install it, a score multiplier will show in the top left of your screen. special kills (headshot, double kill, triple kill, multi-kill) show up below it along with how much they were worth.

i wasn't able to fix the bug that cases accidental deaths or kills by peds to add money. the score text only appears if it's <1, the amount of money you get from things has been adjusted because apparently i'm the only one who finds tanks hard to kill

kill - 100
headshot - kill + 150
double kill - 400
triple kill - 600
multi-kill - #of kills x 200
boat/car explosion - 1000
heli/plane explosion - 1000
tank explosion - 100000

i recommend Ryosuke's bullet.asi mod. to be used with this as it allows bullets to pass through peds.
