Don't get scared too much or your blood pressure will rise...
About this Mod
Heart Attack!
Heart Attack! adds blood pressure, also referred to as "Fear Meter", that rises when the player is, well, scared. Or at least when you should feel scared.
If your blood pressure gets too high, you risk a heart attack, so be careful!
