Reaper patch notes and update history (Modern Warfare 4)

Every public Reaper build for Modern Warfare 4, newest first, with the notes that shipped with it. Updates are free and install from the browser in about a minute. This page is generated from the same release registry the installer uses, so it is always current.

Reaper V1.5.2 (2026-09-30)

Reaper V1.5.2: the menu now opens instantly with View + Menu. Settings carry over.

• The menu now opens instantly: press View + Menu (Create + Options) together, the same as Fadeaway.
• Everything else plays the same. Your settings carry over. Re-flash to update.

Reaper V1.5.1 (2026-09-29)

Reaper V1.5.1 fixes the Anti Drift page changing your anti-recoil. Everything else is the same as 1.5.

• Fixed: on the Anti Drift page, pressing Up or Down on Calibration, Drift Test, Drift Reset or Drift Values turned your anti-recoil Off, or set Primary strength to 0, and saved it.
• Now only the Anti Drift On/Off row changes with Up or Down. If your anti-recoil switched itself off before, set it again once.
• Everything else is the same as 1.5.

Reaper V1.5 (2026-09-29)

Reaper V1.5 brings the new Vera look: the VERA logo spin when it starts, a clean idle screen and the same menu layout as Fadeaway. Gameplay and your settings are the same as 1.4.

• New Vera look: the VERA logo spins when the script starts, the same as Fadeaway.
• Clean idle screen: VERA, REAPER and the version, with the menu buttons at the bottom.
• Menus use the same layout as Fadeaway: the page name, the setting and its value in the middle, and a page counter.
• Menu text is now in capitals, and the menu gives a short buzz when you open it, close it or change a value.
• Gameplay and your settings are exactly the same as 1.4.

Reaper V1.4 (2026-09-29)

Reaper V1.4 fixes the aim going left and right while shooting, makes Automatic anti-recoil use the gun you pick, stops recoil pulling after the gun stops firing, and fixes saved bindings, Shot Mod and quick toggles. Same menu as V1.3.

• Fixed the aim going left and right while shooting: Boost and Strafe Assist no longer switch on and off between shots, and PS5 aim assist no longer cuts out while firing.
• PS5 consoles running the fast 2 ms Zen speed no longer turn the aim assist circle into a side-to-side shake.
• Automatic anti-recoil now uses the gun you pick in the menu (ISO Nightshade or Han 86) instead of always pulling like the ISO Nightshade, and the Anti Recoil page shows the Weapon field in Automatic.
• With game vibration on, recoil stops pulling once the gun stops firing (empty magazine, reload). Auto Rapid Fire no longer pulses the full-auto ISO Nightshade and Han 86.
• Touchpad and Share button bindings are kept after a restart, and a damaged or foreign save loads clean defaults. Your 1.3 settings load unchanged.
• Shot Mod can no longer keep firing on its own, Rapid Fire keeps working without game vibration, and quick toggles turn on to your last value.
• Faster and lighter: quick toggles save when you stop fighting, the screen no longer redraws on every trigger pull, and the build is 30% smaller.

Reaper 1.3 (2026-08-31)

Reaper 1.3 closes the rapid-fire teardown gaps so no extra shot fires after disable, stops Automatic Rapid Fire self-engaging on anti-recoil-Off profiles, makes quick toggles save without the full apply pass, clears Vehicle Mode state on every exit, and stops the quick editor opening during the menu chord.

• Every rapid-fire disable path now stops the firing combo and clears the latched rate, so no extra shot fires after disable and a new weapon can never inherit the old weapon's rate.
• Automatic Rapid Fire can no longer switch itself on for a profile whose anti-recoil mode is Off.
• Gameplay quick toggles now save your settings without re-running the full apply pass, so the recoil curve and controller remapping are untouched mid-fight.
• Vehicle Mode clears all held script outputs on both of its exit paths.
• The weapon quick editor can no longer open while the Menu button is held, so the menu chord always opens the full menu.
• The Zen idle screen now shows GAME VIBRATION OFF whenever Weapon or Automatic recoil fires with game vibration off, so the hidden vibration requirement is finally visible.

Reaper 1.0 (2026-08-22)

Reaper 1.0 for Modern Warfare 4 with ISO Nightshade and Han 86 profiles, clean Zen headers, and a dedicated public install channel.

• Public MW4 launch build with a dedicated Reaper install channel.
• Weapon mode includes ISO Nightshade and Han 86 named profiles.
• ISO Nightshade has a verified owner-only three-stage recoil curve.
• Han 86 has a verified owner-only three-stage recoil curve.
• Removed the V7 and P1/P2/P3 corner labels from every Zen menu page.
• Automatic applies the ISO Nightshade profile as a fixed fallback and does not detect the equipped weapon; Han 86 is selected manually in Weapon mode.
• Includes the REAPER boot identity and humanization layer.

How to update

Plug the Zen into a PC with the USB cable, open the Reaper page, and install the current build from the browser. Nothing is downloaded to the PC and your saved profiles carry over between builds. If the device is not detected, the setup guides cover cables, ports and firmware. Help is in the Discord.

How this page is built

Every entry above comes from the release registry that the installer itself reads, so a build appears here the moment it is available to install and never before. Dates are the day the build went live. Version numbers match the label the Zen shows after an install. When Modern Warfare 4 patches, the next build lands here with its notes on the same day it ships, which is the fastest way to confirm that Reaper has been rebuilt for the current patch.
