Indirect Kill

In the Metal Gear series, Indirect Kill refers to the player neutralizing an opponent by killing them, without recieving credit for the kill. This can be used to obtain code names (such as 'FOXHOUND' in Metal Gear Solid V: The Phantom Pain), achievements and trophies (such as 'Peace Walker' from Metal Gear Solid 3: Snake Eater HD Edition), or special items (such as the bandana in Metal Gear Solid 4: Guns of the Patriots) that require limited or no kills or to prevent accumulation of Demon Points in Metal Gear Solid V: The Phantom Pain.
