Differences from final version#
Music#
- Pressing Start on the main menu mutes the title screen music.
- The Briefing Files menu does not have music.
- The background music that plays during the first Codec call is different, and it's completely absent from the final game. Notably this track does not have a loop point, rather it has a baked-in fade out effect and then repeats.
- The Underground Passage theme is the same as the final version but without sound effects.
Items#
