I’ve completed the last few levels of this game’s campaign yesterday. As it turns out, after the second six missions in Tokyo, I had to return to Baghdad for two more missions before it was all done. I also unlocked several more units, but in the end, all I used for the last few missions was the shield generator, a tank, a dragon and two missile launchers. I simply seemed more effective to get as much damage as possible and use my commander unit as an extra decoy for when it’s needed.
For now, though, I mark the game as “completed”.The last mission was hard, but I found the mission before that slightly harder, with more enemies and more need for my suit abilities to keep my army alive. Still, both were pretty tough to get through, even at the casual difficulty I played at. From what I can tell, there are achievements for beating all the missions on a higher difficulty, so I might have to revisit all of them eventually. There’s also extra game modes I can try out, as well as achievements linked to those modes.
