GUYS! DONT CONVINCE TO HIM TO LIVE! LET HIM DIE...In a cool way:
What you will need:
* AK47 with three clips of ammo.
* Five hand grenades
* One knife
* Hand gun with three clips of ammo.
How to:
First, get all these equipments and wait for a week, maybe plan a unique rampage / massacre idea. When friday comes, go to your local school and start killing people with your handgun. When they will try to call the police, you'll have about ten or five minutes to kill as many people as you can.
When the police sorounds the building, throw a few grenades at the youngest to kill more people. Since your handgun's ammo has already run out, use your AK47 and just spray it at random people. The police should be in the building now, so you should pretend you surrender and when they come to take you out pull the last grenade's ring to blow up some cops.
Tips: Try to kill the ones that are begging to live, they won't move so it's an easy target. The ones that are running or panicking shouldn't be shot because you can waste expensive bullets on them.
Result: You should kill about 40 people (including the police and you)
