The "LITE" version, with a ZIP file and Installer is now available!
This version of the mod does not contain the HL2 maps, making it considerably smaller and quicker to download for people who already own Half-Life 2, and discourages piracy. Plus, it has an updated README and a few junk files removed. It's even been renamed from "Half-Life 2 Portal" to the correct mod name.
Have fun playing, and thank you for doing so in the past!
