Very hypnotic, fast-paced, quite intense, just the way I like it. One of the most stunning vector-graphical titles to this date, using color and pseudo-3D playfield to add depth; a great fit for a shooter involving enemies crawling up a corridor. The SkillStep system is also a neat way of rewarding returning and skilled players heading back into the game.

Definitely best to play with a rotary knob though, as originally intended, for the best accuracy.
