Fortified Zone
Game Boy · 1991
About this game
A male and a female commando named Masato Kanzaki & Mizuki Makimura have been sent to the jungle on a mission.
That mission, should they choose to accept it, is to destroy an enemy base and everyone in it.

Stealth is required, since brute force will only lead to their capture.
On their four-stage mission, Masato and Mizuki will encounter a host of mercenaries, soldiers, robots, and other enemies bent on cutting down the two commandos in their tracks and stopping them from destroying the heart of the Fortified Zone.
It's up to the player to find out if their mission succeeds or fails.
You are able to switch between the two characters at any time.
Both characters have advantages and weaknesses - Masato can use special weapons while Mizuki can jump over obstacles.
About Game Boy
The original Game Boy (1989) proved that handheld gaming didn't need cutting-edge graphics to succeed — its monochrome screen and legendary battery life, combined with Tetris as a pack-in, made it a cultural phenomenon. Game Boy cartridges are famously durable, so this remains one of the more accessible retro platforms to collect, though translucent color variants and complete-in-box copies with the original brick-sized manual add real value for condition-focused collectors.
Gamevaro tracks Fortified Zone for Game Boy with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Fortified Zone to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This GB release dates back to 1991.

Market insights
Rarity & condition
Fortified Zone has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
