Comprehensive Sandbox Control

Comprehensive Sandbox Control is an all-in-one cheat and sandbox toolkit for Hearts of Iron IV. It combines persistent buffs, repeatable cheat decisions, and contextual state and country controls in one clean package.

CSC was made because, after years of game updates, Cheat Mods Combined had become broken at its core. CSC is a clean, modern reimplementation of that general idea: one convenient sandbox mod, rebuilt around current HOI4 systems rather than patched on top of aging foundations.

Persistent Buffs

• 12 independent buff families
• Politics, diplomacy, research, construction, production, manpower, army, navy, air, training, special forces, and intelligence
• Five settings for each family: Off, Low, Medium, High, and Extreme
• Mix and match any number of buffs

Repeatable Cheat Decisions

• Political power, command power, manpower, fuel, stability, and war support
• Army, navy, and air experience
• Equipment and convoy stockpiles
• Research discounts and additional research slots
• Government and ruling-party controls
• World tension adjustments
• Offsite civilian factories, military factories, and dockyards
• Commander and admiral trait packages
• Resources, infrastructure, and building slots for core states
• Strategic resources for your capital

State Sandbox Tools

• Transfer state ownership or control
• Add or remove cores and claims
• Move your capital
• Add building slots and repair buildings
• Take or remove resource rights
• Add or remove individual strategic resources
• Mark and transfer multiple states at once

Country Sandbox Tools

• Annex or puppet countries
• Release subjects or grant independence
• Adjust autonomy
• Force white peace
• Invite, remove, leave, create, or dismantle factions
• Change faction leaders

Buffs
Open your country’s Politics screen and find the CSC buff slots. Choose Off, Low, Medium, High, or Extreme for each buff family.

Cheat Decisions
Open the Decisions screen and select Show Cheat Decisions. This reveals the organized CSC decision categories. Select Hide Cheat Decisions when you want to collapse them again.

If the list does not immediately refresh while paused, briefly unpause the game.

State Controls
Select a state and use the CSC button attached to the State interface.

Country Controls
Select another country through Diplomacy and use the CSC button in the selected-country interface.

Actions with major consequences include confirmation prompts to help prevent accidental map destruction.

• Works with vanilla Hearts of Iron IV
• Works with or without DLC
• No hard DLC dependencies
• Designed to coexist with additive mods and vanilla-style overhauls
• Tested with Road to 56

Compatibility for total conversions, like Old World Blues and Millennium Dawn, is planned for future updates.

Some total conversions may work partially, but may damage your save.

CSC changes the game checksum and disables achievements. Single-player is the supported experience; Co-op support is currently experimental.

CSC is a clean implementation and does not directly redistribute code or assets from the mods below, but their ideas and approaches were invaluable references.

• Vincente Steele — Cheat Mods Combined
• The original creators of EasyBuff+, Cheat Mod, Population Cheat, Easy Cheats, and National Cheats—the mods brought together by Cheat Mods Combined
• < A r x y > — State Interactions (In One)

Thank you to everyone who created, combined, maintained, and learned from these tools over the years.

Anyone is free to modify CSC, build compatibility patches, or include its work in another mod.

All I ask is that Comprehensive Sandbox Control and myself are credited, and that the credit remains visible wherever the reused work is published.

Feedback, bug reports, and compatibility reports are welcome.
