19XX runs on the CPS-2 arcade hardware. Easy to learn but hard to master. It will take practice when it comes down to the heavy fire that blazes across the screen, learn to master ways around the incoming fire. Gamers will find that the game really isnt all that hard to figure out and play with. The stages have been revamped from the previous game to give a fuller and richer look that include explosion fires and cloud shadows on the islands far below! Special effects are limited to the planes exploding and even that really isn't much of a leap from the first title, so be prepared to see more of the same but with better color.
