Shadowrun to Cyberpunk

Characteristics

Shadowrun to 2020: Shadowrun Attribute/Skill x1.666 = 2020 Attribute, /2 again for Skill value, with rounding.

These are the minimum and maximum values that can be allocated out of the starting points total.
In SR2e, non-human Metahumans start with 2 Karma, hence the higher minimum LUCK. For converting SR3e, non-human LUCK is instead capped at 1/7, as humans start with more Karma and others at 1.

Guns and Gear

Shadowrun 1e converts to Cyberpunk 2020 as: halve the Power level if an L-class weapon, keep the Power level as is if M, S or D. Halve the Staging number and keep as a damage bonus if an L or M-class weapon, keep as is for an S-class or D-class, then apply as a bonus to the damage. D-class weapons do damage in d10s and all others in d6s. If halving produces a 0.5, round down and add +3 to the staging before conversion.

For Shadowrun 2e/3e, the number were changed again producing an irregular power increase, one should only use one set of values when converting. Halve the Power for all classes and deduct 1 for L-class weapons. Assign that Power rating as the damage in d6s (except D-class weapons which do d10) then for S -class weapons, add halve the new Power rating as bonus damage. Any results of 0.5 during conversion convert as +1.

12 Gage Shotguns remain 4d6/2d6/1d6 for legacy reasons

Heavy Weapons

Flamethrowers remain 2d6 for legacy reasons

Concealability for Shadowrun to Cyberpunk 2020 is done by assign values to the Shadowrun weapon Conceal score: more than 6 = P, 5 = J, 4 = L and 3 or less = N.

WA is annoyingly determined by taking the Shadowrun 5e Accuracy value and deducting 5. Fortunately, there is a sourcebook for early Shadowrun decades for 5e.

Nuyen converts to Eurodollars at x1.3 (price increases by a third in EB), then rounded up to the nearest 50. For availability; Illegal weapons become Poor or Rare and Restricted weapons become Common or Excellent.

Converting to Cyberpunk RoF, converts as: SS = 1, SA = 2, BF = 3, FA = 10 because Shadowrun considers all guns with automatic fire to shoot 10 bullets every combat action and turns are the same length in both systems.

The armor conversion equation for Shadowrun 1e through 3e to Cyberpunk 2020 is: Ballistic + Impact ratings x 1.75 = SP, unless it's the armor in Shadowrun 2e Fields of Fire, then that equation is Ballistic + Impact x 1.3125 = SP.
