This sound is a beep like heart monitor, i created with an audio editor, i used cine wave 5000 hz with intervals of 500 ms betuin the beeps i also aplied a soft reverb. Unfortunately this people dies on the end. Sad.
Some take of dices shaking in hands and rolling on wood's table (sort of dice d4-6-10-12-20) at the end, shaking and rolling of 3d6 (players of ins/mv, you know).
