Probably the biggest change from the original offerings is the addition of the Japanese as a playable faction. Not only do they get an entirely individualized set of historically-based units, but a full set of missions too. The Japanese missions cover a wide variety of territory, from jungle to urban-type settings. The initial mission is a rescue that has your troops arriving by boat and progressing into the jungle. This mission in particular demonstrates how terrain affects your abilities. When you get off the boat, you have a wide view of the coast leading up to the jungle's edge. Upon entering the jungle, however, your field of view is cut drastically, and the fog-of-war bears down on you.
