The Adversary was a new prototype in development in 2002 for XBOX and PS2 by the same team at Namco USA that worked on Kill.Switch (an average third person shooter, but with interesting and innovative “hide ‘n’ shoot” elements). The project started as another third person shooter with human soldiers, but it slowly evolved into a more complex concept, untill in the latest builds there were even robotic tanks and mechs fighting in a big city. At this time of development, the project took the new name of “City Under Siege”. The game was created with emphasis on multiplayer deathmatches and it seems that a playable multiplayer demo was even available at closed doors at E3 2004. City Under Siege could have been a fun game, but sadly it was cancelled by Namco for unknow reasons, maybe because it was too risky economically.
