Gameplay Let's make no bones about it, the game is retro, and what really matters in a game of this kind is its gameplay. After all, people aren't going to buy it for its graphics or groundbreaking engine, they're going to buy it for the gaming experience. Players shoot their way through tons of grid-levels, controlling a polygonal character with full freedom of movement. At any given time there are increasing multiples of opponents on screen, with little to no slow-down. A basic controller configuration similar to that of the PlayStation version is available, but the real fun comes with the addition of a second controller.
Players walk with the analog stick on one controller and shoot with the analog stick on another.
It sounds odd, but it is absolutely ingenious and replicates the same double-joystick control of the original arcade machine. It allows for so much movement possibility that addiction is inevitable. For example, I sat down to play a few quick rounds before lunch today and by the time I realized it I had progressed through more than 70 levels. I would have continued on, too, had I not been killed off. It's safe to say that the addition of the second controller is one of the most intuitive gameplay enhancements in a long, long time.
