Mod DB announces the release of a demo for the Overheid modification for Half-Life 2, which they say requires Half-Life 2: Episode Two. Here's the announcement, which is actually from a few weeks ago: "Overheid is a mod that follows a lesser-known member of the resistance as he makes his way through City 17, and up the ranks of the resistance movement. The demo is an early portion of the game, and includes the first major gameplay climax. It's heavy on combat and action, but the mod as a whole will feature a good mix of exploration, story, puzzles, and combat--similar to Half-Life 2." Thanks Ant.
