My campaign is going to be taking my PCs to some hostile environments. What type of skill roll would be recommended for things like:

1) Movement/Action in Space walks or zero-g environments

2) Movement/Action in Enviro-Suit-only environments (zero-atmosphere, toxic atmosphere, radiated or hot environments)

Right now I am thinking either Coordination or Piloting: Space for 1) and Survival or Resilience for 2). However, none of these are perfect fits.

Thoughts? I want to give them a variety of avenues for success as a great deal of time and sessions will be in these situations.

Coordination without some kind of suit EVA propulsion, or Pilot-Planet with I think are perfect.

If the suit isn't providing protection enough Resilience fits imo.

On reflection I'd probably allow Athletics for enduring the harsh environment as well, byproduct of all the strength and endurance training from Athletics.

The first is definitely Coordination in my games. The second would be the same skill it would be without the suit, the conditions just apply Setback.
