Steve Jackson Games GURPS – Generic Universal RolePlaying System

Like many gamers, I was weaned on science fiction gaming by GDW's Traveller. Even today you still hear people talk about Traveller's "little black books". Thus, when I starting thinking of GMing a GURPS space game, the obvious way to go was to take the Traveller background and combine it with GURPS. This is the result of those efforts: GURPS Traveller!

It is assumed in this article that the reader has access to Traveller rules, GURPS Basic Set, and GURPS Space (However, Space is not strictly necessary). These rules are aimed at "Classic" Traveller and can also be used for MegaTraveller. Traveller rules are used intact for ship generation, ship combat, world generation and world economics. To convert GURPS skills levels to Traveller, for when Traveller material is being used, the formula Traveller Skill=(GURPS Skill-10)/2 is employed.


It is recommended that characters start at 110 points with; 30 points of disadvantages (since Traveller characters tend be less qquirkyn), 5 points of quirks and maximum of 90 points in stats. Suggested starting cash is 2,500 Cr (Credits). The benefits associated with mustering out (including extra starting cash) are bought as advantages (see below). A character point will buy 1/2 starting cash (1,250 Cr).

To retain some of the flavor of Traveller, where most people are an ex-military or ex-merchant something or the other, "careers" are used. This is essentially a grouping of skills into background areas so that what a character has learned matches what he used to be. Careers are not mandatory and there is no "point break" associated with careers. However, some skills are only available to characters using the appropriate careers (see below). They impose some minimal requirements on a character. For characters with backgrounds not covered by the listed careers; a) no career is necessary if no skills with career requirements are used, b) a similar career can be modified or c) the GM can simply look at the character to make sure that the character's background matches the skills he/she has learned.

Each career comes with a list of required skills. A character must take at least 3 required skills from the career. They must have one each at a level of at least 11, 12 and 13. At least 1/4 of all points put into skills must be in required skills. Also, the PC's skill list should be constant with their background, years of service, and specialty (if any) within the profession. Characters may combine careers provided they meet all requirements. Careers are listed at the end of the Article.


For use in GURPS, add one to Rank levels in Traveller (Ranks of 2 or greater are considered officers).

New Advantages

Former Rank – 5 points/level
This is your military rank, except you are no longer in active service. Your former rank is a mark of achievement and competence and provides a reaction bonus. It also provides a suitable requirement for skills that are only available to officers.
Level     Former Rank
1         Rank 2 or 3
2         Rank 4 or 5
3         Rank 6
4         Rank 7

Education – 5 points/level
In the Imperium, education levels very significantly. An educated person is accorded more respect and receives a reaction bonus. It is also a prerequisite to some skills and presumes a greater general knowledge. It may be used as a modifier on rolls to see what a character knows. (GM discretion).

Level     Description            Modern equivalent
0         Basic education        High School/Trade school
1         Higher education       College
2         Advanced education     Graduate/Professional School

Free Trader – 20 points
Merchants or ex-merchants may "own" a 200 ton type A Free Trader (or at least a piece of one). The PC is responsible for expenses and monthly payments (150,000 Cr for 40 years). Player is responsible for figuring out how his character was able to come up with the down payment and convince the bank he was a suitable risk (however, any reasonable story will be accepted). For an extra 5 points, you can add standard weaponry (Beam Lasers, Pulse Lasers, Missiles, Sand Casters) to the allocated hard points.

Scout – 30 points
A scout or ex-scout may have a 100 Ton Type S Scout/Courier that the scout service has loaned to you (dependable PC's only, GM judgment, former rank and status help). It may not be sold or mortgaged. The ship may be used for limited commerce but the scout service gets a 50% cut on all (net) profits and any information from any explorations. The ship (and you along with it) can be recalled to active service at any time. Scout bases will provide free fuel and maintenance (class B or better), the character carries other expenses. Character has a – 5 point Duty to the scout service (counts against limit). For an extra 7.5 points, you can add standard weaponry (Beam Lasers, Pulse Lasers, Missiles, Sand Casters) to the allocated hard points.

(Note: A GM may wish to allow players to pool points toward ownership of a ship)

Travellers' Aid Society Membership – 10 points.
This society provides hostels and facilities at Class A and B starports and provides 1 high passage every 2 months.


Since, in Traveller, a character's age helps to determine how capable the character is, the skill point limit of twice age should be strictly enforced. In Traveller it is possible to need to learn to use a Vacc Suit on worlds with vacuum or corrosive atmospheres. For that reason the Free Fall prequisite is dropped. However, in zero G situations, any use of a vacc suit will be a the minimum of the two skills if Free Fall is <12 (in addition to any other limitations ).

