also, the video was edited to show picture in picture views at some points to show different battles. particulary cool is the shot where the ogres are fighting the knights in the woods, while other human archers line up outside the forest and shoot flaming arrows setting the woods ablaze, then watching in the small picture the fighting turned truly chaotic as everyone was catching fire and still fighting amongst the flames
Credits for the video go esto Ruliweb of course, I'm just mirroring the file because downloading such a monster of a video from them is definitely not cool. Took me 4 hours for that one, with a source modified linux download accelerator.
