NPC conversion from T2K 1.0
The most important thing first:
If you want to play the old modules with the V4 rule set, you only need these two elements.
1. NPCs
T2K 1.0 uses four classes of NPC, Novice, Experienced, Veteran and Elite. Use them as follows:
Novice: Attribute C, Skill Level D, CUF D
Experienced: Attribute C, Skill Level C, CUF C
Veteran: Attribute B, Skill level C, CUF B
Elite: Attribute A, Skill level B, CUF A
Add specialities fitting to the job description.
2. Tasks
Task Conversion.
V1 has the following skill Levels: Easy, Average and Difficult.
Easy (ESY) = Add two Levels, e.g. a D8 becomes a D12.
Average (AVG) = Unchanged
Difficult (DIF) = Detract two Levels, e.g. a D10 becomes a D6, a D8 or D6 would convert to attribute die only.
Converting Player characters from V1 to V4
Attribute Conversion Table:
1-8 D8-10 C11-13 B14+ A
STRENGTH(STR)Add Fitness, Constitution and Stature together and divide the result by 3, round fractions up. Compare the result to the Attribute Conversion Table on page XX. The result is the STRENGTH(STR) attribute.
AGILITY(AGL)Agility corresponds directly to AGILITY(AGL)
INTELLIGENCE (INT)Add Intelligence and Education together and divide the result by 2, round up any fractions. Look up the result in the Attribute Conversion Table on page XX. The result is your INTELLIGENCE(INT) attribute.
EMPATHY (EMP)Since T2K 1.0 has no empathy attribute, this will be based on the existing skills. For each of the following skills the character possesses, add 3 points to Empathy.
Disguise, Equestrian, Instruction, Interrogation, Language, Medical
Compare the final result with Attribute Conversion Table, the result is the EMPATHY(EMP) attribute.
SKILLS
Use the highest skill the character has in the area and compare it to the following table.
Now add the speciality that compares to the skill (see table on page XX).
By adding the +1 for the speciality, the actual roll will be done with a die one category higher, e.g. with a skill level of D this is a D8, with a C this is a D10, and with a B it will be a D12.
Example: The character has the TECH(INT) skills of Gunsmith 65, Chemist 30 and Computer 10. Gunsmith is the highest of those Tech skills, so the character will have a skill level of C in Tech and, by adding the specialisation, this would allow him to roll a D10 base die for his skill rolls in TECH(INT).

Driving (AGL)Ranged Combat (AGL)Mobility (AGL)
Recon (INT)Survival (INT)Tech (INT)
Command (EMP)Medical Aid (EMP)Persuasion (EMP)
Skills in V4 are a combination of one of the 12 core skills plus a speciality that usually rises the skill level by one factor but can have other properties, too.
To find the skill and speciality, look up the V2 skill in the skill table and see the corresponding V4 skill and speciality below.
Use the highest skill the character has among the CORE SKILLS and compare it to the following table.
Now add the speciality, that compares to the skill.
By adding the +1 for the speciality, the actual roll will be done with a die one category higher, e.g. with a skill level of D this is a D8, with a C this is a D10, with a B it will be a D12.
Example: The character has the TECH(INT) skills of Gunsmith 6, Chemist 3 and Computer 1. Gunsmith is the highest of those Tech skills, so the character will have a skill level of C in TECH(INT) which corresponds to a D8 and, by adding the specialisation of Gunsmith, this would allow him to roll a D10 base die for his skill rolls in TECH(INT).
The following table contains all the T2K 2.2 skills, followed by a description and the corresponding Core skill and the fitting speciality.
Twilight 2000 V2.2 in some cases uses different core attributes, e.g. Aircraft Mechanic is a STR based skill while it corresponds to TECH(INT), MECHANIC in V4, e.g. is INT based. In such a case choose which core attribute you want to use and record it accordingly. In this case it would be TECH(STR), MECHANIC if you want to stay with the origninal V2.2 values.

T2K 2.2 Vehicle template conversion
Price: $650,000 (R/R) - Add 50% to the price, to get the price in V4.
Fire Control: +2For any version of fire control add an FCS to the MAIN WEAPON COLUMN, in game this will negate the negative DM’s for shooting at ranges beyond short range.
Armament: 120mm gun: see below
MAG MG coaxial, M2HB MG (C), MAG MG (L): see the equivalents on pages xx-xx in the Players Manual.
Stabilization: GoodStabilization reduces the penalty while shooting on the move. The basic penalty when shooting on the move is -2 without stabilization. Fair stabilization reduces the penalty to -1. Good stabilization reduces the penalty to 0.
