Completed Resident Evil 3.
The final episode, Factory, is obtrusive. It may sound funny, but there isn’t that much backtracking in Resident Evil 3. Unless you get confused, of course. But Factory is designed is such a way that you have to go back and forth multiple times, while game throws at you enemies in rooms you already cleared, sometimes twice. Also, there are some unskippable cutscenes before the boss fights that can get pretty annoying.
I’m not sure how environmental the final two boss fights are. In the first, Nemesis is in humanoid form, and you need to shoot acid valves when he’s near. Not sure if that’s the only way to damage him, or if it just helps. Funny how at some point he loses his head, but still goes on.
Then the final fights is against Nemesis-frog. I usually say that ammo is more important than health items in Resident Evil, because you can’t heal a boss to death, you need to shoot him. But this is another environmental fight, as far as I can tell, where you need to turn on a railgun, then lure Nemesis a couple of times so it gets smashed by it.
The entire game took me around 6 hours of game time to complete. Which isn’t bad, I thought it would be shorter. I remember that Leon’s scenario in Resident Evil 2 took me around 2:30 hours.
By the end of it, I still had plenty of healing items, but not that many bullets, I must admit. So the game is more enemy heavy than Resident Evil 2 for sure.
