I've had this from some Steam sale for a while, and just put about an hour into it. The concept is great - drop your ass off in warn torn Africa and try to take out a target in a free roaming world. The execution, however, is kinda weak.
The map system is kinda cool, but at the same time kind of a huge piss off because you are constantly having to switch area maps/map types...which can be a bitch when the map takes up half the screen. The weapons all feel good...until you start shooting dudes and realize how much damage these shitty ai robots can take...and stealth is never really an option. I was also bored of driving around place to place after an hour and see that there's no real fast travel (there's a kind of half-assed one that doesn't seem like it would help).
I'm probably not going to touch it again, but maybe Farcry 3 will fix a lot of this.
