Getting All the Trophies in Nun Massacre
nun massacre is a messy little indie horror game that throws a lot of optional trophies at you, some of which are annoying by design. i spent about 11 hours across three playthroughs to get them all, so i figured i would document what actually works instead of whatever the top search result says. The baseline requirement is finishing the game once. Easy enough. You unlock the chapter select after any ending, which means you do not need to replay everything for the harder ones. The real problem is that some trophies are mutually exclusive depending on which ending you get, and the game does not tell you this clearly until you miss one. There are roughly 18 trophies total, and about six of them require specific actions during certain chapters. The game has no trophy list visible mid-playthrough, which is frustrating when you are three hours in and realize you never picked up a required item in chapter two.
For the completionist trophy, you need 100% collectibles and all main objectives. The collectibles are scattered through every chapter and some are behind simple puzzles that are easy to miss because the game does not highlight interactive objects very well. I missed three medallions in chapter four on my first run because the lighting is deliberately dark and the collision detection on a couple of shelves is slightly off, making them harder to spot than they should be. The fix was holding left stick toward the shelf while crouching, which pushes the camera closer and lets you see past the clipping issue. Took me twenty minutes to figure that out. After that I just mapped each collectible area on paper and methodically cleared them. For the no-death trophy, you cannot die at all during a single playthrough. This applies to all difficulty levels. On normal it is doable in about two hours if you memorize enemy patrol routes. The trick most people miss is that certain environmental hazards count as death, including the falling debris in chapter three and the flooding sequence in chapter six. You can reload at saves before those sections instead of trying to survive them on instinct. I wasted about forty minutes on the chapter three debris encounter because i did not realize i could back out and reload.
The hardest trophy for most people is the secret ending one. You need to make a specific sequence of dialogue choices in chapter five that the game never foreshadows. There are no hints on screen and the options look nearly identical. I ended up reading player forums after unlocking the normal ending to find out the correct path, then replayed chapter five with a save immediately before the choice scene. The choice persists through the rest of the chapter and determines the ending, so make sure you have a fresh save right before you talk to the nun in the confessional room. Some trophies are story-locked and auto-unlock. Those are straightforward. The grindy ones are the collectible hunt and the speedrun trophy, which requires finishing the game under forty-five minutes. That speedrun one is brutal on the first attempt because you have to skip almost every combat encounter and use a specific route through the east wing that most players do not discover until they have already explored the west wing. The fast route goes through the maintenance tunnel behind the chapel, but the door only opens after you solve a simple lever puzzle in the basement. You need to go to the basement early or you will be stuck trying to fight your way through the main hall. There is a known bug on the PC version where the trophy for collecting all audio logs does not unlock if you pause the game during a log playback within the last thirty seconds of a chapter. The game registers the pause as an interruption and skips the collection flag. I hit this on my second to last log and had to replay that entire chapter section. If you are going for full completion, do not pause during audio log playbacks. Just let them run.

Overall strategy: save before every major decision, map collectibles as you go, and do not trust the first chapter select screen to show you exactly what you have already unlocked. The game sometimes lags on syncing trophy progress between sessions. If a trophy is missing after what should be a complete run, wait a few hours and check again or restart the game entirely. The game itself is not particularly long, roughly six to eight hours for a full completion run with retries. The difficulty spikes in chapters four and five, and the optional boss fights are where most people lose their no-death runs. You can bypass several optional encounters without affecting trophy eligibility, so skip them if you are chasing a specific challenge trophy.
