I played the first 3 missions.
I have to say that this is one of those 20 minute ports. They took the psp version and then just ported some of the stuff to ds.
There is no music during battles. There is real story that make sense. There is no real
tutorial. They just throw you into the game with little presentation and little story. It's really half assed.
The units say only a few words
The ai turn takes forever and you have no way of actaully seeing what the ai is doing other than seeing them move their units on the tactical map and hearing sounds of them firing at your guys. Intead of showing you what the enemy just did like by zooming in on the map to show you graphically what's going on, you get a text appearing if an enemy killed your guys.
It's not well implemented.
