I have yet to find correct guitar chords for Overdose so I decided to save the day and transcribe them myself.
Although it is much later in the Overdose era, now anyone can enjoy playing the chords accurately!

Chords used:
Fm  (bar Em shape on 1st fret)
Bbm (bar Am shape on 1st fret)
C   (bar A shape on 3rd fret)
Db  (bar C shape on 1st fret)
Eb  (bar D shape on 1st fret)
Cm  (bar Am shape on 3rd fret)

For a more simple way to play, place a capo on the first fret and click the "transpose" down arrow once.