New GURPS Skills

Broker – M/A (prerequisite, Merchant); Training specifically in assisting the purchase/sale of good for interstellar commerce.

Steward – M/E; Training in the care, feeding, and management of passengers.

Forward Observer – M/A; Training in calling on, and adjusting fire from, batteries and orbiting ships. Includes knowledge in the capabilities of such weapons in various roles.

Interstellar Astrogation – M/H (Requires Astrogation); Making sure your ship jumps to the right place. A normal failure means you ended up further out from the system than intended. On a critical failure, another skill roll is made. Making the roll gives the same result as given above for a normal faliure. A failure means you ended up 4d days out from the nearest Gas Giant or Starport. A critical failure means you jumped to the wrong spot.

Engineer, Jump Drive – M/VH; Building and servicing Jump Drives.

Piloting, Interstellar – P/A (Requires Piloting, Spaceship. No default); Getting a starship to jump correctly. A normal failure means the jump failed and you have to wait 1 hour, for each point you missed by, before you can jump again. On a critical failure, another skill roll is made. Making the roll gives the same result as given above for a normal failure. Missing means were able to abort in time and your ship was thrown 4d days travel in a random direct (you use half the fuel you would otherwise have used). A critical failure means you have misjumped. (Note: A ship in poor repair, too close to a planet, etc., may also require a misjump roll as specified in Traveller).

Zero-G Combat – M/A (Requires Free Fall); All combat skills in free fall are at the minimum of either combat skill level or Zero-G Combat.

Tech Levels

The assignment of TL's past GTL/TTL 7 is necessarily arbitrary. For Game purposes (skills, ads, disads, etc) the following Traveller Tech levels are defined as the following GURPS Tech levels. (The Traveller description of what is available at each level applies)
TTL   0   1     2   3   4   5   6   7   8   9  10  11  12   13   14   15
GTL   0   1-3   4   5   5   6   7   7   7   8   8   9   9   10   10   11


In the Imperium, disapproval of psionics exists at both the popular and official levels. For starting character to posses psionic training (skills) requires a 10 point unusual background.

A player may buy powers without the background and attempt to be trained in skills after character creation. The character gets one IQ roll a year to realize that he/she is potentially psionic and then must find the Psionic Institute (as per Traveller rules) to try and get training (paying appropriate fees).

Characters who start without psionics will, if they successfully contact the Psionics Institute, have a chance of buying psionics (character will have to pay all necessary points at that time). The roll is up to the GM. One possibility is an IQ-3 roll on a power to see if any talent exists (if successful, roll again, at a cumulative -1 penalty, on a new power). For each success, roll 2d6 for the number of levels (with a successive -1 each time after the first one).

The following powers and skills are designed to match those given in the Traveller rule book. GMs shouldn't feel inhibited from adding additional abilities if it fits their campaigns.

Power          Skill
Telepathy      Mind Shield
               Life Detection
               Emotion Sense
               Mental Blow
               Mental Stab

ESP            Clairvoyance

Psychokinesis  Levitation

Teleportation* Autoteleport
               Combat Teleport

Healing**      Healing
               Suspended Animation
* The limitation that objects retain orientation and speed is mandatory. ** The limitation, self only, is mandatory

Life Detection – works with the same modifiers as Emotion Sense but detect living organisms. User can "ignore" bacteria or unimportant animals in the area. +1 for intelligent minds, -1 for unintelligent minds, Shielded minds are not detectable.

Suspended Animation – works like metabolism control. Character can last for 7 days without the need for food or water and with minimal air (5% normal). May be stopped at any time provided with external stimulus (alarm, slap, etc.) but there is no "internal alarm". Cost 1 Fatigue (when you wake up). Cannot be used to fool lie detectors.


In general, Traveller prices and capabilities are used for equipment. Lists may be expanded by adding from GURPS Basic and GURPS Space. GURPS and Traveller prices don't correlate well, but the average seems to be 2-3 Cr = $1.


Available Melee Weapons; Dagger, Blade (Heavy Knife), Foil (Rapier), "Cutlass" (Broadsword but single bladed with basket hilt), Sword (Shortsword), Broadsword (Bastard Sword), Polearms, Spear, Club. Base price listed in Traveller represents a "fine" quality weapon.

In addition to description given in Traveller, ranged weapons have the following GURPS stats . . . .

Submachinegun – Can be fired one handed (add 3 to SS, subtract 3 from ACC, double Rcl).

