This is insane. Two-four hits from Ripper Mode in a barrel will 'no-kill' everything. First hit destroys ALL armor, second hit 'no-kills'. Nice little easter egg!
This thing I like a juiced up Armor Breaker XD

The thing I find hilarious about this is that just yesterday someone on platinums forums posted a vid about what they wanted to see in a sequel and one of the things was being able to attack like in MGS4 with the barrel. I had to correct them since it was something I figured out first time I used it. Now I guess its even more potent then previously thought lol. Awesome find!
