Dark Arena

Everything seemed just dandy in the United Arms Organization. The best crop of young soldiers ever had just completed its training, and it seemed the time was ripe to challenge some genetically-engineered sparring partners. Unfortunately, the creations developed minds of their own, killed most of the human soldiers, and began to develop further plans. As the only soldier to survive the massacre, it's up to you to devise some means of not only escaping the area alive, but taking out all of the enemies on your way home.
