Defender is a 1983 SHUMP released on the ColecoVision. Mark said that if you hear any static in the background, it's due to the VCR. He said it was pretty much the best that you'd find on an 1980's system. He notes the smart bomb. He said the Atari 2600 Version was very different. He also said it's easier than the arcade version or Atari version. He said it's still fun today and recommends it.
