I loved it. I have played the demo 5 times already. Each time I go to a different place.
I have found 3 bases, 2 colonels, used choppers and a plane already.
I really really like open world games. The grappling hook is awesome. Makes traveling real fast combined with the parachute.
I had been talking about this game, but in the PS3 Trophy League. I guess people want GOW3 or FFXIII, not this. lol
But I will be buying this game, Day 1 (well, a few days after since I live in Brazil )
