Resident Evil 5 on PlayStation 4 brings back the intense cooperative survival action of Capcom's classic title with enhanced visual clarity and smoother frame rates. While traditional button-input cheat codes are absent, the game features a rewarding progression system packed with powerful unlockables, infinite ammunition options, and alternative costumes. Understanding how to earn these gameplay bonuses allows players to dominate higher difficulty levels and experience the campaign with exciting new advantages.

Unlocking Infinite Ammo for Weapons

Acquiring infinite ammunition transforms the survival horror experience into an explosive action playground. To unlock infinite ammo for any specific firearm, you must fully upgrade all of its individual attributes in the inventory shop. Once fully upgraded, the infinite ammo option becomes available for purchase in the Extra Features menu using Exchange Points earned throughout the campaign.

After purchasing the feature in Extra Features, you must ensure that infinite ammo is toggled on in the game settings before starting a chapter. This bonus applies to iconic weapons such as the S&W M500 magnum, the Rocket Launcher, and various shotguns. Having unlimited firepower makes tackling Veteran and Professional difficulties far more manageable for you and your partner.

Special Weapons and Secret Arsenal Unlocks

Beyond upgrading standard firearms, Resident Evil 5 rewards dedicated players with special endgame weaponry. Fully upgrading the initial handguns and shotguns unlocks legendary gear like the Gatling Gun for Chris and the Longbow for Sheva. These unique weapons offer massive destructive potential and do not require traditional reloading mechanics during combat encounters.

The devastating Infinite Rocket Launcher can also be unlocked through direct campaign performance rather than standard upgrades. Players must complete the entire main story on any difficulty setting in under five total hours. Achieving this speedrun milestone automatically grants infinite rockets, allowing you to breeze through subsequent playthroughs effortless.

Bonus Costumes and Character Filters

Visual customization plays a significant role in rewarding players who explore every corner of Kijuju. Completing story chapters and shooting hidden BSAA emblems scattered throughout the environment unlocks alternative outfits for Chris Redfield and Sheva Alomar. These cosmetics range from tactical gear to unique themed costumes that add personality to cutscenes and gameplay.

In addition to costumes, players can spend Exchange Points to unlock visual graphic filters that alter the game's atmosphere. Options like Classic Horror, Sepia, and Noise filters change the color palette to recreate retro cinematic styles. Combining custom outfits with atmospheric visual filters offers a fresh aesthetic experience during repeat campaign runs.

The Mercenaries United and Bonus Modes

The PlayStation 4 edition of Resident Evil 5 includes The Mercenaries United, combining all previously released Mercenaries content into one comprehensive mode. Players can choose from an expansive roster of characters and alternate costumes right from the beginning. High scores earned in this fast-paced arcade mode yield substantial Exchange Points that carry over into the main campaign.

Playing bonus modes is one of the fastest methods for accumulating currency to buy high-tier unlockables. Mastering enemy spawn patterns and maintaining high kill combos ensures a steady flow of points for unlocking figurine models, extra weapons, and special features. Engaging with these extra modes completes the ultimate Resident Evil 5 toolkit for completionists.
