About Portal: First Slice?

Portal: First Slice is a collection of 11 test chambers, specifically test chambers 00-10, initially available on Steam for users with an Nvidia graphics chipset.

Following its initial release, the demo became accessible to all Steam users before it was ultimately removed from the platform as part of the "Portal is Free" marketing campaign.
