Wall Defender (thing)

The only thing special 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 is a single screen game. You are positioned in the center of a small maze. Monsters from the outside attempt to break into your maze, and you have to defend yourself from them. The concept has been done much better in several other 2600 games.

This game isn't fun. But it is valuable due to its rarity. Expect to pay over $100 for a copy of this, without the box or manual.
