Black Chamber was a special forces group founded after the Outer Heaven Uprising to act as a sort of "shadow FOXHOUND." After Solid Snake's success with Operation Intrude N313, FOXHOUND became too well known to the general populace and was therefore under closer surveillance by rival intelligence bodies. Black Chamber was founded to perform operations that FOXHOUND would do normally, but they weren't under surveillance like FOXHOUND was at the time. Several of their activities that they performed included assassinations of anti-American foreign leaders, removal of domestic civilians engaged in anti-establishment activities, interfering in various civil wars and strifes for America's behalf, and other black operations.
