Almost nothing is known about Simmons, other than his last name. Simmons does not talk in Half-Life: Blue Shift.
Half-Life: Blue Shift
He escapes early on during the Black Mesa Incident when he, Walter, Rosenberg, and Barney Calhoun teleport to the surface through the use of an old prototype teleport, after which they escape using a Black Mesa SUV. Like his fellow scientists, his fate remains unknown.
