Here is the full list of all 23 Sunlight Scream: University Massacre achievements.
Welcome to Sunlight City!
We're all a little masochistic
It was close, but not close enough
It's definitely over now
Dangerous acquaintances
What a strange dream...
And I just wanted to swim...
Win Samantha's heart
Grades aren't the point, right?
I want to play a game with you
Hanging out with Leon
Do a search and don't get caught
Your nerves are enviable
It's a nice view, though
It's all about knowing how to use it
Chess came in handy after all
Win Erika's heart
Win Sarah's heart
It's time to light up
Murders are not an obstacle to romance
The party's in full swing
Everything happens for the first time sometime
Why so easy?
