Ok, so I've nearly beaten this game on PC, I collected all the souls and opened the 10 gate, and I get the Book of Shadows. According to the walkthroughs (which are all for N64 apparently) the only version that gives you that is the PSX version (which was horrendous by the way). So has anyone else had any luck getting a second violator on the PC, or is that something peculiar to the N64 version?

yes on pc version you can get a second weapon.you have to set the cheats on.(invincible ulimited ammo and so on .

Shadow Man
Cheat mode:
Enter the "data\scripts\menus\english" subdirectory in the directory
where the game was installed. Rename "release.msc" to "release.ms1".
Then rename "debug.msc".to "release.msc". Load the game to access a
cheat menu with invulnerability, all weapons, all items, infinite
ammo, level select, and other options.

Hint: Nettie bleeds:
Go up to Nettie. After she tells a story of your journey or fate,
approach and shoot her. To see her bleed, press Snipe then look down
at the bottom part of her clothing. You will se a sprinkle of blood
coming out of her.
