This mod is about a scientist at Aperture during the making of GLADOS. in many ways it is a prequel to Portal Prelude
the new feature so far are rooms that can be seen along the hallways with people working. this has been added to crate a scenes of realism to the world in which you play in. the rooms contain the new science team, science equipment such as computers monitors etc. the rooms cannot be entered but are there for detail
This is just a playable demo to see what people think of the level aesthetic
Looks nice
This looks very promising
