Resident Evil 4 Remake starts protagonist Leon S. Kennedy off with a handgun, knife, First-Aid Spray, bullets and a dream. It’s not long before he finds other tools to even the odds against the enemy, whether it’s new guns or upgrades for his current weaponry.
The Merchant will be your best friend in this regard, as you pay him Pesetas and Spinels for upgrades and new weapons. Leaving the special weapons aside, every other gun can gain an increased rate of fire, more ammo capacity, and so on. Upon unlocking all upgrades, you can use its Exclusive Upgrade, which provides some powerful bonuses.
However, if you want to use a weapon regardless of its upgrade level, spend an Exclusive Upgrade Ticket. The Merchant will provide one for 30 Spinels.
