I got this one on level 5 just to suggest a level to try to get this on. Make sure you have at least 2 lives remaining before going for this!
An enemy that shoots down the tractor beam to abduct you will eventually appear. Get into the path of the beam and don't shoot or else you may destroy it, which will release you. You'll see the enemy that abducted you at the top of the level with a red Fighter over it, shoot it. Once you kill the enemy and the Fighter the achievement will unlock.
If you think this solution can be improved tell me by commenting, and if you dislike please tell me why. Thanks!
