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 Commodore 64
Released in 1982, the Commodore 64 is the best-selling home computer model of all time, with an enormous software library spanning games, productivity tools, and everything in between. C64 game collecting centers on cassette tapes and floppy disks in their original packaging — physical media that's inherently fragile, so complete, working copies from the era are increasingly prized by retro computing collectors.
Gamevaro tracks Silk Worm for Commodore 64 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 Silk Worm 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 C64 release dates back to 1988.

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.
