Atari 2600 Game

9 Extremely Rare
The special thing about this game is its rarity. You will probably never see a copy of it outside of Europe. The European copies are also kind of difficult to locate.
This game was an attempt to clone Defender with a few new twists. But the resulting game breaks no new ground, and can't even get close to the playability of Defender.
This game is slightly fun. It is fairly valuable due to its rarity. Expect to pay over $100 for a copy of this, without the box or manual.
