What this add-on does offer is a better story line and more units. Some of the new units include jump jet infantry, EMP cannon, mobile EMP, Juggernaut, mobile war factory, limpet drones, mobile stealth generator, and the reaper. These units are a nice addition, but I feel that they should have been included in the original release. I mean, we waited long enough. What's another month or so? I would have to say that these units unbalance the gameplay a bit - giving more of an advantage to the NOD. That's okay because in the original, the GID had the advantage. The story line is ten times better than the original. Again, details that should have been included in the original. In only a few missions, the expansion manages to grab on to and hold on to your attention. By the end, you're board again, but it's the end so it doesn't matter.
Well, it's the same old point and click tactics. Same unit generation, resource management, and building construction as before. I guess once you develop a good engine and beat it into the ground, why not keep using it?
