Tier 3 is an upcoming mod for Portal and Portal 2, it will take place in the year or so before Portal. Kat, the main character, is an elite test subject raised for the sole purpose of being the perfect test subject. Over her many years of testing, she has exhibited the kind of behavior GLaDOS hoped for. However, the Aperture Science Handheld Portal Device is nearly finished and Kat yearns to see the outside. After all, GLaDOS won't need her after she can finish the ASHPD, right?

Behind all the mapping and technical issues to do a mod one crucial pivot is the story behind of it...

Posted by on

So we took a lot of care of the development of the main character Kat, and the way she came to be a test subject in the Enrichment Center facility. Part of that intensive work beside the plot, the music, and of course the mapping was the concept design to test where the atmosphere of the story could lead to.
We are totally aware of the fact that most of this is not to be seen when finally the mod is ready for playing. But without this work the mod will probably lack of a soul which we like to put into, and to share...
