Out Zone (アウトゾーン?) is a 1990 arcade game by Toaplan and distributed in the US by Romstar.
Out Zone is a run and gun, in which the player controls a soldier who must fight his way through seven increasingly difficult levels. At the end of each level a boss must be defeated before the player can progress any further. Taking place in the year 2097, mankind is invaded by an alien race and it is up to cyborg soldiers controlled by the player to destroy the invasion force.
This game was followed up with Fixeight in 1992.
Outzone was manufactured in 1990 by Toaplan and released same year for the Arcades, it’s not an usual shmup with planes but a vertical run & gun shooter that might be annoying because of high difficulty level, restarts from specific checkpoints and the vitality of your hero that dies after one shot. It’s a quite good game but also very short if you know how to approach. There are a lot of multiple enemies to defeat, quite easy & hard bosses and 4 weapons to choose. Standard laser rifle that can be used freely, 3way spread gun with fixed firing position and quite rare flamethrower with yoyo-ball.
