I didn't care much for this. It was weird how you divided an intro into different parts. That just seems short enough for a single submission. It doesn't even seem like an intro. It was at least nice to see all those Doom guys. Granted, I'm not familiar with the series that much.
The music seemed pretty good. The animation just isn't that good. It looks quite dated. I'm glad this was released as a full intro. It just didn't engage me.
