Grandpa - 100% Achievement Guide (Full Walkthrough)

Notes and Tips



  • Progress will never get resetted, you can die as much as you want and you'll always keep your items. 
  • Dying after picking up an item, will make you respawn with that item, so sometimes dying is faster than making your way back to spawn. 
  • Grandpa will always spawn at basement. 
  • Achievements unlock upon closing the game, they all should come naturally while finishing the game. 

Walkthrough



  • 1. Open the cabinet right next to the area where you spawned, green key will be inside. Grab it (E key).

  • 3. Now comes the hardest part in the game. Try to sneak around into the other room in this area, and head downstairs to find the basement. 

Note: Be careful here, Grandpa will always spawn in basement (after each death).

  • 4. Grab the chainsaw.

  • 5. After that, go all the way up to the 2nd floor, going through the area where you spawned and using the left door this time. You'll find a police officer body next to a door and a key, drop your chainsaw and grab that key. Use it with the door.
