The classic Bitmap Brothers' top-down fighting game boasted a sound track by Bomb the Bass (apparently) and loads of shooting of bad dudes in dodgy graphics which were quite acceptable at its time of release. The plot, as it was, involved this sort of engine thing which needed destroying, otherwise the world would be flooded by, er, chaos. A two-player option, using one machine, and a range of the power-ups and funky weapons make searching the various complexes quite entertaining. But it's the fighting, shooting and destruction of these chaos spawn that make it such a good laugh.
