For this achievement you need to get 10+ points in 3/5 of the following categories with one player:
Points
Steals
Rebounds
Assists
Blocks
Firstly as you will have already done you want the
user sliders set to max (Bar injuries) and the
CPU sliders to minimum.
At the same time go into the
NBA Rules menu and turn the following OFF:
Shot Clock
Out Of Bounds
Backcourt
8sec Half Court
3 In The Key
5sec Back To Basket
Now with these rules off pick the player you want to get your triple-double with and get possession of the ball, make sure you steal the ball from your opponent at least 10 times.
With possession of the ball run (
) into you half of the court and behind
your net making sure to stand in front of the pole for your basket, press the
button to shoot which 99% of the time will hit the back of the basket and land near you,
this counts as a rebound even though it is off your own net. Now run to the opponents net stand in the 3 point zone (Outside the red line) and hold
to shoot (With the sliders all the way up you will always score)
Repeat this a minimum of 10 times with the same player and you will have you 10 rebounds, 30 points with one player and 10 steals with one player giving you a triple-double, though it is advised you go for 20 rebounds to gain the other achievements.
You will also get the following achievements whilst going for this:
Score more baskets till you have 140 points and the game will also be complete.
You can check the stats by pausing, going into Game Stats - Home Team.
