Unless going for an S-Rank, it’s likely a good idea to spend the extra time hunting down and collecting all the weapons in Resident Evil 2. Some guns and attachments are easy to find, though others, like the Lightning Hawk, can be time consuming to track down.
There are multiple weapons to find across Leon and Claire’s stories, as well as multiple attachments.
Though it is certainly possible to complete Resident Evil 2 with limited weaponry, facing the final boss with just the starting pistol probably isn’t a good idea. Beating Resident Evil 2 is no walk in the park, and players looking to get a decent rank will need to know where to find all the guns and their upgrades.
