Hostility Ultimate Force(UF)2 : 2112 Cooperation - Original Producer of the series: 3DBBQ

————————————————————————————————————————

The story takes place in a universe similar to ours, where the human beings on Earth have made great technological leaps and are about to reach "stellar civilization", and interstellar travel with neighboring planets is no longer a difficult task. But the Earth is in a serious energy catastrophe, with uneven energy distribution and growing disparity between the rich and the poor.

In the past, there was a powerful heroic organization that maintained peace on Earth, but after a fierce battle with a huge evil biological research institute, both disappeared. But new evil forces are emerging in an endless stream, and small street organizations are beginning to emerge around the world at this time, contributing their own meager strength to continue the hero's duty. "Maximum Chaser" is one of them.

You will play two members of the "Maximum Chaser": Kai (Member Num: 10) and Lily (Member Num: 01), and fight against an evil security company A.A.S.S. .

The game is designed for single-player play, which means you need to control the characters on both screens at the same time. As the game progresses, the shooting method will also change. At this time, you will need to judge which side of the screen you should focus more on. Don't worry, it won't be difficult. Of course, you can also take on two-player challenges with your friends. This game does not support remote network connection, so you can only work together locally with your friends sitting in front of the same computer.
