Hellnight (Playstation) - RetroAchievements/guides GitHub Wiki
Guide by ImStef
| Set Difficulty | 2/10 |
| Approximate time to master | 15-20+ hours. |
| Minimum numbers of playthroughs needed | 2 full, 4 partial. |
| Number of missable achievements | 28. Any achievement that isn't story related can be missed. |
| Does difficulty affect achievements? | No difficulty options. |
For your first playthrough, I recommend keeping Naomi as your partner and giving the headphones to Sugiya. This will be the harder of the playthroughs, as Naomi doesn't gain a defensive item until the literal last area of the game, and Sugiya's route has 1 extra area compared to Mika's, but doing so will get the majority of achievements out of the way + set you up to make your next run(s) faster.
This is by far the easiest run, and should be a lot faster than your first. Kamiya has a pistol that can be used a total of 18 times, making speedrunning a lot easier. He is also the only character who's ending doesn't take you to the Altars at the end of the game. Combine that with Mika's route, and that's 2 whole areas you don't need to visit.
Finally, it's time for your clean up. If you set up your back-up saves properly and grab each partner in sequential order, their endings will come quicker and quicker. For convenience, I've marked exactly where to make each save throughout the achievement guide. The partner order should go as follows: Naomi, Kamiya (Bar), Kamiya (Pen), Ivanoff, Rene, That Which Wanders, Solo. If you missed any other achievements, now is the time to finish them.

- I've ordered and written the achievements below in the exact order you can earn them through natural progression so you never have to skip ahead or look for an achievement in the area you're in.
- Story related achievements have a brief description of when you should expect to unlock them, but I give no info on progression, as to not spoil anything.
- Missable achievements have explanations on what to do + a map showing the exact location you need to be. The map is hidden as to not spoil it for people who want to figure it out on their own.
- I've also labelled exactly where and when you need to make a back-up save for other partners, reducing the amount of full runs you need to do. There's only 3 save slots, so you'll need to manage these and continuously push new partner saves up as you clear off endings.
- Below the achievements section is a map section. Each one is fully mapped out and labelled with every item needed for progression + missable achievements. I recommend only using this on your 2nd run, or if you're really stuck and need an idea on where to go.
Safe Haven (1) Seek safety behind a pair of steel doors
MISSABLE
At the top right end of the first map will be a set of large metal doors. Open them, then head inside and close them to play a unique cutscene.
Metal Door
Hell of a Night (2) Escape the Underground Sewer
STORY RELATED
This will unlock after escaping the first map.
Imperial Soldier in My Bed (2) Deliver the Important Documents to Tsunoda
STORY RELATED
This will unlock after receiving the Mechanized Gate Key.
Warning
While you're in the Square where you get the Mechanized Gate Key, make sure you've spoken to "Sweeper" Leno. Doing so now is required for an achievement later on.
Warning
Make a back-up save in the 2nd slot after passing through the Mechanized Gate into the Northwest Area. We'll be reloading this for Kamiya and his achievements, as well as using this as the starting point for our 2nd playthrough.
You've Been Careless (1) Naomi has been taken by the monster
MISSABLE
Located at the top-left corner of the Northwest Area is a staircase. When you enter it, Naomi will warn you that she doesn't feel safe climbing it. Ignore her and do so anyways.
Stairs Location
Handsome Killer (2) Partner up with Kamiya in Little Jamaica
MISSABLE
If you currently have no partner (your previous partner was killed or taken by the creature), Kamiya will join you when you enter the bar in the Northwest Area. You need to come in here for a story item, so he's impossible to miss.

MISSABLE
Any time after recruiting Kamiya, return to the Southeast area and go to the hallway on the map that's the furthest west (refer to the image below). Once you arrive, a unique scene between Mario and Kamiya will play out.

STORY RELATED
This will unlock after opening and entering both hidden passages.
Tokyo Mesh Citizen (2) Acquire the Green Card
STORY RELATED
This will unlock after receiving the Green Card from "Pheromone" Mayumi.
Warning
- You can make a back-up save in the 3rd slot before choosing who to give the headphones to, but I recommend just loading your slot prior to recruiting Kamiya, as you'll need him in this area for an achievement. If you already have that achievement, this is an option.
- The next choice you make will set your game on a specific route. It doesn't really matter who you pick. Mika's route has one less required area than Sugiya's, so it's recommended to do Sugiya's first, get all of the missable achievements you can, then do Mika's on your next run.
Memorabilia (2) Return the headphones to Sugiya and get the Stairwell Key
STORY RELATED
This will unlock after giving the headphones to Sugiya. I recommend doing his route on your 1st run, as his route requires you to go to the 2F Factory Area. Doing this now can make your 2nd playthrough just a bit faster.
Can I, Like, Have ‘Em? (2) Give the headphones to Mika and get the Stairwell Key
STORY RELATED
This will unlock after giving the headphones to Mika. Make sure you interact with the key around her neck so she gives it to you. I recommend doing this on your 2nd run.

STORY RELATED
This will unlock after using the Stairwell Key to continue onwards.
Wait... I Know You (2) Re-unite with someone you thought lost
MISSABLE
This can only be earned if Naomi got taken by the monster in 1F Northeast Area, and you currently have no partner. When you enter the 2F Residential Area, run forward and eventually there will be a branching path on your right. Skip it and take the next one, then enter the door. Naomi will be resting inside and rejoin as your partner.

You can only acquire this if you're partnered with Kamiya and haven't triggered Maruho's event yet. After making your way to the Livestock Area, take the first path you can going north and an NPC named Maruho will appear. He'll get into an altercation with Kamiya, and you'll be given a prompt asking if you want to stop him. Choose "No" and a unique scene will play out.

Here you'll need to locate him again in order to progress the story. Once you find him, he'll mention talking to you before, and the achievement will unlock.

STORY RELATED
In the middle of the 2F Livestock Area, you can find an NPC named "Believer" Murami. When you talk to him, choose yes and answer his questions. There's no penalty for failing, so you can keep trying until you get the correct answers, but I'll list them below.

STORY RELATED

We Made It! (25) Finish the game with Naomi's ending
So It Was You Who Was Calling To Me... (25) Finish the Game with Kamiya's Ending
Mission Completed (25) Finish the game with Ivanoff's ending
I'd Rather Forget... (25) Finish the game with Rene's Ending
Forget All That Has Happened Here (25) Finish the game with That Which Wanders' ending
...What Exactly Was He? (25) Finish the game with the Solo ending
All of these achievements are awarded for finishing the game with each partner still alive. In my opinion, Naomi is the hardest, as you have to take her from the very start of the game to the very end, and she has no defensive ability until the very last area of the game (one that doesn't even work every time, mind you). As you progress through your runs and collect your next partner, make sure to manage your saves well so you don't have to do a full run for each character.
