Ballsy is a secret achievement/trophy in Deus Ex: Mankind Divided. It is awarded for getting a basketball through a hoop that's not available until you are presented with the choice of either doing M11: Confronting the Bomb-Maker or M12: The Heist during the second visit to Prague.
To get this achievement, you must head to the Church of the MachineGod (there may be a bug where you can only get this before going to GARM, see notes).
Head to the far back area of the first floor into a small courtyard and you'll 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 don't want to "cheat" or the achievement doesn't pop, but it may take awhile with this approach.
- This achievement is based on a similar one from Deus Ex: Human Revolution in which Adam Jensen has to get a ball through a hoop in Detroit.
- This is a continuation of the long-running joke about getting basketballs through hoops in the Deus Ex series.
- While you can enter the Church of the MachineGod during Martial Law, either due to a bug or linking this achievement to M11/M12, one may not be able to get this when they get back from GARM, so it's best to do right after The Heist or during Confronting the Bomb-Maker.
