'''''Portal First Slice''''' was the demo version of ''Portal''.

== Overview ==
''Portal First Slice'' consists of Testing Track|test chambers 00-10, with a total of 11 test chambers.

It was originally available on WikipediaSteam (software)|Steam for any user with an Nvidia graphics chipset. The demo was distributed along with ''Half-Life 2 Deathmatch'', ''WikipediaPeggle Extreme|Peggle Extreme'', and ''Half-Life 2 Lost Coast''.

After some time, it was eventually made available to all WikipediaSteam (software)|Steam users, before being completely removed from Steam during the "''Portal'' is Free" marketing campaign.

== Trivia ==
* The origin of the title ''First Slice'', is a reference to the cake that GLaDOS proposes to Chell, what was thought to be a major ruse, and was turned into an internet meme, but was seen later in the game.
