All rats/womp rats (except for storyteller and pet womp rat) have been flagged as attackable by ship guns, so that you may hone your ship gunner skill.
A Ship Gun Mastery collection (with server first) has been added to the Badges collection page to track your progress and grant badges and titles for reaching various milestones.
Rats/womp rats killed in this fashion will not drop any loot or harvestable resource.
The ship must be moving above a certain speed threshold for the hit on the rat/womp rat to count. The speed threshold is approximately the same as a character's normal run speed. If you keep shooting at rats/womp rats while below the speed threshold, you will eventually get a system message reminding you of the errors of your ways.
