Codename: Gordon as well
Codename: Gordon is a flash-animated side-scrolling game developed by Paul Kamma (X-Tender) and Sönke Seidel (Warbeast) of Nuclear Vision. It was offered through Valve's Steam platform. The game was released before the official release of Half-Life 2 as a kind of advertisement and was accessible for free to anyone with a valid Steam account.
Codename: Gordon is an alternative interpretation of the Half-Life 2 storyline, where the player controls Gordon Freeman in and around City 17, fighting so-called Combine units, alien-like headcrabs, and other enemies while meeting allies such as Alyx Vance and Eli Vance. Codename: Gordon differs from the well-known Half-Life 2 because it is only two-dimensional. The player uses the keyboard to move the character left and right and to make it jump. The mouse can be used to aim 270°, but the area directly under the character cannot be targeted.
Unlike the three-dimensional Half-Life, the player is able to communicate with allies. The allies speak in complete sentences (Codename: Gordon has no voice output), Gordon in contrast "answers" by using IM typical emoticons, such as ;-( and ^_^.
The game can still be downloaded for free from Steam, because it belongs to package 0 and thus is automatically owned by every account
