This collection brings together fully custom and unique experiences where Aperture Science collides with other iconic universes through the impact of events native to their own worlds. Each map immerses the player in a version of Aperture reshaped by key incidents and histories from parallel realities.

What if Aperture Science coexisted with BNL, Fazbear Entertainment, or Cyberdyne Systems? How would Aperture evolve if shaped by the dystopian future of BNL, the twisted legacy of Fazbear Entertainment, or the rise of Skynet?

The Aperture Multiverse explores these alternate timelines, where the fate of Aperture is rewritten by the defining events of other worlds. Each map offers a distinct narrative and atmosphere, blending Aperture’s core identity with the unique DNA of these intersecting realities.
