Arma Reforger Game Master Reference

One-page cheat sheet for Arma Reforger's Game Master (GM) mode — Reforger's equivalent of Arma 3's Zeus. Covers the budget system, entity browser categories, camera controls, and the GME_AR enhanced editor mod.

The GM budget controls how many entities can exist in the world at once. Each scenario starts with a total pool of 100% (servers may cap this further). Placing entities draws from the pool; deleting them returns the budget.

Characters

~1–3% per soldier (infantry)
~1% per civilian

Vehicles

~5–10% wheeled vehicles
~10–15% tracked / aircraft

Structures & Props

<1% static props, signs
~1–2% fortifications

Monitoring

Current usage visible in the GM panel
Budget bar turns amber when low
Deleting entities immediately refunds budget

Tip: Remove dead soldiers and destroyed vehicles to keep your budget healthy. Bodies and wrecks still consume a small budget share until deleted.
