Key facts
SATURN script: the key facts
The basics
What is the SATURN script?
SATURN is a Cronus Zen script: a small program, saved as a .gpc file, that runs on the Cronus Zen itself. The Zen sits between your controller and your console or PC, so the script works the same way on every platform the Zen supports, with nothing installed on the console.
We built SATURN for Modern Warfare 4 first, then made sure the same file covers Warzone and Black Ops 7. SATURN V2 is the current version, updated for MW4’s full release. You’ll see it written as the SATURN script, the Saturn Cronus Zen script, the Saturn GPC script or the Saturn Zen script. They all mean the same file.
It’s our newest Call of Duty script and the one we keep most current with the MW4 patch cycle. If you mainly play older Call of Duty titles, our Call of Duty Cronus Zen scripts collection has the scripts built for those. Play more than Call of Duty? Our guide to the best Cronus Zen scripts for every game covers Fortnite, Rainbow Six Siege X, Apex Legends and more.
Compatibility
Which games does the SATURN script work on?
One SATURN file covers all three current Call of Duty games. Here’s how each one fits.
01 / MW4
Modern Warfare 4
SATURN’s home game. Built and tuned for MW4 first, with V2 made for the full release. MW4 has no PS4 or Xbox One version, so PS5 players connect the Zen through a Zen LINK.
Built for it02 / Warzone
Warzone
From Season 1 on 6 November 2026, Warzone runs on MW4’s weapons and progression, so the SATURN setup you use in MW4 carries straight over. Warzone leaves PS4 and Xbox One at the same time.
Same file03 / Black Ops 7
Black Ops 7
Covered by the same file, with its own weapons. Black Ops 7 is still on PS4 and Xbox One, so it’s the one SATURN game you can play on last-gen consoles.
Same fileHere’s where you can run SATURN for each game, all through the Cronus Zen.

Warzone Season 1
SATURN script for Warzone Season 1
From midnight ET on 6 November 2026 (5am UK time), Warzone Season 1 fully integrates Modern Warfare 4. All 33 MW4 launch weapons come over with their Apex Attachments, Hajin is the new battle royale map, Zodiac is the new Resurgence map, and Verdansk and Rebirth Island return later in the season.
Because Warzone now uses MW4’s guns, the SATURN values you’ve tuned in MW4 are your starting point. Fights are longer and further away than in multiplayer, though, so a few settings are worth changing.
Start from your MW4 values
Your MW4 guns are the same guns in Warzone, so begin with the values you tuned in MW4’s Firing Range.
Make the long-range changes
Switch to Ellipse, drop Aim Radius a step and raise the end-of-spray value on your main assault rifle.
Test at Warzone ranges
Fire full sprays at 40 to 60 metres in your first few matches and change one value at a time.
Save and play
The mod menu saves on the Zen, so your Warzone setup is there next time you turn it on.
Tip
Play MW4 multiplayer and Warzone? Write both sets of values down. Swapping shape, Aim Radius and the end-of-spray value in the mod menu takes a few seconds when you change modes.

Getting ready for Season 1?
SATURN is one download for Warzone, MW4 and Black Ops 7, with the PDF setup guide in the same email.
Modern Warfare 4
SATURN script for MW4
MW4 is where SATURN started, and it’s where most of our guides live. If MW4 multiplayer is your main game, start here:
Download, Zen Studio, memory slots and Program Device, step by step.
The in-game controller values to pair with SATURN, plus a tuning routine for each gun.
What each SATURN mod does in MW4 and which ones to turn on first.
MW4 is PS5-only on PlayStation, so this is the setup PS5 players need.
The starting points we use in MW4: the Circle shape, a low Aim Radius (about a quarter of the slider), a middle Aim Speed and per-weapon anti-recoil that starts low. Your PDF has per-weapon numbers for the main MW4 guns, and assault rifles like the HAN 86, M4 and Kastov 762 are the ones to set up first.
Black Ops 7
SATURN script for Black Ops 7
SATURN covers Black Ops 7 in the same file, with Rapid Fire tuned for it too. The one rule: Black Ops 7 has its own weapons, so give those guns their own anti-recoil profiles instead of reusing your MW4 values. Start low and build up in the Firing Range, the same way you would in MW4.
Black Ops 7 is also the only SATURN game still on PS4 and Xbox One. The Cronus Zen works on both, so on a last-gen console, Black Ops 7 is where you’ll run SATURN. See every option in our Black Ops 7 Cronus Zen scripts collection.
The toolkit
Every SATURN mod at a glance
SATURN has 20+ mods. These are the groups they fall into and what each one does.
01 / Aim
Solar Aim Assist
Six aim shapes (Circle, Ellipse, Oval, Lemniscate, Orbit and Rose) with adjustable Aim Radius, Aim Speed, Boost Radius and Boost Speed. It works with the game’s own aim assist, so keep Target Aim Assist On.
02 / Aim
Hip Assist and Strafe Assist
Hip Assist keeps the help going when you fire from the hip. Strafe Assist helps when a target cuts across your screen.
03 / Recoil
Anti-Recoil System
Vertical and horizontal control with separate start, mid and end values, plus Kick Vertical and Kick Time for the first-shot kick. Every weapon gets its own profile.
04 / Fire
Rapid Fire
Turns semi-auto weapons into full-auto fire at an adjustable rate. Leave it off on guns that are already full-auto.
05 / Shooting
Jump Shot and Drop Shot
Jump Shot jumps for you as you fire. Drop Shot and Easy Drop Shot drop you prone as you open fire.
06 / Movement
Movement mods
Slide, Slide Cancel, Bunny Hop, Dive Cancel, Snake, Tap To Slide and Tap To Dive, run in Slide Only, Dive Only or Hybrid mode.
07 / Menu
On-Zen mod menu
Every setting lives on the Zen’s own screen. Change a value mid-session without a PC, and it’s saved on the device.
08 / Support
PDF, updates and Discord
A PDF setup guide with starting values, updates for the life of the script, and private ticket support in our Discord.

