Hello

i don't find Balls of steel on GOG, i think it's retired like Duke Nukem

(i have payed this game 30 novembre 2015, and i don't find it on gog)

great thanks for your a future answer.

(excuse me for my bad english, i study)

I'm sorry nobody responded to you sooner, but it was removed from the catalog due to its connection to Duke.

Since you've purchased it, it will still be downloadable from your library.

If you can't find it in your library, contact support.
