A port of an obscure Taito arcade game, 5200 Space Dungeon marries the intense action of Robotron with the adventuring of games such as Venture. Requiring two-fisted skills, Space Dungeon uses twin joysticks to control the round craft (one for movement, one for 8-way firing) and to blast aliens while grabbing treasure in a series of 99 levels. Each level is composed of a grid of 6x6 rectangular rooms with randomly placed doors, treasure, and foes. A detailed overhead map and a 'collect bonus' directional aid assist you to help keep your bearings.
Control Issues -- the 5200 controllers' looseness and lack of responsiveness make the game harder than it needs to be, but certainly do not ruin the fun. Space Dungeon would be great with twin digital, tight sticks. Still, you'll need to invent some way to hold your controllers together, if you don't own the original pack-in plastic brace. Personally, I grabbed a rectangular box (which was a replacement ballast box for my basement's overhead lights), and with some scissors, a utility knife, and duct tape, I now have a nice functional homemade brace. Once again, duct tape solves the world's problems!
