Thunderground for Atari 2600
in this game you play as an armored car or something(it looks like a car) at first it looks like it's going to be some kind of boulder dash or dig dug clone but it's not. the goal is to destroy the glowing objects in the squares at the top of the screen while avoiding the tanks or destroying them. this wasn't as bad a game as I expected it to be.
