this mod and that game is that here you are stuck with either melee weapons or no weapons at all during certain levels.
- The Headcrab shells in the final level, which will instantly kill you if you're too close to the incoming impact. Don't forget the flying Mario heads (Manhack reskins) that will attack you at the very end of the said level.
- Fridge Horror: So who was it that gave him the thing used to lockpick the door, therefore kickstarting everything?! Did they know what they'd unleash?!
- Funny Moments: The easter eggs, almost all of the easter eggs. See them here.
- It Was His Sled: If you've seen the original Terminal 7 skit, you'll already know The Reveal that Luigi is dying of Terminal 7 brain cancer, causing him to hallucinate all of his adventures with Mario.
- Moral Event Horizon: Luigi kidnapping Peach and either killing her or simply neglecting her until she starved to death might be considered one.
- Spiritual Successor: Can be considered one for Manhunt 2. Both games feature a Woobie, Destroyer of Worlds Villain Protagonist who escaped a mental facility guided by their own insanity and suffering intense hallucinations. The second level and the last half of the first of Terminal 7 take the game to a stealth direction (including the "hide in the shadows" mechanic that Manhunt used), and the game uses a track or few from Manhunt, so the connection might be intended.
- Tear Jerker:
Luigi: No more Daisy... (suddenly forlorn) No more Daisy.
- Luigi finding Mario's hanged corpse. Likewise, the voice acting that Vinny gives in his video on the game range from blubbering to anguished Screaming Warrior to capture the moments that the game gives. The fact that he has conversations with a "Mario" who tries to tell him his delusions aren't real before finding his brother's corpse implies that he's hearing a voice in his head that not only sounds like his brother but also shows that deep down he knows he's delusional.
- Vinny's voice acting for the game also paints Luigi as an Obliviously Evil Tragic Villain seeing the world as it truly is as his Terminal 7 consumes him. His reaction to seeing the illusion of Peach's "Castle" fade away to reveal it's just a worn down cabin in the middle of nowhere that he just left her in is one of the most heartbreaking, as is the beginnings of his Heel Realization as he communicates with what seems to be the voice of Mario in his head.
- The final level where Luigi's mind breaks down. At the very end, you can see Luigi lying on a table with what appears to be Mario and Peach crying over him. Either Luigi is in a Dying Dream and is experiencing his final moments or it's an earlier memory where he was diagnosed with brain cancer.
- Vinny manage to make that one tragic too by having Luigi shift between yearning for his fantasies and violently rejecting them. However, one of his rejections stand out as Luigi seemingly realizes that Daisy may have just been a figment of his imagination.
- That One Level: The sewer level is incredibly hard considering the shift from an action packed First-Person Shooter to a stealth game, and it shows. Weaponless, you have to navigate tight corridors to avoid Koopa Troopas, who will gun you down easily if you so much as step out of the shadows. And straight-up confrontation is all but required for certain segments. Have fun.
- The Woobie: It's simply just hard to not feel sorry for Luigi when all is said and done.
- That's to say nothing of his brother, Mario. A cynical plumber who desperately tried to help his brother by turning him into a mental hospital. Instead, not only did Luigi get worse, but the constant (and expensive) medical bills essentially bankrupted Mario to nothing.
YMMV / Terminal 7
