Moon gladiatorial battle arena, gravity is lower than earths obviously and this effects everything, projectiles can curve upwards or they tumble and move randomly, characters can charge but wont stop until they hit a wall, but the player may tap a button to try and skid to a halt. Weapons float and swing around the battlefield, so players can shoot them into other players or deflect weapons into others, or swap on the fly and also means players can carry much larger heavy powered weapons
Future where battles of old are recreated in new ways and televised, and with new technology the weapon range is wider, audiences can watch from earth and there is no risk for the combatants as they can be revived in the combat, they enter pods at the start of the battle and are cloned with their consciousness in the new body, if the body is destroyed they have their consciousness placed in another clone. Word is there is also illegal battles where the combatants are not cloned... story could follow a gladiator who gets pulled into the death games
