Blazer

Blazer is a shooter arcade game that uses an isometric perspective. It was released by Namco in 1987 only in Japan, runs on Namco System 1 hardware, and is the first 16-bit game to use such a perspective. It was also the first game from Namco to feature a "legal notice" saying that the game was for use in Japan only.

Introduction
In Blazer, the player must alternate between a tank and a helicopter (and for the final mission, a boat), to destroy enemies both on land and in the air.
