The Destruction of Rhoemer's Base was a major conflict of Syphon Filter in which Gabe Logan sabotaged operations on a compound owned by Black Baton. The entire area was decimated by explosives which Logan planted.
Despite Gabe's success, Lian Xing was captured and 'killed' by Rhoemer; it later transpired she was alive but infected with the virus. Black Baton suffered significant losses, including the death of Gabrek and the destruction of an attack helicopter.
