There are lurking secrets in this game. Once, I even wished that it would include Bin Laden's but no, just the virtual secrets of ET instead. For the final secret, you need to uncover all the others. In each stage, you have to scan all the five data bank items to get a secret. If you've mastered to finish a game, then you get a bonus, a secret (a deep dark one). This will be tough, but if you wish to select alien Gray as a multi-player avatar, you'll have to outdo the Campaign mode on the hard way.
