yah it not alienbusters way to many colors going on there, the game was mostly green and black wireframe and no console like alienbuster. battlezone
by atari look might close to, but battlezone is not tape or is there "enhanced/clone" of it that was? As for the opera song it could played that song when you where loading the game in the tape deck or it could just played that song when it was put in a cassette walkmen, or both but I do know there was opera song with it cause I remember it I will check out that site and see if any of the listed games look like it if there are
photos there
Its not death zone, dimension x, combat zone tank attack or super tank attack, still cant find a screen shot tank commander in game though, while going threw there I did see tapper se which I did have too. I willing to bet if I can find out where my uncle put all my atari and nes games all this stuff will be in there, except for that tape game
Orc Attack look like the other game I was talking about.
