So no one gunna mention that this is the Doom Guy?

Doom had a small book series, and in it the protagonist marine was named Flynn Taggart.
It did. It wasn't very good, though, and I never managed to get my hands on the second novel in that series.
The character in Jupiter Hell is named Mark Taggart. You can see the name in the Tutorial :)
