The game is full of action, even the story is told on a comic style and it tackles places and animals. Although it seems kinda advance to kids, the game play levels up with them so your child will have no troubles going through the game, in order for your child to unlock more aliens, the actually need to finish the whole game or finish levels, at first this is confusing, but as you play the game it actually makes sense, and that's to play the game all over again. If you want full action with a twist of science and biology. I recommend getting this game game. Buy it and believe.
