Residual Error : City 34 (Vol1)
Residual Error : City 34 (Vol.1) is a mod by Toxagen - the author of Residual Point (2007), Residual Life (TBD) and Antagorism (HL2).
This mod is assumed to have been made by a group of Korean modders.
The player starts the mod with no clear objective or goal. By trial and error the player eventually finds access to a suit room where they don a Combine Elite suit. Again, through trial and error testing doors and forcefields the player makes their way to the surface only to find Zombies, Combine and rebels against them.
