Speedball is a video game series based on a violent futuristic cyberpunk sport that draws on elements of handball and ice hockey, and rewards violent play as well as goals.

The story is centered around Alan's son Jethro ("Jet") Bradley. Since the film's events, ENCOM has been taken over by a company called Future Control Industries (fCon). After talking with his father who is kidnapped while on the phone with Jet, Jet is digitized by Ma3a, Alan's AI computer system, to aid her against Thorne, an executive from fCon improperly digitized into the computer who is now a virus throughout the system. Jet is mistakenly identified as the source of the corruption and captured by Kernel, the systems security control program.
