Water Hurt
As in GTA IV and SA, even if jumping from 1, 000, 000, 000, 000 meters won't hurt you if you get in contact with water.

Well I decided to change that with a small CLEO.

An amount of health will be taken from you after landing in the sea, which is equal to the distance between the water and you / 1.5.

CLEO is required.
