The mod will show the laboratory at a time, when people worked in Aperture. You are one of the test subjects, who came here for $60. But during the tests, unexpected accident happened.
The map is made from scratch and has many differences from the original map.
deja vu
The map made from scratch with the changes, plus it is not destroyed, because it is the 70s.
Looks great! Really want to play the mod.
Always dreamt to revisit the same places from the old Aperture at its heydays.