Ammo: 40x120mm, 1000x.50 BMG, 11,400x7.62mm – no changes in V4
Fuel Type: D, G, AvG, A – no changes in V4
Load: 700 kg – no changes in V4
Veh Wt: 54 tonnes – no changes in V4
Crew: 4 – no changes in V4
Mnt: 14. There is no equivalent to the Maintenance number in V4, all vehicles start with Reliability A.Here is an optional method to use maintenance in V4. One tech roll can be made per person per shift. Multiple rolls by different persons are possible. If the number of necessary successes has not been reached, the vehicle reliability rating is decreased one step at the end of one week.
Concept: In combat and off-road conditions vehicles will suffer. Treads have to be tightened, spark plugs and filters need cleaning. Most of this work can be done by untrained people if someone shows them what and how to do it. So its basically a time thing. Time that might otherwise be used for foraging, sleeping, after all time is precious. Use the T2K 2.2 maintenance number, e.g. the number of hours per week that have to be spent on maintenance to keep the vehicle in good condition. Divide the number by 7, ignore fractions and add the vehicle weight divided by 20. If the result is smaller than 1 raise it to 1.
MNT = INT(maintenance / 7 + vehicle weight / 20)
Apply the following DMs to the tech roll:
- Original vehicle tools are available +2- No tools are available -4
Night Vision: Passive IR/thermal (shared by commander and gunner) - no changes in V4
Radiological: Shielded – In a radiological shielded vehicle, you do not suffer from radiation. But there is the danger of a RAD ATTACK when you leave the vehicle without wearing protective gear. The vehicle has to be contaminated before it is safe again.
Tr Mov 130/110
To translate this to the V4 values, divide both values by 14 and round fractions up.
Com Mov: 35/30
To translate this to the V4 values, divide the ComMov values by 7 and round the results down. Since there are mismatches between Travel and Combat with some vehicles in the V2.2 rules, you can alternatively divide TrMov by 28 to get the equivalent results.
AIRCRAFT
To convert aircraft speeds from V2.2 to V4 the formula is a bit different. In V4 a combat round lasts 5-10 seconds, movement is measured in 10 meter hexes, so each movement factor equals approximately 7.5 * 10 = 75m per round.
In V2.2s Nautical and Aviation handbook (GDW 2009) the combat move of an aircraft equals its maximum speed or "never exceed" speed in kilometres per hour divided by 10. This results in the number of eight-meter squares moved in a combat phase, in sync with the basic game combat movement system. Since 2.2 has 5 second rounds, this equals 5 x 8 = 40m per round.
An UH-1 has a maximum speed of 220 km/h. Divided by 10 = 22. This equals 22 x 40m = 880m per round. Divided by the average of 75m from V4 you get 11.73, rounded to 12.
So the formula is V2.2 combat speed divided by 1.875, or maximum speed divided by 18.75 or, to simplify it even more, just halve the combat speed.
TURNING: If an aircraft has a stalling speed (the value in parentheses after the combat speed) it is limited in its turning radius. It can only bank once in a turn (one hex-side) after having moved for at least half of its stalling speed in distance. After this it has to move at least the other 50% its stall movement to stay airborne.
Example: A C-130 Hercules with a Combat Move of 52(18) will translate into 28(10) for V4. The smallest achievable turning radius would be one hex side after 5 hexes (50% of stall speed) movement.
Combat: An aircraft with fixed weapon mounts can only fire at targets that lie directly ahead of its flight path, e.g. it can either fire before or after its turn but only on targets straight ahead.
Fuel Cap: 1900,Fuel Cons: 1100
Fuel capacity remains unchanged, to get the fuel consumption per 10km hex, divide fuel consumption by 27.5 and round the results down, to get that value. If you want to have a more realistic formula that takes speed into account, use Fuel consumption divided by TrMov multiplied by 5.
Armor Conversion
The effective protection factor of modern armor is measured in Line of sight (LOS) thickness. The more the Armor is sloped, the better its protection. The formula is:
Amour LOS = Armor thickness / cos(angle)
In addition modern armor usually consist of sandwiched or spaced layers of different materials from steel over ceramic to depleted uranium, the colloquial term is usually Chobham, named for the British tank research centre on Chobham Common in Surrey, UK.
A common measuring factor is RHA (Rolled homogeneous armor) to express the effective armor value of modern battle tanks. In addition the effectiveness is also expressed differently for kinetic Penetrators (APFSDS) and shaped charges (HEAT). Usually the effectiveness of sandwiched armor via HEAT is 30% higher than vs. kinetic projectiles. So, as an example, the armor of the Leopard 2A4 has an equivalent protection of 700 mm RHA against kinetic projectiles and 1000 mm vs. HEAT.
