Introduction - Chex Quest
Introduction is a short percussion sequence that's played when the game boots up the title screen.
Chex Quest (DOS)
This is the first occurrence of the Chex Quest introduction tune. The song is named D_Intro in the WAD file, just like in Doom (DOS). There is also a special AdLib version of the song called D_IintroA, however, unlike Doom, the file is identical to the MIDI version.
Chex Quest 2 (DOS)
Although Chex Quest 2 is a mod that uses most of the original media from the original WAD, the Chex Quest 2 PWAD contains a second copy of the D_Intro and D_IntroA MUS files, even though they are identical to the first game.
