House Rules

These are the standing House Rules, most lifted from BSG: Escortstar Meleager. The Italics is commentary by either Kyris (all thanks to him for working out most of these rules in the aforementioned game), or by me. Any additional House Rules you would like to have in effect, please post in the Application OOC, and, if a majority of your fellow Applicants (once we have 5 or more) agree with the proposed House Rule, I will seriously consider applying it.

Control RollsReference Page 151 of the BSG Core Rulebook.

Control Rolls are perhaps the most contested rule in the book, and with good reason. They don't seem to work all that great as written. I've opted to take an approach I found on CS|RPG.

Control Roll Part 1 - Strength: The book states that a character needs a minimum Strength equal to that of his ship to pilot it without a Control Roll.

The Problem: I've watched a a lot of BSG and have yet to locate the 500 pound Russian weightlifter who functions as Galactica's helmsman. Because it currently requires Strength 12d+d4 to fly the ship without a control roll. Personally, I wouldn't apply these rules to Spacecraft Scale craft, only to Planetcraft, but the Rules As Written (RAW) don't work well for planetcraft in my opinion, either.

The Fix: Instead of basing thrust on Strength, base it on Speed-2 rounded up to the nearest die type. Galactica has a Speed of 5. Subtracting 2 yields 3. Rounding up yields d4. Anyone with Strength d4 or above can fly Galactica without a control roll. A Viper has Speed 8, subtract 2 yields d6. Strength d6 is needed to control a Viper. A Cylon Raider has Speed 9. Subtracting 2 yields 7. Rounding up yields d8. Strength d8 is needed to control a Raider.

Control Roll Part 2 - Alertness: The book states that a character's Alertness must equal a vehicle's Agility in order to fly that vehicle without a Control Roll.

The Problem: Of the seven characters written in the BSG whose prime occupation is Viper Pilot, only two (Starbuck and Flat Top) have the Attributes required to fly the thing without Control rolls.

The Fix: Subtract 2 from a vehicle's Agility die code (for a Viper, that's a d8). Both Alertness and Agility must be at least Agility-2 rounded up to fly the vehicle without control rolls. If either is less, a Control Roll is made using the lesser attribute.

So, somebody wanting to pull off Starbuck's stunt of piloting a Cylon Raider (Agility d12, Speed 9) would need a minimum Strength d8 (Speed-2 rounded up yields d8) and both Agility and Alertness of d10 (Agility d12-2 = minimum Agility and Alertness of pilot). Starbuck, fortunately, has Agility d10, Strength d8, and Alertness d10.
Ship Life PointsA Spacecraft Scale Ships' Life Points are now calculated as Strength+Vitality+Willpower multiplied by their Wound Armour. This gives Galactica a final Life Points 192.

Planetcraft Scale vehicles/strikecraft are calculated as straight Strength+Vitality+Willpower.
This rule edit came mainly because I discovered how damn delicate ships are in ship to ship combat under the Cortex rules. This is especially true when you are firing multiple batteries at a single target, which is hardly unusual for any ship but the very smallest. It also gives a much larger range of LP values, giving ships a real difference in vulnerability. For vehicles (especially strikecraft like Vipers, Raptors, and Raiders), this cover the fact that they could be hit by hostile weapons fire and still fly, but any prolonged source of damage (such as you see in the series, when the Viper pilots are putting 3-second-long bursts into Raiders or Raiders are returning the 'favor') and they tend to blow up.
Ships and Critical DamageWhen a Spacecraft reaches Half Life Points or has 60 Life Points remaining, whichever is less, it can begin to suffer Critical Damage. Each time a ship takes damage after it has dropped below this mark, roll a D10 and add the Weapon Damage. Compare this result to the Battle Damage Table (on page 270 of the Colonial Warbook IIe), and then apply the effects listed.

Example: Galactica reaches only 59 LPs due to its continued engagement with a pair of Basetars. It is then hit with an attack that does 8 Samage after Armour is applied. The GM rolls a d10, resulting in a 7, adds the 8, then looks at the table. Under 15 s/he finds the "Weapons Damaged" Trait. He determines that Galactica's main battery (its Capital Railgun Turrets) are damaged, and cannot be used until they are repaired. (Or frantically jury-rigged by PCs.)
Weapons Barrages/Linking WeaponsIdentical ship's weapons can be combined in batteries of between two and eight. These can be fired as one weapon at a single target. Each weapon after the first gives a +1 to the attack roll, to a maximum of +6 (note that is not die-steps). A successful attack by a battery gives the weapon a +1 Die Step in damage, or +2 Die Step in damage for a full 8-weapon battery.

