Just like Xevious you have to pay just as much attention to ground forces as your airborne foes. In order to fight the big bad you have to take out ground shield generators among other things. There is plenty of challenge to be found and your on screen radar shows you where enemies are coming. An on screen arrow guides you toward your destination. The only bad thing about the freedom the game gives you so far is the fact that enemies are everywhere and even if you don’t see them they can fire on you and kill you without your ever have seeing them.
