This Mod takes place between Portal: Prelude and the original Portal. Its the Year 2009... Glados has a new Testsubject with number #44362881 (her real name is Sarah). This Mod has two different endings. Nothing will be said because the mod is still under development. This is created by Jet-Soft Enterneinment.
