Hypergolf
Played in specially constructed asteroid fields, the players attempt to negotiation special aluminium-clad iron balls around a stable course of especially (and carefully) positioned asteroids.
Players are not allowed to use targetting systems and have to use skill and judgement to hit the ball round the course, allowing for the microgravity of the interventing rocks.
Special additional hazards are constructed by placing magnetic 'traps' on some of the asteroids to affect ball trajectory deflection, and by placing slow moving dust fields in lagrange points between some rocks.
