Additionally, weapons can be sold to Drebin in order to acquire Drebin Points (DP). These weapons are sold and DP is awarded according to the formula detailed below. Be aware that this formula applies even before Drebin is met for the first time in game, and awards points despite no visuals being displayed, counter to what the official guide states.

DP = Gun Value * Method of Acquirement * Difficulty & Act Scaling

And the formula for machines is similar.

DP = Machine Value * Difficulty & Act Scaling

Gun/Machine Value

Gun Value is a fixed number, intrinsic to every weapon when it is picked up from the ground. The above and below tables detail these values. Of the below table, only the AK-102 & Chaff G. can be acquired multiple times in a single play-through, and only the AK-102 selling value applies to a New Game, as the other weapons can only be acquired once per play-through or, in the case of chaffs, a maximum of 8 can be picked up per play-through, barring the infinite farm loop, which is not enough to reach the maximum allowed amount.

Weapon Subtype Act # 1st Pickup Location Notes Selling Value (DP)
Mk. 23 Handgun 4 Helipad Under Truck 5000
AK-102 Rifle 0 Ground Zero Required
One Less DP (BBH)
900
XM8 Rifle 2 Power Station 2 Left Path 3000
VSS Rifle 2 Confinement Facility Left Path 5400
Chaff G. Explosive 2 Power Plant 4 Total Locations 1500
Mantis Doll ETC 5 Command Center Required 10000
Sorrow Doll ETC 5 Command Center Optional 10000
Machine Name Machine Value (DP)
Irving (Gekko) 500
Raven Drone 100
Scarab (Dwarf Gekko) 50

Method of Acquirement

Method of Acquirement has four possible values: 0.1, 0.2, 0.3, or 1.0.

  • 0.1 is obtained by defeating the wielder via lethal means, machine or human, and picking up their weapon
  • 0.2 is obtained by stunning, knocking out, or putting to sleep the wielder and picking up their weapon
  • 0.3 is obtained by defeating an enemy using an environmental effect, such as a barrel or NPC
  • 1.0 is obtained when a weapon is picked up, from the ground while full, such as grenades, or after already acquired, such as the XM8 or Javelin, and sold directly to Drebin. This can occur for weapons received from hold-ups, CQC disarms, Emotion Rounds causing an enemy to drop their held weapon, and pre-placed spawns.
  • Certain weapons, such as the AK-102 on BBH, MK. 17 on TBE, and WP G. on TBE actually reward 1 fewer DP then intended when the Method of Acquirement is 1.0.


Difficulty & Act Scaling

Difficulty & Act Scaling is a scaler multiple. These values are listed in the below table:

Acts 0, 1 & 2 Act 3 Act 4 Act 5
LE, NN & SN 1.00 1.20 1.50 2.00
BBH 0.80 0.95 1.20 1.50
TBE 0.50 0.60 0.75 1.00

So for example, if you picked up MK. 17 in Act 3 from an enemy you tranquilized on Big Boss Hard, you would get DP = 1050 * 0.2 * 0.95 = 199
If you defeated a Scarab (D.E) in Act 4 on TBE and picked up the D.E. you would get DP = 50 * 0.75 + 10000 * 0.1 * 0.75 = 787

This was confirmed by the official guide Condition & Battlefield Multipliers

Drebin Points are also rewarded based on Snake's performance through the act. Act Result Drebin Points
