How’d you originally find this? Were you just looking around? There’s a lost animated film called “Doom Engine” that was made by a University student up in British Colombia for his final project that he uploaded on Youtube that I wish I could find now. It’s another one of these that this reminds me of
If you look at all my post I've been bloging a lot about these animations so now YouTube recommend me more of them.
Saddly, called the same way as a really famous game it's almost impossible to find.
Make a comment on hive where you explain every detail you know about this animation and sometime you come back there and maybe you rember a new detail and then maybe someone else will rember it too and find it somewhere.
