This was one of the very first true first person shooters in arcades. It has free directional movement, and looking combined. It also has a huge amount of level variety, and boss variety, with different playthroughs having different bosses. One thing that needs minmaxing is which bosses have the fastest cleanest strats. The laser guy seems to be a solid choice for special weapon too.
