100 Things You Never Knew About Resident Evil

Resident Evil's usage of old material occasionally also extends to it's music. In the case of RE 1.5, as previously established, plenty of the OST got moved around the final version of RE2. The N64 soundtrack of Resident Evil Zero did indeed get used, even though the shift to a different hardware generation meant remaking most of it (although the save theme for N64 is totally different, and well worth a listen).

One of the best pieces of Resident Evil music occurs frustratingly in just one room in the original Resident Evil 2 and it's a room that's very easy to miss. If the player uses the fingerprint scanner across both A and B playthroughs they can enter a room in the lab where the track "Wreckage Of The Mad Experiment" plays - a dark, twisted theme that perfectly represents Umbrella's willingness to laugh in the face of morality for their goals.

So then, it was perfect to be reused in The Umbrella Chronicles as "Live Evil", a rock theme that is heavily associated with Albert Wesker.

Another RE2 track that triumphantly returns in future games is Ada's Theme, which beautifully plays during Resident Evil 6. Which is probably the only time someone as described anything RE6 as "beautiful" in any way.
