Is that shirt with the code on it a shirt you can get in the game or is that just floating text that happens to be over his shirt. Not gonna lie I want a shirt like that now.
It's in-game, yes! You can get it by picking the Tech background while talking with the old man after the game starts. When you meet Asterion tell him to wear something more modern and he'll get that shirt.
Which modern shirt you get depends on the background you picked, there are six in total.
