Nice production.
The first thing that strikes me, listenning to this, is that the lead synth parts aren't really fleshed out as much as I'd expect them to be... don't get me wrong, they're there and they've been chosen well, but I think you might need to fiddle with some volume changes here and there.
I really like the baseline and percussion samples you've used. The whole production is very crisp... I'd have made it loop or given it a dramatic ending or something... but that's really just nitpicking.
Criticality aside, I've always loved this song. Capcom's sound team is nearly unparalelled and when they do an adrenaline theme, they do it right. ^_^
I voted '4' for this.
