Game Boy Color · 2001
About this game

Each of the eight stages in PROJECT S-11 poses unique challenges, and each setting is more harrowing than the last.
Although you're going it alone in this one, there are four different types of power-ups hidden throughout the game to give the boost you'll need to survive and wipe out the terrifying extra-terrestrials.
You'll benefit from a complete statistical readout that adorns the right side of your screen, keeping you abreast of all necessary information: your score, your ship's armor level, and the number of bombs you have stored up for combat.
The game's fast-paced action looks excellent in full color, and the intensity of it will have you breaking a sweat before you're through the first level.
Those aliens had better look out with you at the controls, Earth stands a fighting chance.
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 Project S-11 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 Project S-11 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 2001.

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.
