When everyone at Capital Media started playing Half-Life, I decided to figure out how to build a custom map or our exact building. There was a lot of tension and tight deadlines, so being able to kill each other inside of an artificial environment was much cleaner than disgruntled employees bringing machine guns to work. It helped to have everyone's face skinned to their player also...wheres the boss?!
The Greenscreen area was always a great place to hide in the shadows.
All of the employees at capital media were skinned for the game.
