Perhaps the most infamous of all unauthorized Doom products, Laura Beyer's Doom was sold for $20 and featured nine maps, replacing the first episode (with an install process that modified the Doom IWAD), and coming with three "bonus" levels. I really don't know how much Beyer was actually involved in this work. She's listed as the "Boss (she made us do it!)" and the destination for game orders, but Mike "Laura's BOY TOY" Helm is the Head Programmer with Kody Zander and Darryl Dewald listed as the actual level designers. Certainly someone was responsible for the new graphics and sounds, a few of the latter I recognize as appearing in Eternal Doom (and many other WADs of the time). As to how the team assembled, it looks like almost everyone was (and still is) stationed in Creston, Canada, so I assume they were friends.
