Alien Abduction II follows the never released Alien Abduction game where you must abduct people for probing while avoiding the ever pesky MIB agents. Using your tractor beam, you can pick up a variety of objects, and even drop them on enemies to keep them from escaping or firing at you.
If you have a Bagunk account, you can link your score to your account.
You can cheat and jump to a level by holding shift+[level #] where the level # is a number key cooresponding to the level you want to jump to. Cheating, however, forfeits your ability to submit a score.
