portal prelude mod

A new Half Life 2 mod is underway called Portal:Prelude, which is exactly what it sounds like. The huge mod (19 test chambers and 400 lines of dialogue) is a fan-made prequel to last year’s beloved Portal, and will be completely free to download.

The project seems ambitious and terribly impressive. They’ve even been contacted by Valve, which is more than some of us who work with the Source engine can say… If you’ve played Portal, I’m sure you’ll be interested in this.
