Spy vs. Spy for the Sega Master System. Heckel and Jackel -- two sadistic spies; one's black, the other white. Both have the same objective: destroy the opposing spy through any means necessary! Based on the MAD Magazine comic strip of the same name, Spy vs. Spy puts you in the role of either spy, on a mission to escape the embassy, top-secret documents in hand. However, as simple as this may sound, the actual process gets just a tiny bit trickier.
