You begin at the highest building of Los Santos, buy you don't know how you get there. When looking around you see a new kind of bank. And think in yourself let's rob it. Then you go to the bank, enter it and kill the first guard. Then take the money and there is another guard coming, you must kill it too. Then you leave the building and you have wanted level(Easy:3 stars. Medium:4 stars ans Hard: 5 stars). Outside you must enter a car and drive back to Grove Street.

Thanks for your comment I'm making an other version of the mission: Medium and Hard. Medium: 1 Guard can't be killed with a headshot and both guards has more health. Hard: Both guards has maximum health and can't be killed with headshot + Higher wanted level.
Update New work in progress: I'm making now the medium and hard version of it.
Medium: 1 guard can't be killed with headshot, both guards have more health, and wanted level 4 after robbing.
Hard: Both guards have max. health and can't be killed with headshot, after robbing 5 stars wanted level and your escape car(after robbing) isn't indestructible anymore.
