Call of Duty 4: Modern Warfare & Modern Warfare Remastered
Dead Silence reduces a player's footstep noise significantly, allowing players to walk, sprint, and jump 60% silently. This perk is mainly used by players wishing to be stealthy; it lowers footstep sound so that it is 60% silent - however it can still be heard, usually only picked up by high quality sound systems. It allows players to clearly hear other players' footsteps who are not using the perk. However, crouch-walking, going prone, or moving while aiming down sight completely cancels noise created by movement. Dead Silence does not have an effect on weapon switching sounds, however. Even with the perk, falling from any height makes at least a slightly audible sound, and especially so from large heights where the loud cracking noise is still made. Rustling through bushes/grass also still creates noise.
Dead Silence is identical to its Call of Duty 4: Modern Warfare counterpart; however, due to the ability to adjust sound settings and thus remove ambient noises and announcer voices, this perk can prove more useful than what it did in the previous installment.
Call of Duty: Modern Warfare 3
Dead Silence appears again in Call of Duty: Modern Warfare 3. It silences the player's footsteps and reduces the effect of the Recon perk, from 12 seconds to six seconds. To unlock Dead Silence Pro, the player needs to earn 50 close range kills, similar to Ninja and Scrambler fromCall of Duty: Modern Warfare 2. Dead Silence can be canceled out by Sitrep Pro within close proximity. Dead Silence Pro negates falling damage, similar to Commando Pro from Call of Duty: Modern Warfare 2 and Lightweight Pro from Call of Duty: Black Ops. This does not give the player the ability to survive kill zones disguised as long drops, including the well in Seatown and falling off Overwatch.

Dead Silence returns in Call of Duty: Strike Team. It allows players to reduce their audio signature. The Pro version allows the player to greatly reduce their audio signature. It is unlocked after completing the Europa Fall mission.
Call of Duty: Ghosts
Dead Silence returns in Call of Duty: Ghosts as a stealth perk. It quiets the users' footsteps (to where it is barely audible; it seems to decrease movement noise by 90%). This effects on enemies could be countered by Amplify, but not entirely (Dead Silence users' footsteps heard by Amplify are slightly less audible than regular footsteps heard without Amplify, but still distinguishable. One note is that it decreases the volume of footsteps, not the range which they can be heard.
"Move quietly and resist detection from acoustic sensor" -In game description
Call of Duty: Mobile
"Grants silent movement while walking, crouching or during prone."
Dead Silence returns in Call of Duty: Mobile as a Tier 3 perk. It used to make your movement silent, but it later got nerfed in Season 13, where your movement is only silent when your walking, crouching or in a prone position.
Call of Duty: Modern Warfare (2019)
"Temporarily makes your footsteps quieter. Kills refresh duration."
— In-game description
Dead Silence returns in Call of Duty: Modern Warfare as a Field Upgrade rather than a perk. It entirely silences one's footsteps, but for a limited duration which are refreshed in each kill, akin to the Exo Mute Device in Advanced Warfare. While under the effects of Dead Silence, the player will also move faster than normal. Dead Silence is unlocked at level 10.
Melee kills count towards Dead Silence Pro.
Dead Silence was originally going to be an ability of one of the four planned multiplayer character abilities. However, the character models were scrapped and it was added as the Pro ability of Ninja.
Dead Silence Pro doesn't completely negate falling damage. A player can still die if playing on hardcore and by jumping from a great height several times.
In Modern Warfare 3, the Pro version of Sitrep did not counteract Dead Silence until an update.
