It was make by the same developer as Yakuza, the newly formed Ryu ga Gotoku Studio. Since I really love Yakuza, specially the awesome Kiryu, I should give a try to this new free demo, lol.
To the demo, I was annoyed by the control at first XD But that's because I'm not use to these kind of control at all (Third Person Shooter). After the first try, and replay the demo again, it runs alot more smooth :D
I love the idea of talking to your partner, and that you are not alone in the battlefield (which will be extremely unrealistic..). But the most annoying part, or maybe even funny to look at, is... how dumb the AI are LOL They just run at the same place, or in circle.. get slap by Bosses XD Ohhhh... god, I didn't even know if I should get mad or laught hard about it, lol.
Here is the first part of the demo, there is training, and 2 maps. Both with (mini?)boss fight in the end. While the first map you have to beat it to finish, the second map only show a short battle with the boss.
