Gumshoe (NES)

Very weird first party title, that released alongside the Nintendo Entertainment System. 
It was made by Nintendo themselves, which shows, because there's a good idea on display here; it's a platformer, that you play with the NES Zapper. Problem is, it's not very fun. 
Still, it's considered a classic because it was part of the initial "black box-series" of launch titles. 

Please note you need an NES Zapper to play this, and a CRT TV. 

Condition: Good. French version but game is in english.
