Walter Bennet
City 14
A prominent member of the Science Team in the now defunct Black Mesa Research Facility, Dr. Bennet was involved in highly classified research in the facility's Biodome Complex. After narrowly escaping the destruction of the facility following a disaster in an unrelated area of the facility and the subsequent alien invasion and military cover-up, Walter has retired to a quiet life of studying botany in the Combine-controlled City 14.