ACR (Advanced Combat Rifle) – Takes either high density discarding sabot ammo (HDDS) or high explosive ammo (HE). HDDS rounds divide DR and damage after DR by 3. HE rounds double DR, it does 5d damage + 1d explosive damage (x5 if buried in meat,no blow through).

Snub Pistol – Characters with Zero-G combat at 12+ can use one in free fall with just a -1 recoil penalty. Takes tranquillizer, armor piercing explosive (APE), and high explosive (HE) rounds. Shots are very low velocity and may be blocked as per arrows. APE rounds explode with a small shaped charge as the hit the target doing an extra 1d of damage (DR is halved as is damage). HE rounds are as per ACR HE rounds (but you must do at least 1 point of damage to "bury" the round).

Accelerator Rifle – Characters with with zero-G combat at a 12+ can use one in free fall with just a -2 recoil penalty.

Gauss Rifle – Round is a dense armor piercing core surrounded by a softer metal covering ending in a hollow point. Divide armor by 3 but damage that penetrates by 2. Grenade Launchers – Grenades from both kinds of grenade launchers do 5dx2 damage. A RAM Grenade Launcher can be fired on a flat trajectory like a gun. Character uses guns skills but can also use telescopic sights, etc.

Other Equipment

In addition to other description, the following equipment has the following stat in GURPS . . .

Telescopic Sights – 32x power, variable.

Shoulder Stocks – For pistols, 2.5 Lb, add +4 to Acc and +2 to SS and you use Guns, Rifle instead of Guns, Pistol.

Vacc Suit – Provides PD 2, DR 3.

Computers – For personal computers use GURPS rules, GTL 8, $1 = 2 Cr. Ship computers use Traveller rules.

Slow Drug – Allows user to take 2 actions/round. Takes 4 seconds to take effect. Last for 30 second when the user makes a HT-4 and take 1 point of damage for each point the roll was missed by. Hypo form only.

Medical Slow Drug – Renders the subject unconscious for one day, during which 30 days of healing occurs. Requires medical supervision to be used safely. Attending physician makes a roll and then the character makes a roll against HT+2+amount physician roll was made to avoid side effects (GM's judgement).

Fast Drug – Character uses 1 day of food/oxygen/water every 60 days. One dose lasts 60 days unless countered by an antidote. Requires a HT+2 roll to avoid side effects (GM's judgement).

Combat Drug – Increases ST temporarily (30 seconds). Takes 2 rounds to take effect. When it wears off the subject makes a HT-total bonus roll and takes 1 point of damage for each point the roll was missed by. Doses can be bought that provide a +1 to +3.

Truth Drug – Subject is compelled to answers questions truthfully. Lasts 2 minutes. Subject then goes unconscious for 1 hours and makes a HT-7 roll, taking 1 point of damage for each point to roll was missed by.

The following drugs out of Space are also suitable ($1 = 4 Cr) . . . Antirad, Analgine, Hypercoagulin, Superstim.


Descriptions are as given in appropriate Traveller supplements.

Aslan, 31 points
Aslan have ST +2, DX -1, HT +1, Claws (+2 damage, 15 points), Acute Hearing +2 (4 points), Night Vision (halves darkness penalties, 7 points), Enhanced move (only for 5 seconds, then fatigue penalties start to apply, 7 points), Code of Honor, Aslan (-10 points). Aslan male PC's may want to take a female ally to help them function in imperial society. All Aslan PC's will need to consider Aslan society and have a reason why they are wandering about the Imperium and are not back with their clan. Character choice of skills should be consistent with gender roles in the Traveller Aslan supplement. An Aslan who openly disregards Alsan code of behavior will have a Social Stigma (-3 reaction, Aslan culture only, -5 points, counts against limit) and a 5 point unusual background.

Droyne ,Variable
All Droyne have; Night Vision (halves darkness penalties, 7 points), Claws (+2 damage, 15 points), Invisibility (Can become invisible at will, doesn't affect purely mechanic devices such as robots, recorders, etc., 60 points), Winged Flight (Thick atmosphere/light gravity only, 15 points), Peripheral Vision (15 points), Fragile -20 points. Each caste has is own functions (see skill list in Traveller supplement) and a character should take suitable skills. Because of caste rigidity, Droyne don't use careers. Additionally, each caste has . . .

* While these characters will take initiative and make decisions, they will defer to, and obey, memebers of the Leader caste. -5 points.

** A mild form of slave mentality. Character will care for itself and be able to pursue task in natural directions. He/she will not take on new task or make fundamental decisions about where the project should go. When a task is finished, or when a reaches a point where a fundamental decision needs to be made about direction, the character will need the direction of a leader. -20 points.

