RetroGrade #30: ATARI 2600: Bomb, Konami, Answer, MB 

Pooyan and Strategy X were both Konami arcade games. I have no idea about Marine Wars.

Ikari Warriors was an SNK arcade game.

Spitfire attack is very underrated. It's an A for me

I think saying, "Bomb did not know what they were doing other than shooting four directions in space" is unfair. In Assault you can only shoot in three directions.

Fun thx
