Lufwa Valley

Lufwa Valley was a valley in the Angola-Zair border region. The valley was used by Cipher as a site for development and possible testing of the vocal cord parasites. The valley was always covered in a heavy mist. Deep inside the valley Code Talker was held in a mansion heavily guarded by Zero Risk Security soldiers. Code Talker was developing vocal cord parasites and producing samples for use in The Devil's House.

Venom Snake infiltrated the valley in 1984 and encountered the squad of sniper Skulls. After either defeating or avoiding them, Snake got inside the mansion and extracted Code Talker.

Later, Venom Snake came back to the valley to recover Code Talker's research material.
