I read your thread yesterday. As I love RTS games I was curious what it might be and searched the net about RTS games (mobygames for example, where you can filter for systems, years, genres, subgenres), but I soon knew I would never find it. It's incredible how many RTS games have been developed for the PC during the past two decades (more than 1000).
The developer Overmax Studio, now called Object Software Limited is from China: http://www.objectsw.com/
I've never heard of this company or Metal Knight before you posted the game's name here.
The game does not seem to be very known in the west, it isn't even listed on mobygames (which lists many many PC games). I just found a small entry on the German game museum site thelegacy: http://www.thelegacy.de/Museum/8393/
Anyway: Glad that you found it out yourself. Have fun with your re-discovered game.
