Gunhed is a classic vertically-scrolling. progressive-weapons shooter released for the PC Engine in 1989. It is based on the Toho film of the same name. In North America the game goes by the name of Blazing Lasers.
It was developed by Compile, a company known for its high quality shoot ’em ups in Japan, and published by Hudson Soft.
Gunhed is considered to be one of the best shooters – if not one of THE best games – on the PC Engine, and has also even had professional oxygen thief Kanye West praising it on Twitter (he said that it was his favourite game on the TurboGrafx-16 system (the US name for the PC Engine and one he borrowed for the title of one of his albums)).
