An unofficial, fan-made expansion mod to Half-Life 2, Transmissions - Element 120, is now available as a free download. Created over the span of two years, the mod's author is now looking to have the project appear on Steam by having it approved through the Greenlight program.
Currently, the only requirement to play the mod is to install the Source SDK Base 2007. The mod's author describes the project as:
Transmissions - Element 120 is a short single player experience set in the Half-Life universe featuring a unique gravity defying weapon that allows you to jump buildings and sustain large falls. The story takes place at a mysterious date & location after the events of Half-Life 2: Episode Two. Where are you? Why have you been sent?
