WWZ Aftermath Co-op Trainer

I’m looking for a clean, standalone trainer that plugs straight into World War Z: Aftermath and works flawlessly in the cooperative modes—both online co-op sessions and offline play—but never touches the public multiplayer/PvP environment. The build must target the latest Steam/Epic release only; I don’t need backward-compatibility.

Core functions I expect at the press of a hotkey:
• Unlimited health
• Unlimited ammo with instant reload
• Infinite sprint
• Unlimited equipment / inventory items
• Infinite melee stamina

The trainer can be external or internal; stability and low detection risk are what matter. Please keep the UI minimal, let me re-map hotkeys easily, and make sure every feature can be toggled on-the-fly without crashing the game or desyncing co-op partners.

Deliverable: a compiled, virus-free executable plus the source (so I can rebuild after future patches) and a quick read-me covering setup, hotkeys, and any dependencies. If an update breaks functionality within two weeks of delivery, I’ll need a quick fix included.
