Ballsy

Ballsy is a secret achievement/trophy in Deus Ex: Mankind Divided and is awarded for getting a basketball through a hoop. It is not available until Adam Jensen is presented with M11: Confronting the Bomb-Maker or M12: The Heist during his second visit to Prague.

Walkthrough
To get this achievement, you must head to the Church of the MachineGod (there may be a bug where you can only get it before going to G.A.R.M., see notes).

Head to the far back area of the first floor into a small courtyard and you will see the hoop and basketball on the right. There are a number of ways to get the achievement. The simplest approach is to put the basketball on the roof above the hoop, then drop it straight down and it should be awarded. You can also try to throw it traditionally if you do not want to "cheat" or the achievement does not pop up, but it may take awhile with this approach.

Trivia

 * This achievement is based on a similar one from Deus Ex: Human Revolution in which Jensen has to get a ball through a hoop in Detroit, and is continued  in the A Criminal Past DLC.
 * This is a continuation of the long-running joke about getting basketballs through hoops in the Deus Ex series.
