Overview
Stuck at getting the Joker achievement? this is how u get it!
Part 1: At the beginning
Just after you start the 1st chapter, ho to the university (well after you take a shower of course)
go straight up to the entrance of the university and get inside and upstairs. than go right to the room of your beloved professor and klick on the nameplate on the left side of his door to get his phone number. after that go out of the university entrance. still in front of the university, use the phone to the right, and choose the first two dialogou options.
the first is a simple telephone prank that makes the prof saying i am an idiot.
the second is a “quiz” that ask the prof who the inventor of the telephone was.
Part 2: After the warehouse/Garage
after you get back from the warehouse/garage, its afternoon and the sun is about to set. like the first two jokes, the last is made at the telephone again. just use it and choose the first option.
it should be something about the mom of the prof coming to visit him.
after this, the achievement should pop up.
Not Unlocked?
It looks like, for some people, that the achievement only unlocks after beating the game for the first time. Since I can’t confirm this on my own, unless I use some kind of achievement unlocker or some other third party software, I include this information as a “maybe you have this problem”.
For me i got this achievement last of all, after i finished the game several times for the speedrun achievement. So as I was looking for the jokes, i stumbeld upon the first two telephone jokes. After I made the third dialogue the achievement unlocked instantly on the spot for me. I can’t guarantee that the achievement will unlock like that, but those lines are definatly the ones required, since I only klicked on those options out of the keylines needed to finish the game. Well if the achievement doesn’t unlock on the spot, just finish the game (well, at least the first chapter^^) and it should unlock.
