Park Brothers developed this conversion of Konami‘s classic arcade game, Super Cobra, and released it on Atari 8-bit home computers in 1983.
Graphically it is very good, with nicely-defined backgrounds and sprites, and the colour cycling that defines its arcade parent.
Gameplay-wise it is solid too – balancing challenge versus playability nicely, and having reasonably forgiving collision detection.
