Gaming since the early '80s I've encountered every style of game and many thousand implementations of them. This game is easily one of the best I've ever played. It looks good, it has a story to it, there's a lot of variety in how you engage its various challenges and it offers many of those.

Despite that, it doesn't lose touch with a core essential element for a computer game: It's bloody good fun!

Wholeheartedly recommended. Play it, love it, play it some more.
