Mikami said he selected the survival horror genre in order to live up to his fans expectations, and because it was one wherein he felt “most adept”. Few details were given about the actual game, except that planning started in 2010 and it will mostly likely be released for HD consoles. As for the name, Mikami explained it means the number 2, but that it really has nothing to do with the game's content. 
15 Points/ Bronze TrophyKill an enemy with each weapon type including special weapons.The gun types that you’ll need to kill enemies with are Pistol, Shotgun, Submachine gun, Assault Rifle, Sniper Rifle, and Light Machine gun. These can be bought as well as found from the Spec-ops enemies throughout the campaign. The two special weapons are the Grenade Launcher and the Flamethrower. Each can be found throughout the campaign in certain special weapon cases. Among other places the two weapons can be found, the flamethrower can be found in a case atop the walkway, directly above and to the right from where you enter the very first room. The grenade launcher can be found in the very last room of the game while fighting against the “boss.”15 Points/ Bronze TrophyAttempt "The Rescue" and survive.During the last chapter, you will be given the choice of defending or hunting Leon.

Do that five times and this will be yours.
