America in the year 2032. You're an ordinary prisoner, and day to day life is a slog. You consent to subject yourself to biological experiments so things might get better, but all is not well. After the next injection, you start to mutate and grow wildly aggressive, then killed everyone who was in the lab and fled. During the escape, you notice that you are gaining strength and can move quickly with great stamina. Soon you are on the wanted list as a dangerous mutant. You need to cut down your opponents and find an antidote before the mutation gets to you as well...
