Portal: First Slice

What is Portal: First Slice?

Portal: First Slice consists of test chambers 00-10, with a total of 11 test chambers. It was originally available on Steam for any user with an Nvidia graphics chipset. The demo was distributed along with Half-Life 2: Deathmatch, Peggle Extreme, and Half-Life 2: Lost Coast. After some time, it was eventually made available to all Steam users, before being completely removed from Steam during the "Portal is Free" marketing campaign.


Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The main program executable is hl2.exe. The software installer includes 116 files and is usually about 153.62 MB (161,082,512 bytes).
