Fortified Zone

Fortified Zone, known in Japan as Ikari no Yōsai (怒りの要塞, Ikari no Yōsai, "The Fortress of Fury") is a 1991 video game developed and published by Jaleco for the Game Boy.

Each character has their own strengths and weaknesses: Masato (the male mercenary) uses all the special weapons, but cannot jump.

At the end of each level the player faces a 'boss' character: a cannon installation, a supertank, a dragon, a bulldozer and a large assault vehicle as the final boss.

Super Gamer gave an overall score of 70% stating: "Original shoot-'em-up which is a bit too short to hold anybody in its grasp for long.

"[1] Survival of the Fastest, the debut album of Irish thrash metal band Gama Bomb features the song 'Fortified Zone' based on the game.
