So I'm about to start running a Pathfinder-ized version of the Star Wars RPG but came up with an entirely different setting in the process (that will likely be used in future campaigns). The idea is a Sci-Fi game run with the Pathfinder classes. What I have so far is that Advanced Firearms would be readily available, Knowledge (planes) would function as knowledge of outer space and things in relations to planets that the other knowledges could not cover as well as it's identification of outsiders, and outsiders would mostly live in outer space (likely in some supernatural occuring area associated with their alignment) and gain the ability to survive in vacuum.
What I'm wondering is if anyone has expanded on the advanced firearms for more modern weapons? I'm assuming all I'd really need to change is the amount of ammunition the weapon can carry and perhaps give some of the automatic weapons the ability to fire multiple rounds with a -2 penalty (in addition to rapid shot). I was also thinking about making a feat that allowed a Disable Device check to be made against a construct in order to cause damage or a malfunction. If anyone could give some insight on those I'd appreciate it. Thanks.
This is also what I have as sort of the "droid" or robot race, I haven't come up with a name yet though so I'm going to use Robot for my description.
Construct (Living Construct)
+2 to any one ability score: Robots gain a +2 bonus to one ability score chosen at creation to represent their varied nature.
Small, Medium, or Large: Unlike most races, Robots are created by talented craftsmen and must therefore choose a size category at character creation. A small Robot gains a -2 Strength and +2 Dexterity (in addition to it's +2 to any one ability score) as well as a +1 size bonus to their AC, a +1 size bonus on attack rolls, a -1 penalty to their Combat Maneuver Bonus and Combat Maneuver Defense, and a +4 bonus on Stealth checks. A Medium Robot has no bonuses or penalties due to it's size. A large Robot gains a +2 Strength and -2 Dexterity (in addition to it's +2 to any one ability score) as well as a -1 penalty to their AC, a -1 penalty on attack rolls, a +1 size bonus to their Combat Maneuver Bonus and Combat Maneuver Defense, and a -4 penalty on Stealth checks. Finally, a Robot may not have more than a +2 bonus to any one ability score but may use their +2 to any one ability score to cancel out a penalty gained through their size.
Slow and Steady: Robots have a base speed of 20 feet, but their speed is never modified by armor or encumbrance.
Composite Plating: Robots come with a composite plating that functions as a chain shirt in all ways. This plating is not natural armor and does not stack with other effects that give an armor bonus (other than natural armor). This composite plating occupies the same space on the body as a suit of armor or a robe, and thus a robot cannot wear armor or magic robes. However, a Robot can be enchanted just as armor can be. The character must be present for the entire time it takes to enchant him. A Robot may improve it's composite plating by going to a craftsmen and paying the cost of a different type of armor to have plating that functions as that armor applied. This takes an hour per 100gp in the price during which the Robot must be present.
Light Fortification: Robots receive a +4 to their AC against critical hit confirmation rolls.
Living Construct: If you haven't figured it out yet I've pretty much just modified Warforged sleightly, this functions the same way a Warforged does from 3.5.
Natural Attack: Robots possess a natural slam attack that deals 1d3 points of damage plus strength modifier on a successful hit if small, 1d4 plus strength modifier on a successful hit if medium, and 1d6 plus strength modifier on a successful hit if large.
Check your FLGS for any copies they may have of Dragonstar. It is a D20 fantasy game set in an advanced tech space setting. While it is 3.0 it can easily be used in Pathfinder for weapons and armor and tech purposes.
Was a neat concept that too few people every saw.
why not make it have the robot subtype?
For the droid, why not use the Advanced Race Guide as an example and let players create their own unique character?
I don't have the Advanced Race Guide.
Veil of Truth: Space Opera Rules and Setting seems to be a decent start. It is a little sparse, but if you look at it as conversions for a SciFi setting, then it is pretty good.
