Phan and Artist Lee Davis has made available his terrific 26-page comic from 2012 titled Phantasm: Transcendence. It's an action-packed affair that he both wrote and illustrated and includes appearances by Mike, Reggie, Rocky, Liz, Tim and the Tall Man. You can download the entire comic in PDF form from the Archives here. Visit Lee's website to see more of his work here.
The issue mentions being the first in a series of four issues, but this appears to be the only one. Fingers crossed that more issues emerge some day. Surely Phantasm couldn't be so unlucky as to have TWO separate four-issue miniseries stall after the release of the first comic?
If reading a PDF comic isn't your thing, you can watch a video version of it below with introduction from Lee.
