Technology has progressed to the point that air-based nuclear attacks are ineffective, so warfare will be conducted the old-fashioned way: through large-scaled attacks of armored units and infantry.
In this one-player strategy or action game, you'll choose to either control the American or the Chinese military forces, each side comprised of the same eight different unit types.
From the speed and power of a tactical helicopter attack to the all-out brawn of a platoon of tanks, you'll have all the warfare options you'll need to carry out your plan of attack.
In order to complete the game, you'll have to battle your way through 16 different missions that take place all over the world, in such locations as barren snowfields, yawning deserts, and crowded cityscapes.
About Game Boy Color
The Game Boy Color (1998) added a color screen to the original Game Boy formula while remaining backwards compatible with the entire existing cartridge library. Its colorful, semi-transparent cartridge shells make it a visually distinct platform for shelf collectors, and several late-cycle exclusives — released just before the Game Boy Advance took over — are notably harder to find complete today.
Gamevaro tracks Force 21 for Game Boy Color 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 Force 21 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 GBC release dates back to 2000.

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.
