You have purposefully been captured in order to infiltrate Group 66. The group has documents that hold the key to ultimate power and destruction and you must use your secret weapon (a special tank) in order to find and destroy the documents before Group 66 is able to use them for destroying the world. Use the arrow keys to move around. The spacebar is for shooting, the "Ctrl" key is for deploying bombs and "X" is for energy. If the camera needs to be changed, simply hit "shift," and you can view your objectives by pressing "M."