Example: F.S. Daring combines all six of its railguns into a single battery. They get a +5 to hit, and do Damage D12+D2.
This rule edit was because of the ridiculous number of weapons each ship mounts, and not wanting to be rolling twenty attacks per ship every turn. This is not one of mine, but I'm putting it here because it has an affect on later rulings.
This means that Viper Mark VII's with their three cannon, get a +2 to the attack roll and a +1 Die step in Damage.
Point Defense SystemsAll Colonial Fleet ships (and certain civilian vessels) mount batteries/networks/arrays of specialized weaponry (usually smaller-bore, rapid-firing--often "Vulcan"-style--guns; rapidly-reloading arrays of small, fast, accurate missiles have been used, though) for shooting down incoming missiles and hostile small craft. Electronic Counter-Measures (jamming, decoys, flares, chaff, et cetera) also uses these rules, but effect missiles only. The Cylons seem to believe physical Point Defense is something that happens for other people. (And to them.) The "flak barrage" of a Battlestar (but not any lesser vessel) also degrades incoming direct fire to a degree.

When a missile barrage enters the range of the Point Defense System(s), the GM/Tactical Officer/Defense Officer should roll the Point Defences' Die-rating. This gives the percentage of missiles destroyed by the Point Defence System(s). The rest of the missiles continue to advance one Range-rating closer, or, if they are at Skirmish-range, impact. Against small craft, the Point Defense Systems Die should be rolled every turn those small craft stay within the range of a ship's PD system(s). They are not destroyed immediately and instead take Damage equal to the PD Systems' Die. Ships with (a) Point Defense System(s) with Capital-range (or--theoretically--greater) can attempt to intercept all missiles passing within its PD range (even if they are not aimed at that ship); this is called "Area Defense" and incurs a two Die-step penalty to the Point Defense System Die-rating. (Which is why, normally, only Battlestars do this; not to mention, few other Colonial ships besides a Battlestar even have a Capital-range PDS. Of course, Battlestars also have plenty of main gun batteries to thicken up their Point Defense. And strikecraft. And "Wild Weasel" Raptors.)

Point Defense is also degraded (minus 1 Die-step) versus missiles only for each additional vessel launching missiles that are being engaged by a given vessel's PD System(s).

Addendum: A Point defence network may be enhanced by the ships main batteries firing explosive or flak rounds. This enhancement comes at a +1 Die-step bonus per battery (+2 Die-steps for a full 8-weapon battery) of direct-fire weapons (usually railguns) added to the defence. When a Battlestar does this, it subtracts 1 Die-step from incoming direct-fire weapons (usually railguns) per battery added to Point Defense. All that "flak" would prematurely detonate explosive shells and impart enough energy to some incoming solid shells to casue them to miss. It should also be noted that "flak barrages", unlike normal Point Defense, do not distinguish between firendly and hostile strikcraft/weapons fire; all strikecraft and weapons fire "caught in the solution" of a "flak barrage" are subject to damage/destruction equally.

Example 1: A swarm of 6 missiles heads for F.S. Daring. The gunnery officer rolls the PD network's die (D8) and gets a 6. 60% of the incoming missiles are destroyed, leaving 2 to impact the ship's hull.

Example 2: The Tactical Officer aboard F.S. Daring decides there are too many incoming missiles for the standard PD system to handle, and so adds the two main (six-turret) batteries to it. This turns the Daring's PD network from a D8 system into a D12 system.

Example 3: Galactica, covering the civilian ships Jumping out of Ragnar Anchorage, places itself between the Basestars and the Jumping civilian ships. Commander Adama, knowing that those civilian vessels will be turned inside out by the heavy barrage of missiles likely to come from the modern Basestars, orders a "full flak barrage" (all main gun Batteries that bear added to Point Pefense) and the PDS set to "Area Defense". (Because Adama in the show faced Galactica's dorsal side to the Basestars, literally "covering" the civilian vessels' Jump point with the Battlestar, only a single 8-gun battery--the eight railguns mounted dorsally--bore on the incoming fire. Because I'm ignoring such things in the interests of both the party and not giving myself headaches, here BS 75 uses all three 8-gun batteries to thicken her point defenses. The Cylons should feel lucky they weren't facing the pre-refit Galactica with her frakking 52 railguns, or 7 batteries.) Galactica thus rolls (d12+d2 minus 2 Die-steps=d10 for Area Defense, plus 6 Die-steps=d12+d10) d12+d10 for Area Point Defense. The Cylons, for dog-piling with 4 Basestars, cause a degradation of minus-3 Die-steps to the Point Defense. In the end, Galactica rolls d12+d4, getting a 10 during the first turn of combat. The Cylons' missiles are all destroyed, as are most of their "Sparrows" in the firing solution (since Galactica still rolls d12+d10 vs. strikecraft with her PD). Next round, Galactica's PD system is starting to feel the heat, and she only rolls an 8 on her PD die...thus getting hit by the Cylon missiles. And so on....
Point defence networks... who knows how Margaret Weiss expected those to be handled. This makes it very very simple if you are focusing on the defending ships crew. There are another set of rules in the warbook, which are great if you are focusing on pilots. (Thanks Limerickot)
MissilesA missile barrage can be badly affected by PD, strikecraft shooting them down, and ECM-strikcraft playing "Wild Weasel"...yet some missiles can still impact. So how do you model the different number of missiles impacting on a ship while still using the Battery rules? If the number of missiles impacting from a single barrage or battery is over 50%, add 1 Die-step to Damage. If the number is under 50% but above 1, keep the Damage as normal. If the number of missiles impacting is 1, then reduce Damage by 1 Die step. If the number of missiles impacting is 0, then 0 Damage.

