Overview
Grave House is a Cronus Zen script for Call of Duty, programmed straight to a slot from the browser.
Grave House runs on the Cronus Zen rather than on the console, so the same file works on PS5, PS4, Xbox Series, Xbox One and PC: the Zen sits between your controller and the machine and handles the pairing. It is published by Noozbar.
There is nothing to install. Connect the Zen to this site, pick a slot, and Grave House is written to the device, then you load into Call of Duty and open the script menu on your controller to check it is running. It is free: program it from this page, or take the .gpc from its post in the Cronus Zens Discord.
Call of Duty scripts are aim and recoil work: steadying the stick while you are firing, and handling the jump and slide inputs that are awkward on a controller. They are written against the current Black Ops title and a weapon tuning update can change how a recoil pattern feels overnight.
