Codename: Gordon is a 2D side-scrolling fan project based on the Half Life universe and programmed in Flash. In this fast platformer, you assume the role of Gordon Freeman and travel through six chapters inspired by the environment in Half Life 2. All the familiar weapons and enemies are present: crowbars, pistols, grenades, the SMG, a manipulator gun, headcrabs, zombies, the infamous G-man, etc. The game even includes a fully functional buggy.

The game's controls resemble a 3D shooter. You use the keys to move and the mouse to aim (similar to Abuse), there are medic and HEV recharge stations and even the weapon selection boxes feel as if you're playing the real 3D game. Furthermore, it also features a highscore system with network support and some secrets to discover.

Valve reported on June 18, 2004, that 600,000 Steam users had downloaded Codename: Gordon in the first three weeks of its release.


Gabe Newell, in an interview with HomeLAN, said that the original plan was to release Codename: Gordon on April 1st (April Fool's Day) with a message saying:

Due to tremendous pressure from the gaming community to ship Half-Life 2, we looked long and hard at the game to see if there was anything we could cut that would let us ship sooner. It looked like if we cut the third dimension, we'd be all set, so after five years in development, Valve and Nuclearvision proudly present Half-Life 2D.


In 2008, the game was removed from Steam, since the developer has gone bankrupt, and their website (the link to which is hard-coded into the game) has been taken over by cybersquatters. It can, however, still be downloaded from Steam by typing steam://install/92 in the web browser's address bar.
