His right eye is hurt which is consistent with Big Boss. But BB doesn't lose an arm. But since it's a dream, he could be experiencing Liquid's phantom pain after he lost his arm after he died. Which sounds weird. But, it's Japanese and, more specifically, Hideo Kojima, so weird is the order of the day. Regardless, it's definitely Metal Gear related. I just hope it's next gen because I'm tired of seeing new games try to do too much on this ridiculously outdated hardware.
