Currently an Games Art Student and we had to collab with the Game Programmers to create a new game.
Summary : Imagine you were wandering normally around Earth and suddenly . . . you no-clipped through the floor and enter the backrooms. You now need to find 4 paper notes scattered across the map, find a keypad which is next to a door.
Memorise the code on the paper to get to the 2nd Level.
