Hexsider

In a futuristic vision of the 21th century, mankind's most demanding and dangerous tasks are carried out by modular, adaptable robots called Hexsiders. But dependence has its pitfalls: a rebelling faction of robots has taken down the defense command center by sabotaging its main computer - deactivating every robot within, but keeping all the automatic security systems engaged. Outside the compound, only a small detachment of six Hexsiders remains. Control can be freely transferred from robot to robot.
