Transmissions: Element 120 is a free, standalone, single-player modification set in the Half-Life and Portal universe.


Taking place at an unspecified time and location after the events of Half-Life 2: Episode Two,[1] the modification features a device and weapon called the Zero Point Energy Projector, which allows the player to perform jumps of great heights by launching energy orbs while mid-air; the projectiles can also be used to land safely, take out enemies, and destroy barricades, windows, and fences, among others. The Projector is powered by Unbinilium, hence the title of the mod.

Transmissions: Element 120 introduces new gameplay and storytelling elements. They include QR code stencils readable using the HEV Suit's zoom function, clipboards describing the backstory, Combine lock breakers, and light-related puzzles, which primarily revolve around phosphorescent symbols sprayed on walls, as well as the Zombies' inability to sense the player's presence in the dark, and the Sentry Turrets being non-functional in unlit areas. Additionally, most of the environments are highly interactive and destructible.


Being mostly the work of a single modder known as Shokunin, and featuring custom levels, code, models, and sounds, as well as improved lighting, physics, and AI, the modification had been in development for over two years before being released on March 29, 2015.[1] It appeared on Steam Greenlight and got approved by Valve within the following two weeks. On June 16, 2016, it was made available for Steam download.


Transmissions: Element 120 has gained critical acclaim since its release. With the author's post on the /r/gaming subreddit reaching almost 5,000 upvotes and over 1,000 comments, the mod's release was noted by several major gaming websites. The author was also offered a job interview at Gearbox Software.[2]

Kotaku stated that Transmissions: Element 120 "is damn near Valve-quality," praising its absorbing gameplay and thrilling Zombie sequences.[3] According to Rock, Paper, Shotgun, the most enjoyable aspects of the mod include the Zero Point Energy Projector, the level design, and the destructible environment.[4] ValveTime said that Transmissions: Element 120 "looks great and has evidently been constructed with real care."[5] However, the mod's short length was noted by several reviewers, including Alice O'Connor of Rock, Paper, Shotgun[4] and Christopher Livingston of PC Gamer.[6] As of August 2016, user reviews of Transmissions: Element 120 on Steam are very positive, with 94% of reviewers praising the game one way or another.[7]
