Half of the game takes place in the Raccoon City Police Department, while the rest of it sends you underground through the sewers and into a secret Umbrella lab. Both campaigns have two scenarios, giving you four possible playthroughs that have some smart overlap with one another.
What’s interesting about this game is that it has two campaigns total, each from the perspective of Leon and Claire. This game puts you in the shoes of police officer Leon Kennedy, along with Claire Redfield who is searching for her brother Chris (from the first game).
For this, 2019’s Resident Evil 2 remake is much closer to the original in terms of content, so you can get away with skipping the original if you want a user-friendly experience. Just after that are all of the events of Resident Evil 2.
