Hardcore Mode Idea

So what if in Hardcore mode you can still reprint but you progressively get sicker due to the heavy metels in the water or the virus.
Your health, swim speed, and inventory slowly shrink as you play the game to represent your growing infirmaty.
Reprinting slows this down, and undos a bit but you’re left desperately searching the ocean for a cure before you succumb to your illness.

It always kinda annoyed me in the first game how being infected with the khara never really effected the gameplay, like oh-no your infected with a super killer bacteria but you can still swim for 24hr straight and explore the ocean as much as you want.

I really like this idea and I think it fits in the world while also making the game hardercore.
