I noticed that this game has elements of Urban Reign, Absolver, Yakuza and God Hand. I know the IGN hands-on video said there is some Arkham/Sleeping Dogs, but that looks and plays better than either two. Especially the former. The Urban Reign elements I see the environmental interactions and crowd control. Enemies are aggressive and defensive, and you can't button mash your way through them. That is where some God Hand elements come in too. The Yakuza elements is when certain mooks get there own heat bar/stamina when they are guard broken enough or take a certain amount of damage. It's not randomized like the demons in God Hand, but feels similar.
As soon as this game is up on PSN/Digital Stores for pre-order, I am putting the full amount down. This game is looking to be the equivalent of every Hong Kong martial arts movie/Jackie Chan film, The Raid, and Old Boy. Neat.
