I was just thinking about this - What if there are no 'save rooms?'
We know there's typewriters to save the game, but save rooms have always been a sanctuary from all danger. Even Nemesis couldn't bust through the save room door in RE3.
But what if this sanctuary was completely removed? I'd increase the tension of the entire game.
*Zombies can follow you from room to room.
*If you're low on health/ammo, you'll have to run around franticly searching for bullets or green herbs as they chase you.
*No place to stock up on ammo and confront the enemies afterward.
Also, from the demo, we've seen there was a zombie in one of the lockers, in the area where the save room was in the original RE2.
It'd suck to not have the classic save room theme, but that's a relic of another time.
Besides - we can listen to it anytime we like, on YouTube.
