Approved! Fine cinematic series.
[+]The environment is pretty OK.
[+/-]The lore seems to have it's roots based on Warcraft III lore, thus not totally original. Still original enough, though.
[-]There are some bugs. Most notably the lightning cage, which has been mentioned already. Also, please do not display the victory message, it is annoying. I understand it's purpose, however, you should instead add a key (ESC for example) to stop the cinematic.
Also, please upload the campaign file only when the series are totally complete.
My rating for this is 7/10, which is approximately 4 (Recommended).
