Problem is, I can't remember the title. The game was released somewhere around 1998 and 2001 and plays in 3rd person. You are this non-transforming robot that walks around in a huge city. You have several weapons at your disposal and must destroy waves of tanks, helicopters and onfoot soldiers. I think there were other robots too, but I can't remember. I do remember that you could squish soldiers by walking on them and climb building. This was around the same time that Shogo was released (FPS transforming mecha game). Unfortunately, the game wasn't a huge success, as it had its fair share of bugs.
