Gravity

If your game takes place in a futuristic setting, characters might find themselves in a situation where they are away from an artificial gravity device, floating in open space, or walking in the crushing gravity of a supergiant planet.

  Normal gravity is the default and does not affect any skill checks, attacks, or the like. However, sometimes the characters end up in an environment without normal gravity: a starship with artificial gravity that has been disrupted by damage (or, depending on the setting, a starship without artificial gravity at all) or a large planet with a higher-than-normal gravitational pull, for instance.

  Stronger-than-normal gravity adds up to b b b to any Brawn-based skill checks (except Resilience checks) and to Coordination skill checks, depending on how strong the gravity is. Weaker-than-normal gravity adds up to b b b to any Brawn-based skill checks (except Resilience checks) and Coordination skill checks, depending on how weak the gravity is.

  Zero gravity, on the other hand, does not grant any b or b to skill checks, because moving in zero gravity is completely different from moving in a gravity field. Characters can move in three dimensions in zero gravity, but they count all movement as movement through difficult terrain, due to having to constantly grab handholds, evaluate angles, and so forth.

  A character’s encumbrance threshold does not change due to different gravity, and items still maintain their usual encumbrance. This is because an item’s weight may change, but its size and mass (and therefore its inertia) do not. Those pesky details can prove an unpleasant surprise to inexperienced spacers who attempt to shift something large and heavy while in zero gravity.
