Defender Arcade (Atari 2600 Novice/B)

I was on a bit of a Defender kick this week, playing it on a variety of systems, and I think Defender Arcade for the Atari 2600 might be my second favorite version; second only to the arcade original. I played it using a Harmony Encore cartridge and an Edladdin Super Twin 78 controller, with the second player joystick and buttons giving me quick and easy access to the hyperspace and bomb controls. =)
