Hello Neighbor features a set of achievements that reward players for completing specific challenges or reaching certain milestones. While the exact list can vary slightly by platform, here are some common types of achievements and tips for unlocking them:

- Story Progression Achievements: These are unlocked simply by completing each Act (e.g., 'Act 1 Complete', 'Act 2 Complete', 'Game Complete'). These are unmissable if you finish the game.
- Stealth Master: Often awarded for completing an Act without being caught a certain number of times, or for a specific duration. To achieve this, focus on advanced stealth techniques, distraction, and learning the Neighbor's patrol patterns.
- Puzzle Solver: Awarded for completing specific, often complex, puzzles within the game. For example, 'Train Puzzle Solved' or 'Giant Chair Climbed'. Follow the main walkthrough for these.
- Explorer: Rewards for discovering all hidden rooms or interacting with a certain number of lore objects. This requires thorough exploration of every area, including those off the main path.
- Trickster: Achievements for performing specific actions against the Neighbor, such as 'Trap the Neighbor' (using his own bear traps against him) or 'Distraction Expert' (luring him away multiple times with objects).
- Speedrunner: Some achievements might challenge you to complete an Act or the entire game within a specific time limit. This requires a deep understanding of the game's layout and optimal routes.
To efficiently unlock achievements, consider a second playthrough after completing the game, focusing specifically on the requirements for each one. Many achievements can be combined, but some might require dedicated attempts.