Droyne have the following additional available Telepathic skills; Boost, Mindwipe, Link. Link is part of the permanent bond between members of a dreskay. For 15 seconds the character will see and hear everything the linked character experiences and knows his direction and distance. Costs 1 fatigue. Boost allows another psi to draw from the character's fatigue. Costs subject 2 fatigue per point of fatigue drawn. Each activation allows the other psi to draw fatigue for 10 minutes. Failure costs 1 fatigue.

Hiver, 55 points
Hivers have ST -2, HT +2, -2 Hit points, Infravision (15 points), Clinging (30 points), 5 Legs/Arms (70 points*), Pacifism (Will not engage in personal combat, – 10 points), Social Stigma ("Bug Eyed Monster" -2, -10 points), Odious Racial Habit (Occasionally drop larva, - 1, -5 points), "Mute", -25 points

*All five legs/arms have manipulators. However, you need 2 to stand on (and that's kinda like standing on one leg).

K'kree, 15 points
K'kree have HT+3, ST -2 (upper bodies only, -5 points*), Increased ST (lower bodies only, 30 points*), Enhanced Movement (10 points), 4 legs (5 points), Inconvenient Size (-10 points), Claustrophobia (-15 points), and Fear of being alone (-10 points). A K'kree will generally need an ally group.

*The net effect is to give a K'kree a split ST. You buy ST normally. For task using the lower body only the ST is (ST-2)x2.

Vargr, 14 points
Vargr have ST -1, DX +1, Acute Smell +4 (8 points), Acute Vision +1 (2 points), Enhanced move (only for 5 seconds, then fatigue penalties start to apply, 7 points), Claws (+1 damage, 7 points), Night Blindness (double darkness penalties. -5 points), Reputation, Disloyal -1 (-5 points). Additionally, their Hearing is in a higher range than human. They can't kick but can bite for 1d-1 damage in close combat. Reaction bonuses/penalties for Charisma are doubled with Vargr. Success or Failure at important tasks may raise or lower a Vargr's Charisma.

Since they are human, no racial package applies. All Zhodani PC's should take Honesty and Truthfulness. The Zhodani Consulate is current opposed to the Imperium so Social Stigma or Enemy might also apply.


There are no hard and fast rules for converting animals. If you have a good idea what it's like, then the best thing is just to modify the most similar animal you can find in GURPS to suit the description. For example a 100 Kg pouncer carnivore might be similar to a 200 Lb Cat (for example, a Jaguar).

One can come up with rough guidelines as to what a Traveller animal should look like in GURPS. PD/DR would be similar to that of the armor listed under the "armor" column (Jack = PD1/DR1, Mesh = PD2/ DR3, Cloth = PD3/DR6). Damage is similar to 1d-4+(wounds/2) (where every +4 is replaced by a second dice, ie 1d+5 = 2d-1). For hit points, take the number of hits it takes to render an animal unconscious and dead, then add them together (which we will call "total hits", TH). TH/2 to TH seems to be the range, with numbers generally closer to TH (particularly for larger animals).

Note . . .

Some people have asked me about using GURPS Vehicle rules for Traveller type ships. To do this, you need one main principle, that volumes and masses for components in Traveller are compatible with GURPS Vehicles and GURPS Space. (Stats from MegaTraveller work better because it provides both volumes and masses).

First you take the volume of the ship you are designing and look up the volume, or volume and mass, of a jump drive big enough to give the proper jump rating. Then you look up the amount of fuel the jump drive needs. (This is so the logistics of travel, trade, and war work the way they do in the Traveller universe). At this point you can . . .

  1. Just proceed under GURPS rules, using the Traveller stats for the size and volume of the Jump unit and the fuel it needs.

  2. Proceed under GURPS rules, but assume that the power plant requires as much fuel as given in Traveller for a maneuver drive on a ship that size. (GURPS Fusion plants are efficient enough that they almost never need refueling and the GM may not want to relieve the players of the worry of running out of fuel).

  3. Look up the Traveller stats for the power plant, manuver drive, and manuver fuel requirements and use those (along with jump drive stats) to design a ship. (You pretty much just ignore power requirements because it is assumed that, once you have powered the manuever drive, any other power requirements are not significant.)
You will need at least on of the following conversions . . . .
One Ton (of disp. of hydrogen) = 18 cubic yards
One Ton (of disp. of hydrogen) = 13.5 kiloliters
One Ton (of disp. of hydrogen) = 486 cubic feet
