This new video from PlayStation Access takes players on a virtual helicopter ride from one end of the map to the other.As stated previously, Just Cause 3's world size is not necessarily larger than Just Cause 2's, though it's supposed to feel more "dense" than its predecessor."Just Cause 2 was already enormous," game director Roland Lesterlin said.
