Many new types of battles. New CO's. More unrealistic combat agaist Black Hole weapons.
Your CO's can now level up and gain abilities. However, your opponents almost never have abilities of their own unless you give it to them. So the abilities are a way to make gamepley easier. Yet, not using them can result in more experience.
The graphics are cooler than ever. The CO Powers haven't changed, but the new Tag Power is an awesome way to play.
Their are more sounds involved. The old CO's still have their music, but thenew CO's have new music that you probably aren't ready for.
This game is definitely worth the money you pay for it. Just keep on playing to get these medals that could get you Sturm if you acquire all 300 of them.
Yet the game is getting farther away from real combat. A real soldier would laugh at it. Then again, it is kind of funny.
