After the team behind ''Tag: The Power of Paint'' joined Valve in the summer of 2009 to implement their paint mechanics, the flaws of ''Portal 2'' started to become apparent. The game at this point had six different testing tracks that made it challenging to maintain a reasonable difficulty curve, relied heavily on the nearly indistinguishable personality cores, and had no settings other than the destroyed test chambers. For these reasons, Valve decided to abandon the Core Hub and rework ''Portal 2'''s story.

A screenshot of the Core Hub and the Morgan Freeman Sphere

The Core Hub Era was a period of Portal 2's development that demonstrated Valve's second attempt at creating a follow-up to Portal. This period is characterized by the Core Hub, a hub world that interconnected the game's testing courses, and the player's goal of retrieving various personality cores.[1]

Summary

The Core Hub Era began in January 2009 and displays Valve's earliest efforts to write a story for Portal 2 that took place after the events of Portal. Though Valve had succeeded in creating a large number of new features and test chambers for Portal 2 during the Experimental Era, the writers still had no solid foundations for the game's story. That was until they were inspired to base the game around the personality cores and their interactions with the player.

In the versions of Portal 2 that were conceived during the early periods of this era, Chell did not return in the role of the player character as the writers believed that her story was self-contained and had been completed in Portal. Instead, the player character at this point was Mel. However, Mel ended up being replaced by Chell after playtesters disliked that GLaDOS did not recognize or remember them.

After the team behind Tag: The Power of Paint joined Valve in the summer of 2009 to implement their paint mechanics, the flaws of Portal 2 started to become apparent. The game at this point had six different testing tracks that made it challenging to maintain a reasonable difficulty curve, relied heavily on the nearly indistinguishable personality cores, and had no settings other than the destroyed test chambers. For these reasons, Valve decided to abandon the Core Hub and rework Portal 2's story.

Aftermath

While the Core Hub was scrapped in favor of a more linear experience, the idea of the game centering around the personality cores survived much longer and persisted into the Multi-Core Era. The idea of a hub world was reworked into Portal 2's co-op campaign, albeit without the nonlinear aspect.

Gameplay

During the Core Hub Era, Valve planned to include six testing courses that were each related to a different game mechanic (e.g., lasers, slowfields, and catapults). Early versions of the Core Hub allowed the player to enter any of the testing courses and progress through the game in a nonlinear fashion, but later versions required that the player complete the testing courses in a particular order.[2][3]

  • Late Core Hub Era Chapters
    • Chapter 1: Intro
    • Chapter 2: Lasers
    • Chapter 3: Slowfields
    • Chapter 4: Catapults
    • Chapter 5: Light Bridges (known internally as Walls)
    • Chapter 6: Mixup

Slowfields

Slowfields, also known as Aperture Science Self Esteem Fields, were experimented with during this time. Passing through a slowfield would slow time, giving the player extra time to place portals and react to puzzles that would normally require quick reflexes. A folder named portal_slowfield exists in retail Portal 2's vscripts folder and contains scripts related to slowfields.

Story

"You have breached the central core of the Aperture Science Genetic Lifeform and Disk Operating System. Pre-Apocalypse, this would have been an act of criminal trespass and an opportunity for you to go to prison. As it is, however, this is a rare opportunity for you to become an honorary Aperture Scientist. Do you see a power object? The Enrichment Center invites you to pick up the power object and plug it in. Something will happen. Something wonderful."
