Museum Explorer Achievement in The Talos Principle II

*MISSABLE*

You will go to New Jerusalem three times during your playthrough, and therefore have three opportunities to unlock this achievement.

The Museum of the Simulation is directly opposite the town from the elevator, and you'll be required to go as part of the story. There are only three areas to visit:
 

1. One to the left, where the computer terminal is
2. One straight back, where the puzzle recreations are
3. One to the right, where the tetromino puzzle recreations are

Simply walk in each area to unlock this achievement. No need to solve the puzzles for any achievements.
