While not playable characters, your support team via the Codec is an integral part of your 'build' and strategy. Dr. Madnar provides technical advice, Holly White offers intelligence, and Colonel Campbell gives mission directives. Regularly contacting them can provide crucial hints, item locations, enemy weaknesses, and even save your game. Think of them as your extended senses and knowledge base. Ignoring their advice can lead to unnecessary difficulties. For example, Holly might tell you about a specific guard's patrol pattern, or Madnar might explain how to disable a security system. Utilizing your support team effectively is a key component of a successful infiltration, making them an invaluable asset to Solid Snake's overall capabilities.
