The action takes place on the streets of Raccoon City, where Claire Redfield, looking for her brother Chris, comes across Leon, a cop on his first day at the job, while zombies assault them both. It's not long before they get separated... and then reunited. And then separated again.... While both Claire and Leon go their separate paths, they do collaborate via radio. There's two ways to play the game, Claire A/Leon B or Leon A/Claire B, but it's not as interesting as it sounds. While Leon and Claire meet a different supporting cast, most of their puzzles are the same, it's just the location of a few items that changes. And while scenarios are called 'A' and 'B', they are basically the same, but scenario B is a bit tougher with even more zombies, sometimes even substituted by tougher enemies, and the addition of new bosses, including one that reappears every now and then to annoy you. Basically, you get two play 4 variations of the same thing. There's a few other differences between Claire and Leon, like the weapons they find. Leon gets better all-around weapons, with a gun that holds more bullets, the ever-useful Shotgun and the extremely powerful Magnum... and he even gets to upgrade them! And there's a few segments in which you get to play as an alternate character, Leon's has a gun to defend herself. Meanwhile, Claire gets a gun that holds 13 bullets top, can't be enhanced, and the very situational bowgun that can't hold a candle to the shotgun.... but she also gets the Grenade Launcher, which is extremely powerful, covers a wide area and is very versatile thanks to three ammo types, but the alternate playable character on her route can't even defend herself, and without spoiling too much, you even have to babysit her, run too fast and she'll stop dead on her tracks, and if she falls too far behind you won't be able to enter a different area. All in all, Claire's scenarios are definitely harder.
Savespots are rather uncommon, so dying hurts a bit, since it potentially means redoing minutes, upon minutes of gameplay. But there's a slight advantage to dying, now you should be familiar with what you have to do, and where the enemies are, so it's easy to learn and do things better the second time around. Now you know if going towards that dead end is worth it, maybe going through three zombies to get a healing item you don't need isn't really worth it. And that's the beauty of how the game works, you'll learn the environment, you'll learn to lure zombies, and run past them, without wasting a single bullet on them, so dying isn't all that bad, most of the time anyways.
I found Resident Evil 2 to be immensely entertaining. But as fun as it is, and I do recommend doing an entire A/B run, since there's different bosses and a few new areas, unless you really, REALLY like the game, doing the alternate A/B run back to back isn't really worth it. It's the same game, two more times. That said, for future playthroughs, it adds replayability, so it's not a bad feature per se.
