Still copying scriptsmade for someone else?

You find a script on Reddit or Discord. It almost works.
Then you try to make it yours.

The recoil values are wrong for your weapons.

The script was tuned for someone else’s loadout, sensitivity and playstyle.

The controls don’t match your setup.

Changing one button means searching through unfamiliar GPC code.

The mods you need live in different scripts.

Combining Anti-Recoil, Rapid Fire and movement mods means merging code and fixing conflicts.

One small change can break the entire script.

Zen Studio Live shows a compiler error, but you don’t know which line caused it.

You shouldn’t need to become a programmer just to change your Cronus Zen setup.

Build it visually. Manage theentire script in one place.

Your weapons, mods, controls and generated GPC stay together as one editable setup.

Tune each weapon and mod visually

Set separate Anti-Recoil values for your weapons. Add Aim Assist, Rapid Fire and movement mods to the same script without merging GPC code. Adjust buttons and timings visually.

Keep every script and setting together

Open a saved script and change its weapons, mods or controls in Tunez. When you are ready to test, send it to your Zen with Tunez Companion.

Start faster with a Loadout

Start with a ready-made game Loadout when one is available, then change its weapons, mods and controls for your setup. Or build the complete script from scratch.

Cronus Zen mods, weapon profiles and tuning tools

Tunez covers the script itself, the controls around it and the tools you need to get useful starting values.

Anti-Recoil, Aim Assist and Rapid Fire

Tune separate values for each weapon profile instead of accepting settings made for a different loadout.

Weapon Profiles and Weapon Sync

Choose weapons from a game library, fill both profiles, and keep the right combat settings active as your weapon state changes.

Firing, movement and utility mods

Add Auto Reload, Scope Assist, Crouch Shot, Jump Shot, Strafe Shot, Slide Cancel, Bunny Hop, Lobby Keepalive and more.

Controls and button mapping

Match the script to your controller layout and set the activation buttons for each mod.

Build your own custom mods

If the mod you need is not in the library, create it with your own triggers, settings and behavior, then add it to your script.

Aim Assist Calculator

Enter your in-game sensitivity, deadzones, FOV and playstyle to get a practical set of starting values you can refine.

Why build your own setup?

A downloaded script gives you someone else’s decisions. Tunez gives you a setup you can understand and change.

Someone else’s script

  • Recoil was tuned for someone else’s weapons.
  • Controls may not match your setup.
  • Adding another mod means editing or merging code.
  • When the game changes, you have to find or edit another GPC file.

Your script in Tunez

  • Choose your weapons and configure both profiles.
  • Set mods, buttons and timings visually.
  • Keep the full setup with the saved script.
  • When a game update changes your setup, adjust the values in Tunez.
