Uncharted Worlds has a Move called “Shields Up”. It’s a pretty simple move to resist damage. But ships in The Expanse don’t have shields. So what the heck do we do?
PDCs to max!
Attempt to shoot down incoming torpedoes; roll 2d6.
On a 10+, you eliminate the most dangerous torpedo attack pending.
On a 7-9, you defeat the incoming attack but the next attack takes -1 (include any previous negatives).
On a 6-, the PDCs have failed to protect and the torpedo hits.
But what about railguns?
Roll, pitch, and move along the thrust vector; roll 2d6
On a 10+, you dodge the incoming railgun attack. Yay!
On a 7-9, take half damage.
On a 6-, you take full damage.
OK not exciting, but that’s about all they do in the show.
