In Metal Gear Solid (1998) and its associated demos, the CHAFF.G (Chaff Grenade) is a throwable weapon that releases metallic cloud particles upon detonation. This effect temporarily jams electronic security systems, security cameras, and the player's own Soliton Radar. It is an essential stealth tool used by Solid Snake to bypass electronic surveillance undetected.
Introduced during the infiltration of Shadow Moses Island in
Metal Gear Solid (1998), this tactical item is distributed across key areas such as the Heliport and Tank Hangar. Its inclusion in early promotional and trial releases, including the
Metal Gear Solid SharkByte Memory Card (1998) interactive media, the
Metal Gear Solid: VR Missions Demo CD (1999), and the
Metal Gear Solid Demo CD (2002), allowed players to experiment with non-lethal evasion tactics prior to or alongside the main game's release. In these demo formats, the item served as a crucial teaching tool for navigating complex patrol grids under strict time constraints.
Within the broader
Metal Gear Solid franchise, this specific iteration of the chaff grenade set a precedent for electronic warfare mechanics in stealth games. It forced players to balance the tactical advantage of disabling enemy sensors against the disadvantage of losing their own navigation interface. This risk-reward dynamic became a signature element of the series' level design, influencing how future entries handled electronic countermeasures and player-versus-environment interactions.