Basic Damage is worked out as the Attack Roll vs. the PD roll. This does mean Basic Damage can work out as zero, but the actual damage should still be rolled.

Example 1: 10% of a 6 missile, Damage d10, barrage is destroyed, leaving 5 missiles to impact on the enemy ship. As this is over 50% remaining, the Damage is stepped up to D12.

Example 2: The missiles' Attack Roll was 4, and the PD roll was 8, destroying 80% of the missiles. However, this still leaves 1 of the missiles to impact. It will do no Basic Damage, but it will do it's normal damage die (though stepped down for their only being 1 impacting).
Missiles are hard. They should work very differently compared to main armaments, but the book does little to show these differences. This is what these rules are for. Also, I don't let ships dodge missiles, or even use innate defence. (Note, subcraft--especially strikecraft--can attempt to dodge missiles. They can also shoot the damn things down.) The only options are ECM and Point Defence... Good luck. (Oh, and your Armor--plus frantic IC prayer--when all else fails.) However, because of missiles' vulnerability to various defensive measures (and because the Colonials learned early in the First Cylon War "There is Never Too Much Point Defense, Just Too Much to Fit on This Ship"), the Colonial survivors of the Cylon Attack have a chance at surviving.


Missile Time-to-Impact
Launched At Range: Time to Impact

Long DRADIS-range: 3 turns to impact
Short DRADIS-range: 2 turn to impacts
Capital-range: 1 turn to impact
Skirmish-range: Immediate impact
Yeah, not much explanation here. There were no rules for this in the book, and given that Long DRADIS-range is supposed to be a couple thousand kilometers, I thought these should really appear.
Nuclear WarheadsIn atmosphere and in the blast radius without hardened shelter..."Game over, man, Game Over!"

When used against a surface target from orbit..."It's the only way to be sure."
Now that I'm done with classic sci-fi movie quotes...


In space, ship-to-ship combat, they are the preferred method of quickly stripping enemy capital ships of their escorts and rapidly destroying hostile capital ships in "Alpha Strikes". Nuclear warheads (in general, but especially tylium-enhanced warheads) cannot be utilized with direct-fire weapons and must be delivered by missiles...making them vulnerable to point defense. Cylons primarily utilize tylium-based kiloton-range "tactical" warheads for both strikecraft and capital missile warheads, only deploying megaton-range "strategic" warheads only for high-priority ground bombardments. The CDF, in comparison, uses fusion warheads of 3-5 Kilotons for strikecraft missiles, 50-100 Kilotons for Escortstar missiles, 100-200 Kilotons on Gunstar missiles, and anything 10 Megaton yield and larger (not usually over 25 MT) to arm Battlestars. Due to the threat of Nukes and abundance of Kiloton-range warheads on both sides, both Battlestars and Basestars are built to "shake off" the effects of being hit by "tactical" nukes.

Nuclear missiles that hit their target ALWAYS do their rolled damage in BOTH STUN and WOUND at SPACECRAFT-scale. Basic Damage still applies. Additionally, nuclear missiles with yields in kilotons (carried by everything except Battlestars, Basestars, and Warstars) double their damage total against all targets Except Battlestars, Basestars, and Warstars. Nuclear missiles with yields in the megatons (Battlestar, Basestar, and Warstar nukes) quadruple their damage total against EVERYTHING.
Nuclear weapons are awesomely terrifying and/or horrifyingly inspiring tools, most often used in fiction (understandably) as weapons, and so far only deployed in real life as will-breaking weapons (twice) and used as political tools (quite frequently; there's good reasons why the first five countries with nukes are the five permanent members of the U.N. Security Council). That Galactica "shook off" a "small" nuke (there is only so much Boom! you can stick into a fighter missile, even with Cylon tech) missing most of her armor, coming away with light damage and no radiation hazard...that just presses home how freakishly tough a Battlestar is. But my point is the words "Radiological Alarm" IC should induce serious ass-pucker...and I think these rules do that. Keep in mind: the Basestars and Warstars attacking the Colonies (aside from 4 Basestars on a special mission) are carrying only nukes...and most of the Raiders are also carrying a couple nukes...
