NBA Live 10

Fun achievement to get, also easy and fast.

a) Go to Play Now and select any two teams. (You should be a team like the Heat, Cavilers or Lakers)

b) Now set the Quarters to 12 because once you do ten dunks you will unlock this. Also set the difficulty to rookie.

c) Now with D-Wade, Kobe or LeBron, just drive in with some dribble moves, and since it's on rookie, it is basically always an easy dunk with these 3.

d) It doesn't just have to be with one player, can be with whole team also.

e) If you can't unlock it like this, just go to the sliders, and make dunking to the max!

To do a dunk you charge at the net by holding RT down, and then as you get close press and hold X.

After you get your first, you'll get the "Come Fly With Me" achievement. Then just repeat 9 more times for this one.

Note that you can do this on any difficulty, with any player, and can adjust all sliders in your favour.

Personally I found dunks to be really difficult with Lebron James (he kept getting boxed out), but trivial with Kobe Bryant (he'd literally leap over guys). Might as well do this while playing as the Lakers vs the Raptors, as you have to score a ton of points with Kobe against the Raps for the "Kobe's 81" achievement (and if you do that, you might as well score another 19 for the "Stilt 100" achievement).
