Rather impressive for 1998 that the guards have compound viewcones meant to simulate peripheral vision and also to emulate ambushes. Their vision factors in darkness, distance, geometry proximity, movement speed and equipped target armament, and that vision is augmented based on whether they're unaware, suspicious or alerted. When previously highly alerted, the vision cones expand, including the rear one, allowing them to pretend to not notice you sneaking up on them so they can ambush you. Their hearing is based on distance and sound propagation nodes and augmented by their alertness state, and the sounds they can hear are based on the material that is emitting the sound. If only other games took this approach as the base level standard all those years ago.
