The first player would play as a helicopter, but if a second player joins the game, they would play as a jeep.
Both players would have to protect each other as well as themselves.
After a certain number of kills, a "goose" helicopter would form on the screen.
If the players managed to destroy it they would get a weapon's powerup.
This would go on throughout the entire game, and a "goose" could appear even during the fight with the end-of-level baddie.
About Sega Genesis
Known as the Mega Drive outside North America, the Sega Genesis (1988/1989) was Sega's most successful console and Sonic the Hedgehog's original home, fueling the "console wars" era against Nintendo's SNES. Genesis cartridge collecting is well-established: common sports and platformer titles are affordable, while sports-license and later-era games with smaller print runs can carry a meaningful premium.
Gamevaro tracks Silkworm for Sega Genesis 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 Silkworm 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 GEN release dates back to 1988.
