After performing experimental testing on the Portal Gun, Aperture causes a dimensional fracture, tearing open a lattice of unstable antilight dimensions where direction, scale, and causality no longer behave consistently. You are assigned as a test subject to explore these environments, but the deeper you go, the less the tests resemble controlled experiments. Rooms repeat with subtle differences, paths lead back to places you've never been. Instructions contradict themselves. As Aperture pushes you forward, a question emerges: are these dimensions being studied... or are they studying you?

TBA

Outside of the antilight dimensions, much of Aperture will look the same. Inside, however, abstraction increases with depth. The deeper the player goes, the less the world resembles real space. Minimal color usage, void spaces, floating planes. Heavy usage of geometry.
