From Youtube:
"This is something that took me a few hours to put together, but absolutly ages when having to extract and convert all the red alert movie files. I present Red Alert - Hell March, the real introduction to the series. Please comment.

Dedicated to amygdala clicking, which expanded my creativity, deminished my boredom, and is the only true way to experience nirvana and meaning of life whenever you want (a must look up)."

Also here is a link to an open source version of Red Alert called OpenRA:
