Bloody, Violent, unrealistic... Cool.
This reminds of a Chuck Norris or Steven Seagal movie where it's impossible ot kill the main character. It's rather cool but overused gimmick. Only here you made it more violent and cool looking. I personally like the whole "I'm one man using a hundred guns and killing you all with them." act but it wasn't long enough and maybe next time more guns can be used to keep the viewers interested. The Steyr TMP was a very nice choice in the video. The M3 Super Combat Shotgun was a good choice but not used much. Maybe next time you can add an M4a1 Colt Carbine or a XM1014 Auto Shotty. The Samurai sword was cool and very violent, but I'm more of a gun man. The movie was good though. Keep it up and perhaps you can make another similar to this or better yet a sequel.
