Thundercade
Thundercade, also known as Twin Formation and 特殊部隊UAG", is a vertically scrolling shooter developed by SETA and released as an arcade game in 1987. A version for the Nintendo Entertainment System from American Sammy was released in 1989.
The original arcade flyer establishes that despite a 199X treaty eliminating all nuclear weapons, a certain northerly nation was suspected of developing such weapons in secret. Therefore, the United States of America military sends in the U.A.G. elite unit consisting of an armed motorcyclist and a support bomber to quell the threat. The American NES version's manual describes a slightly different story, casting players as a part of Operation Thundercade, a special forces operation battling against the nuclear threat of the Atomic Age Terrorist Organization of Miracali.
