What is SATURN?
SATURN is a Cronus Zen script made by GPC Scripts for Modern Warfare 4, Warzone and Black Ops 7. It packs 20+ mods into one file: Solar Aim Assist with six aim shapes, per-weapon anti-recoil with start, mid and end values, Rapid Fire, Jump Shot and a full set of movement mods. Everything is controlled from a mod menu on the Zen that saves your settings, and it runs on PS5, Xbox Series X|S and PC.
Key facts
SATURN at a glance
Aim
Solar Aim Assist, Hip Assist and Strafe Assist
Solar Aim Assist is SATURN’s main aim mod. It works together with MW4’s own aim assist, so Target Aim Assist needs to be On in the game’s controller settings. You choose a shape, then tune four values: Aim Radius, Aim Speed, Boost Radius and Boost Speed.
Hip Assist
Keeps the assist working when you’re firing from the hip, for fights too close to aim in.
Strafe Assist
Helps when a target cuts across your screen side to side.
Starting point
Circle shape, a low Aim Radius (about a quarter of the slider) and a middle Aim Speed. Raise the radius one step at a time. Full values are in our MW4 Cronus Zen settings guide.
Recoil
Per-weapon anti-recoil
Every MW4 gun climbs differently, and the climb changes through the spray. SATURN’s anti-recoil handles that with separate start, mid and end values for vertical and horizontal recoil, plus Kick Vertical and Kick Time for the first-shot kick. Each weapon gets its own profile, so your SMG and your LMG never share a setting.
The setup PDF has starting values for the main MW4 weapons. Assault rifles like the HAN 86, M4, Kastov 762 and Patriot XMR gain the most, because you fire long mid-range bursts with them. Re-check a gun’s values after you equip its Apex Attachment, because it can change how the weapon handles.
Fire control
Rapid Fire
Rapid Fire turns semi-auto weapons into full-auto fire: hold the trigger and SATURN fires at the gun’s fastest rate. It’s tuned for MW4, Warzone and Black Ops 7. Leave it off on guns that are already full-auto.
Movement
Movement mods
SATURN’s movement mods are timed for MW4’s movement, and you pick one movement mode to run them in: Slide Only, Dive Only or Hybrid.
Settings
The on-Zen mod menu
Every SATURN setting lives in a mod menu on the Cronus Zen’s own screen. Change a value mid-session without a PC, and it’s saved on the Zen the first time you set it, so you never redo your setup.
Starter setups
Which SATURN mods to turn on first in MW4
Don’t switch everything on at once. Start with the setup that matches how you play, then add mods one at a time.
One file, three games
SATURN on Warzone and Black Ops 7
One SATURN file runs MW4, Warzone and Black Ops 7. MW4 Season 1 is reported for 6 November 2026, with the Warzone integration expected around then, so the script you set up for MW4 carries straight over. Warzone fights happen at longer range, so expect to raise the end-of-spray anti-recoil on your main AR and lower Aim Radius a step. SATURN includes free updates, and new seasons are covered as they release. For the Warzone Season 1 settings and a game-by-game setup, see our SATURN script guide for Warzone, MW4 and BO7.
PS5, Xbox and PC
Platforms and setup
SATURN runs on PS5, Xbox Series X|S and PC through the Cronus Zen. MW4 is the first Call of Duty without a PS4 version, so on PS5 the Zen connects through Cronus’s Zen LINK module. Our Cronus Zen PS5 setup guide for MW4 covers it step by step. On Xbox and PC, load SATURN into a memory slot with Zen Studio, plug the Zen in and play.
