Replaces the game's sounds with the oldest version of each, taken from old releases of Factorio (0.6.4 to 0.17.79).

- Machine, enemy, weapon and footstep sounds
- Interface sounds
- The old soundtrack on Nauvis

Each sound uses the oldest version that had it. Sounds that never had an old version, such as picking up and dropping items, stay modern. On Space Age, other planets keep their own music.

Old and new sounds weren't balanced against each other, so some may seem louder or quieter than you're used to.

Works by itself or with Old Factorio Graphics.
