Behind the scenes

In Metal Gear Solid: Portable Ops Plus, the gun cameras are no longer present in the Silo Complex portion of the level, and instead are utilized along with Claymore mines in random levels that require you to get to the access point under a time limit to compensate for the lack of enemy soldiers.

If the player looks closely at the gun cameras in Metal Gear Solid 2: Sons of Liberty, they'll notice that the magazine resembles that of the Patriot.


Gun camera sensors can be temporarily disabled with chaff grenades.They can be destroyed with Stinger missiles, C4, or any handheld gun.

After retrieving the [GUN-CAM DEFENDER] blueprint in Metal Gear Solid V: The Phantom Pain, side-op 9, the blueprint document in the iDroid database reads "Document required to develop [INTERCEPT HEAD] (D-Walker armament) and [GUN-CAM DEFENDER] (security device)." Although D-Walker can be developed, deployed and used with the intercept head, the security device can not be developed to be used on Mother Base/FOB(s) for reasons yet to be determined. It will be included in the November Update, and will cost 350,000 GMP to develop.
