"A particular heir to old classics like Double Dragon and Final Fight."
Iron Fist comes to your PC as a fight game, but a different fight game to what we see nowadays. It is a little "retro" with a look that is right out of the eighties.
Iron Fist`s development gives you a beat `em up with a classic horizontal view, punches and kicks all over the place, and enemies that come at you from all directions. There are plenty of objects to help you (or slow you down, not all are good) in your adventure, but always with doses of humour. It is an heir to old classics like Double Dragon and Final Fight but a little less serious.
