Wow. For me, this is cutting edge gaming. I like the total immersion in a beautiful, hostile and huge landscape that allows me to explore a variety of habitats in all kinds of vehicles (including a glider!).
The minimal gamer data intrusions on-screen allow for much more of a feeling of entering the African world. On a widescreen HD TV, this is absolutely breathtaking.
Specific game play details are widely available, but I am very satisfied with the array of weapons, confrontations, variable character behavior for repeat play and startling action set-pieces.
The fact that day becomes night, the weather changes, fires left unattended can burn out of control and that weapons age and fall apart over time enhances all elements of this absolutely terrific game. Hard to imagine areas for improvement on this one given the premise.
And let me say again the terrain for open exploration is huge. Must be about 20 square miles of savannah and jungle. That is very big for a seamless open and widely variegated naturalistic landscape.
The mission is simple. You're a bounty hunter looking for an arms dealer equipping both sides of a bloody (tribal?) war.
Oh yes, here's the coolest thing of all. There's a fantastic Map Editor that allows you to design your own level. Yes, create a world of rivers, plains, jungles and structures. There are over a thousand choices! And then you and your friends can enter it for game play.
Highly recommended. This world is hard to leave...
