10. Here's How to Complete Mission 10
Modojo.com also posted up some tips on the best way to take down mission 10:
Derek is tired of his boss standing over him complaining all day, and offers you a chance to take him out for 1000 cash. It sounds like an easy job, and will only set you back four charges, but it's in this mission that you'll first have to start compensating for wind.
The first thing you'll want to do is line up your target. Once you do that, you'll see that you need to move your scope a little bit to adjust for height. After lining him up, check the wind compensation - it's at -15. That means you'll want to use the horizontal line on your scope - the left side - and move the scope over to the right. For this mission, a tutorial will show you where you need to shoot after lining up your target.
Set up your scope in the right target area, highlighted in red, and that boss'll be smoking his last cigarette.
