The video tells about the past glories and fights against the Burning Legion led by Sargeras himself using powerful force of Mannaroth and some other Demons.

Also, you can see a couple of scenes where the Demon Hunters (Night Elf Sentinels) are fighting against the corruption of the forrests.

In general, you can see a lot of environment and smooth camera collision and path; those clips are made by Machinima Tool.

You can expect even more videos like that from me in the near future.

Cheers!!!