How to set up the SATURN script on your Cronus Zen
You need a Windows 10 or 11 PC to load SATURN onto the Zen. After that, you play without it.
Get SATURN from gpcscripts.com
Check out on the SATURN product page. The download link shows on your order confirmation page and arrives by email with the PDF setup guide.
Update the Zen and Zen Studio
Use firmware 2.2.14 or newer and Zen Studio 1.6.1 Build 82 or newer.
Program SATURN to a memory slot
Connect the Zen’s PROG port to your PC with a data cable, drag SATURN into a slot and click Program Device. Build and Run only loads it until the Zen restarts.
Check Tournament Mode is off
Tournament Mode switches scripts off. If SATURN loads but nothing happens, check this first.
Connect and launch your game
Plug the Zen’s CONSOLE/PC port into your console or PC and your controller into the Zen. On PS5, add a Zen LINK.
Enter your starting values
Open the SATURN mod menu on the Zen, enter the PDF values for your main gun and tune one value at a time.

Common questions
SATURN script FAQ
Q.What is the SATURN script?
SATURN is a Cronus Zen GPC script made by GPC Scripts for Modern Warfare 4, Warzone and Black Ops 7. It has 20+ mods, including Solar Aim Assist with six aim shapes, per-weapon anti-recoil, Rapid Fire, Jump Shot and movement mods, all controlled from a mod menu on the Zen.
Q.Does the SATURN script work on Warzone Season 1?
Yes. Warzone moves onto MW4’s weapons and progression with Season 1 on 6 November 2026, and SATURN covers Warzone in the same file. For Warzone’s longer fights, use the Ellipse shape, a slightly smaller Aim Radius and more end-of-spray anti-recoil.
Q.Does SATURN work on Black Ops 7?
Yes. The same SATURN file covers Black Ops 7. Give Black Ops 7 weapons their own anti-recoil profiles rather than reusing your MW4 values.
Q.Which consoles does the SATURN script work on?
SATURN runs on PS5, Xbox Series X|S and PC through the Cronus Zen. Black Ops 7 also runs on PS4 and Xbox One. On PS5, use a Zen LINK, which MW4 needs because it has no PS4 version.
Q.Are the Saturn GPC script and the Saturn Zen script the same thing?
Yes. GPC is the scripting language the Cronus Zen runs, so the SATURN script, the Saturn GPC script, the Saturn Zen script and the Saturn Cronus Zen script all mean the same file.
Q.Do I need a Cronus Zen to use SATURN?
Yes. SATURN runs on the Cronus Zen, which isn’t included. You also need a Windows PC to load the script onto the Zen, but not while you play.
Q.What is the latest version of SATURN?
SATURN V2 is the current version, updated for MW4’s full release. Updates are included for the life of the script, and when Call of Duty patches we test SATURN and release a new version if it’s needed.
Q.SATURN is loaded but nothing happens. What should I check?
Make sure Tournament Mode is off and that SATURN was programmed to a memory slot with Program Device, not loaded with Build and Run. Still stuck? Open a ticket in the GPC Scripts Discord with your order number.
Q.Where can I download the SATURN script?
From gpcscripts.com. The download link appears on your order confirmation page straight after checkout and is emailed to you with the PDF setup guide.