For game purposes: Any HEAT round that attacks such armor (Chobham (-Cp)) has an additional armor modifier of +2. Spaced (-Sp) has a similar but weaker effect compared to -Cp, the additional armor modifier is only +1. Reactive Armor has the same effect as Chobham armour, but after a hit, roll 2 ammo dice – if one of some shows a 1 the reactive armor on that face of the tank is gone.
T2K 2.2 uses a system, where armor and penetration values are twice the relative armor strength in cm, e.g. an armor value of 100 is the equivalent 50 cm of hard steel at 90° or 33 cm with a moderate slope. Since V4 uses only the front side and rear armor values, you can either use the hull (HF,HS,HR) or turret (TF,TS,TR) values or add the faces (HF+TF) and divide the result by 2.
Modern Anti tank weapons come in two flavours: Shaped charges (HEAT) and Penetrators (AP).
While the concept of a shaped charge dates back to the 18th century, it took until the 1930s that a military application was developed. The explosive charge collapses a funnel shaped metal liner inside the warhead into a high-velocity super plastic jet that is capable of penetrating armored steel to a depth of seven or more times the diameter of the projectile containing the charge. Against steel armor this proved devastating but against modern composite armor, not so much. The most important factor with HEAT is, that the penetrative power is not based on the speed of the projectile, so that they can be fired from low powered, nearly recoilless weapons. This gave rise to the handheld anti armor weapons like the Bazooka and the Panzerfaust and later the anti tank guided missiles.
The purely kinetic projectile is basically the centuries old, primary form of any cannonball or bullet. This changed drastically in WW2, when the first kinetic penetrators arrived on the battlefield. In most cases the rounds were capped (APC) with the hardest material available, usually some kind of tungsten alloy. The next step was the discarding sabot (APDS) where a sub calibre penetrator was used. But these projectiles needed a rifled barrel to be fired, needing the spin generated inside the barrel to be accurate. The fin stabilized, discarding sabot (APFSDS) was the next development. As in APDS the casing of the round contains a dart of extremely hard material that is much smaller than the calibre of the gun firing it. The fins give it a spin, so that no rifled barrel is needed for firing the darts. The small darts (2-3 cm in diameter), propelled by the power of a 12 cm round, can reach much higher velocities (over 1700 m/s) and combined with ultra hard materials (Tungsten or depleted Uranium) they are truly devastating.
120mm smoothbore gun
The M1A1 has a 120mm smoothbore that can shoot APFSDSDU (Armor piercing fin stabilized discarding sabot depleted uranium) ammunition. Its short range is 500 m and it has a penetration of 150 = 75 cm hard steel, at that range.
Rng 500 : This is the short range of the gun. Divide the range by 10 to get the distance in map hexes for V4, in this case 50.
150/140/130/110 T2K 2.2 uses a system, where armor and penetration values are twice the relative armor strength in cm, e.g. an armor value of 100 is the equivalent of 50 cm hard steel at 90° or 33 cm with 50 degrees of slope.
For rounds, especially anti tank rounds, only the penetration factor is important for vehicle combat. Armor piercing rounds (AP) have different penetration values at different ranges, so the penetration at short range is 150, at medium range 140, long 130, and at extreme range 110.
For V4, in most cases, only the penetration at short range is needed, since the 4 values usually stay in the same band. In any case, compare the values to the numbers on conversion table on page xx.
In the case of the 120mm APFSDSDU round it would be 12 on Short, Medium, and Long, and 11 on
Extreme range. Since you will nearly never have the opportunity to fire at extreme range in the post-apocalyptic world of Twilight 2000, the 12 is sufficient for game purposes.
HEAT rounds have a constant penetration at all ranges, so here 110C (C for constant) translates to 11.
Each cannon or mortar also has a Blast damage value when using high explosive (HE) ordnance. Armor piercing penetrators usually carry no explosives, so only ammo types that have a HE in the name generate Blast.
If the calibre is smaller then 75mm the Blast factor is D.
If the calibre is between 75 mm and 90 mm the Blast factor is C.
If the calibre is between 90 mm and 140 mm the Blast factor is B.
If the calibre is larger than 140 mm the Blast factor is A.
Rng - Range, divide the range by 10, round fractions up.
DAM - Damage, deduct 1 from DAM damage and add a Crit threshhold of that value +1, if the calibre is greater than 9 mm the Crit threshold equals the damage. In case that the weapon has a Damage of 1 (e.g. the new value would be 0) leave it at 1, but rise the Crit threshold instead. If the weapon uses HE ammunition lower the Crit threshold by 1. If the weapon uses HEAT ammuniton lower the Crit threshold and the Armor value by 1.
