Expanded Space Rules

This set of variant rules provides a more realistic approximation of some of the stranger phenomena concerning zero gravity and vacuum environments. They're meant to supplement the existing rules, not replace them. You can apply any or all of them to your campaign, as each adds additional challenges and opportunities for memorable moments in space! These rules add additional complications to an already logistically complex environment. Therefore, you should only use these variant rules if you plan on having multiple encounters in space. Make sure the first couple of encounters in zero gravity are simple in execution and trivial in difficulty so players can get used to the additional rules and understand them before you add additional complexities like creatures who use special abilities to exploit the environment.
