This is a walkthrough for beginners

- Difficulty is softcore
- Not suitable for speedruns or old school (cleared with only pistols)
- The strategy order is arbitrary.

- Most of the enemy spawn locations and item locations have been omitted

- The story is very interesting, so be sure to read the [Notes] if you find them
