Resident Evil 5 dramatically shifted the classic survival horror franchise toward high-octane action, making resource management a unique challenge during intense cooperative battles. While ammunition scarcity adds tension to your first playthrough, unlocking the ability to fire without limits transforms the gameplay experience entirely. This guide details the exact steps required to unlock this powerful feature and dominate the bio-organic threats.

Fully Upgrading Your Chosen Weapon

The first prerequisite to achieving limitless fire is maximizing the statistics of a specific firearm within your inventory. You must upgrade every single attribute, including firepower, reload speed, capacity, and critical hit rate, to their absolute limits. This process requires a significant financial investment, meaning you will need to farm valuable treasures and gold across various campaign chapters.

Once a weapon is completely maxed out, the game internally flags it as eligible for special modifications. It is worth noting that some weapons unlock unique secondary firearms in the shop when fully upgraded. For instance, maximizing the starting handgun gives you the option to purchase the powerful M93R burst pistol.

Purchasing the Infinite Ammo Feature

After upgrading your firearm, you must exit the main campaign mode and navigate to the Bonus Features menu from the title screen. Here, you will find the option to unlock the limitless modification using Exchange Points accumulated by completing chapters and earning high mission ranks. The cost of the unlock varies depending on the overall power and tier of the specific weapon category.

If you need to accumulate these points quickly, completing shorter boss fight chapters or playing the Mercenaries mode are highly effective strategies. You can check your progress and current totals within the main menu interface before launching your next session.

Activating Infinite Ammo in the System Settings

Simply buying the unlock from the bonus menu does not automatically apply the effect to your active gameplay session. Before starting a game, you must explicitly toggle the infinite ammo setting to allowed within the initial network and game setup configuration screen. If this option remains disabled, your weapons will continue to consume normal inventory cartridges during combat.

This menu system allows hosts to customize the experience, ensuring that purists can still enjoy standard survival mechanics if they choose. Players looking to optimize their setups can find additional gameplay insights through community platforms like YouTube to enhance their farming strategies. Once enabled correctly, you can freely distribute these weapons to either Chris or Sheva.

Managing Inventory and AI Partner Behavior

Equipping your computer-controlled companion with a limitless weapon is one of the most effective tactics for tackling higher difficulty settings. The AI partner features exceptional aiming precision but normally struggles with conservative ammunition management during crowded encounters. By removing the restriction on their supply, Sheva becomes an incredibly reliable frontline defender.

With the threat of running out of rounds eliminated, you can clear out duplicate boxes from your inventory slots to make room for healing items and heavy body armor. This strategy proves essential when attempting Professional mode, where enemy attacks can easily defeat your characters in a single hit.
