When I see those videos it just amazing to see how big is the map, when you look at the poster map it doesn't look that big but the game video just show otherwise.
I'm not sur to understand what you exactly mean but it seems like you can climb obstacles. We don't know all the type of obsatcles you can jump but we have already few examples in trailers when they jump on top of roofs.
More or less can I climb straight up to those Coca plantation hills? Or are they too steep even with full of vegetation to grab on and force me to use roads to get on top.
