CDJ75: A little curiosity I noticed. I played both the japanese PC version and US PC version now and in the japanese one, after I finished the 1st and 2nd scenario with the highest rank each I got the weapon unlock notification and the image with text telling me how to summon zombie Brad.
In the US version however I also got the original screen telling me that I now unlocked 4th survivor. Must've been an oversight by the porting team that they left it in, of course nothing happens afterwards, you don't actually get to make a Hunk save like you did in the PS1 version because it doesn't work like that in this version. But still, the unlock notification was still there. Happened after both Leon B and Claire B.
Assuming it is as hard to unlock this screen in this version as it was in the originals, its understandable that GOG team would rather change lines of code to unlock it from the go instead of going all the way to the end with highest rank and good time to know that this screen was left there in the end. Or maybe they knew about it and left it there for nostalgia sake?
Really interesting fact. Thanks for sharing. :)
