Restricted Sprint?

[MyRedNeptune]

I read in an interview, that when it was first implemented, going insane had real gameplay repercussions (like decreased walking speed or something like that). However, Frictional felt that this was more annoying than anything else, so they reduced it to an almost purely atmospheric feature.

I think this could also work for fatigue. Like, say, you're running away and you start hearing your characters heartbeat become faster and louder at some point, you hear his breath become ragged or maybe other sounds get muffled and you get that ringing in your ears you sometimes get when you're close to collapsing. The point being to make the player feel like he won't be able to go on for much longer without actually enforcing it. It could add another layer of tension to chase sequences without being frustrating and risking more frequent player death.

I actually love this idea. That would seriously make for a fantastic atmospheric feature!
