If you want to use your vehicles without waiting for them to reload (e.g., Firefighters extinguishing infinite fires, SWAT having infinite ammo), you can edit the game configuration files.
Warning: Back up your files before editing.

Emergency games pride themselves on realism. Unlike Command & Conquer, you don't build tanks—you dispatch ambulances, fire trucks, and police cars from real-world stations. The game enforces a hard unit cap (typically 60-80 active vehicles) to prevent memory overload and AI pathfinding collapses.
"Unlimited units" refers to bypassing this cap, allowing you to deploy 100, 200, or even 500 vehicles simultaneously.
If you are stuck in a campaign mission because the game won't let you buy more units, you have hit the Unit Cap. To have a "Full" powerful roster within the game rules, follow these tips: emergency 20 unlimited units full
1. Maximize Upgrade Points In Emergency 20, you must purchase upgrades to increase your unit cap.
2. Sell Unused Vehicles In the deployment phase, you might have old vehicles from previous missions that you don't need.
3. Use Multi-Purpose Units To feel like you have "more" units, use vehicles that can do multiple things:
For the true "Unlimited Units" experience that players often search for, we have to look at the modding community. Because Emergency 20 has a hardcoded engine limit on how many units can physically be on screen, removing the cap entirely can crash the game. However, modders have created Trainers and Mods that significantly raise this limit or remove the cost associated with units. If you want to use your vehicles without
The most popular way to achieve this is by using a Cheat Table (via Cheat Engine) or a generic PC Trainer.
What these tools usually offer:
Note: When using mods or trainers to spawn hundreds of units, be warned! The game engine is older. If you spawn 50 fire trucks at once, your frame rate will likely tank, and the pathfinding AI might have a meltdown. Use this power responsibly!
If you want to play "legit" but with fewer restrictions, Emergency 20 offers a built-in feature that acts as a middle ground. The Developer Mode allows for greater control over your budget and the ability to spawn units directly onto the map, bypassing some of the standard purchasing UI constraints. Look for a file named specification
While this doesn't technically give you "infinite" slots in the traditional UI, it allows you to spawn whatever you need, whenever you need it, provided you have the budget.
How to access it:
Once enabled, you will see new icons in your interface during freeplay modes. You can spawn vehicles and people instantly. This is great for players who want to simulate "unlimited" reinforcements during massive events without using third-party software.
When a major incident overwhelms normal capacity, clear goals and an organized surge plan matter most. “Emergency 20: Unlimited Units, Full” describes a scalable, decisive framework for activating unlimited operational units and delivering a full-spectrum response to catastrophic events—natural disasters, mass-casualty incidents, large industrial accidents, or cascading infrastructure failures. This article outlines purpose, command structure, activation triggers, logistics, communications, safety, legal/ethical considerations, and an implementation checklist.
Contrary to popular belief, there is no native cheat code for unlimited units in any official Emergency game. The developers (Sixteen Tons Entertainment) deliberately omitted it to maintain performance and challenge.
Therefore, achieving "unlimited units full" requires modification. There are three legitimate methods:
