have you checked out the demo yet, If you have a ps3 you can get it on the psn network for free. controls are a little different, but there is an option to make the controls like the 4th game. I love the games but am a little rusty on the story lines, maybe you can help... wasnt chris redding dead???
Chris never died in the games. Anyways, for a full overview, its pretty hard to explain in one posting with over 6 games to cover (I include game 0 and Code Veronica). I recommend checking out a fan site and/or Gametrailers who is holding a complete Recap of the series. Sadly, I lack a PS3 or an Xbox 360 so I won't be getting the game anytime soon. However, I'll probably buy the video game guide book to get at least a full scope of the layout, the story, the enemies, and everything so I can get at least some taste of the game.
