You can stagger him, but that's about it. It's not a big deal if you waste a few bullets by shooting wide or dump a few into a deathless bullet sponge like Tyrant. When the nightmare scenario happened-completely running out of ammunition-I had to run from a few zombies instead of fight, but the ammo was there whenever I really needed it. Resident Evil 2 is an insanely well-balanced game. It's a really useful map! Ammo Locations: Why Wasting a Few Bullets Is Not a Big Deal (Really)
Once you've found an area's map (they're usually pinned to the wall in an obvious location), rooms you haven't found yet will appear, outlined in white. Hover over it and text will reveal exactly what kind of puzzle it is. Puzzles also appear on the map as an exclamation mark icon. Once you leave a room unexplored, the items you've left behind will appear in miniature on the map screen.
A red room means you still have some exploring to do. A blue room means you've collected all the items. There's nothing more useful than the Resident Evil 2 map.
