What, you thought recreational physical activities would die out in the far future?
Grav Ball: A sport popularized in the Epsilon Eridani system among the orbital population. Played along a 200-meter strip of a Habitat-1 style sphere habitat (500m diameter), centered on the equator. The effective gravity diminishes as one kicks or throws a spherical ball towards the goals on either side but coriolis effects produce some interesting spins that can thrown the ball in unexpected directions to the unpracticed. Popular legend claims the sport was developed by an eccentric EDI exec and attributes the very existence of rotational habitats in the system to the sport. Though many historians believe spheres were constructed to prevent skeletomuscular degeneration in orbital workers and Grav Ball was invented afterwards to encourage workers to spend time in the high-G sectors.
Meteor: A game specifically designed for parahumans with spacer mods, while players are suited they tend to wear light suits not pressurized below the transparent-aluminum helmet for mobility. The field of play is a cube of space half a kilometer to a side, with 20-meter goal nets on two opposing sides. The teams float in the space without EVA units, using each other or “debris” (originally scattered rocks, now constructs with jutting poles or lines) to maneuver and attempt to fling a 20-centimeter ball towards the opposing goal. Players may use either their natural appendages or a telescoping 10-meter pole with a net on the end to grab and throw the ball. For visibility’s sake both the ball and the players’ spacesuits are covered in blinking lights, the ball changing to the colors of the team that last touched it. The borders are patrolled by drones with cold thrusters that automatically retrieve balls, debris, or players that leave the playing zone, at the end of the two-hour game they also pick up any players who found themselves dead in the water. Every thirty minutes the game breaks for players to change out their oxygen bottles, delivered by the drones to their positions or vectors. It’s not uncommon for players to spend multiple quarters in the same position until something impacts them.
BloodClaw: Many parahuman species have claws, sharp teeth, or other natural weapons. Historically, many competitive martial artists have been required to cover these in order to limit the chances of accidentally killing a fighter, but the spread of medical microbots changed that. When House Rektol made Outworlder clients fashionable on the world of Janssen literal bloodsports finally crept up from the underground to become an official spectator sport. Microbots can seal most superficial wounds in minutes, and if their host comes close to death they can force the brain into a state of stasis until they can be resuscitated, with brain scans and external memory up to 50% brain damage is (legally) survivable. Replacement limbs and organs can be bioprinted in hours. With that in mind the practical objections to extremely violent sports were sidestepped.
In original Janssen rules BloodClaw athletes are limited to their phenotype’s natural weaponry, no augments, fighters score points by drawing blood from their opponent and the match ends after five minutes or when one fighter loses consciousness. Many variants exist, ranging from lightning-fast “first blood” bouts to agonizing mutilation bouts and an “aug league” where fighters try to stick on as many blades and bioware as their bodies can fit.
“Flatline” has yet to breach the mainstream, except in the lawless habitats of Barnard’s Star and similar Tortugas. In this variant of BloodClaw the match only ends when one fighter shows no brain activity. Usually the loser can be resuscitated, but Real Death is not an uncommon occurrence. If the victim of this underground match was sufficiently valuable to their patron they might be cloned, but said clones are prone to existential depression that often goes untreated before they die and are replaced by another iteration.
