Shark Attack was first released by Milton Bradley back in 1988. I was really into board games throughout the 1980s and well into the 1990s and this toy was a must have for me at the time. Unfortunately it was not as exciting as it looked and lost its luster as I got older, but the constantly moving shark made for a great chamber of doom when playing with GI Joe action figures.
No, Low-Light, I expect you to die! Unleash the shark! Cobra!!!!!!
Shark Attack is still made today, but is no longer a Milton Bradley game, but is instead being released by Patch products. I am not sure who they are, but the game looks pretty similar to the original.
