Horatio's just finished a few repairs on the UNIIC, but there's no time to celebrate - something down in Engineering is making strange noises.
This brief introduction to the game sees you navigating the UNIIC and getting used to the basics of movement.
Unlike normal walkthroughs, in Nice Game Hints you can select just the puzzle you want hints for. Here are listed the puzzles for "Part 1 - Investigating the strange noise" in Primordia. The guide you choose only contains information about that puzzle, reducing possible spoilers for other puzzles.
