[QUOTE="barsoomcore, post: 444797, member: 812"] Revised Combat rules. Notable changes: Added further text to be clear on threat ranges of zero. Removed the "automatic charge" rule and references to shield bonus, Repair skill and Regain Control stunt. Noted that vehicles only are immune to subdual damage. Changed reference in "Attack an Object" to [i]component[/i] rather than [i]feature[/i] -- I do see the need. We are now talking only about Vessel Components of the sort that BlackJaw has defined. So Component means something very specific. Added note that only Components which possess a hit point value can be targetted. The ramming attack rules now state that the ramming pilot makes a Piloting check against the target vessel's [i]touch[/i] AC. Here ya are: [size=4]Chapter 3 Vessel Combat[/size] Of course, not everything up in the sky is as peaceful as it looks from the ground. And adventurers being the argumentative sorts that they are, there can be no doubt that sooner or later, and most likely sooner, they will end up striving mightily either to defeat some terrible foe, or escape a cruel trick fate had in store. At its core, vessel combat is just like character combat. Some of the differences have already been noted above: the concept of facing, the fact that vehicles cannot run or take a double move, altitude and so on.
