AI Techniques

• I built an audio/visual event manager into the
  Unreal engine so NPCs could detect things like
  footsteps, gunshots, smashed windows, objects
  hitting the ground, drawn weapons, screams,
  distress, etc. -- and more importantly, it could
  distingish between them. I also wrote behaviors
  for the NPCs so they could react appropriately to
  these events.
