The RPK is found in the missions Operation 40, S.O.G, The Defector, Victor Charlie, Payback, and Redemption. It is quite accurate, and deals significant damage (Enough to gib enemies). It can be found with an ACOG sight, Drum Mags, Dual Mags, and an Infrared Scope.
In multiplayer, the RPK is unlocked at level 6, and features good stats overall. The RPK has no damage drop-off, achieving kills in 3 hits at any range (or 2 with a headshot). The RPK's main drawback is its high recoil. To combat this recoil, those using the RPK will have to fire in burst or in semi-auto at most ranges to remain effective. The Dual Mags or Extended Mags attachments are good choices as the gun's 40 round magazine will empty quickly and the reload animation is quite slow. Using the Extended Mags gives the player an 80 round drum that reloads as fast as a normal box magazine. It should be noted that unlike other weapons, the Dual Mags attachment does not grant extra reserve ammo; because of this, Extended Mags is recommended over Dual Mags, as while Dual Mags gives a faster reload after 40 rounds, Extended Mags completely eliminates the need to reload after 40 shots altogether. The RPK, despite being a light machine gun, can hold its own in close quarters due to having good hipfire accuracy for its class.
The usual assortment of sights and scopes are available for the RPK. While the Red Dot Sight and Reflex Sight behave no differently than the iron sights, the ACOG Scope and Infrared Scope are not recommended, as the high recoil is magnified to extreme levels; the weapon is practically unusable with the Infrared Scope.
Overall, the gun is comparable to the HK21: while both guns sport the same damage and RPM, the HK21 has has a lower recoil and a smaller magazine.
When Extended Mags are used, the RPK can also be compared to the M60, especially when Extended Mags is equipped, as an effective suppressive fire weapon. While the M60 sports lower recoil (much lower with a Grip) and higher damage at close range, the RPK has a much better RPM and hipfire spread.

The RPK can only be found in the Mystery Box and supports a 100 round magazine. For the most part, it is quite similar to the HK21, however it trades a higher rate of fire for a slightly smaller magazine.
Speed Cola is necessary if the player chooses to keep this gun due to the slow reload time. Juggernog can be quite helpful when stuck in a corner with RPK's slow reload, paired with several zombies attacking makes Juggernog crucial for survival. Double Tap (if the player can control the gun) is helpful but will cause bad recoil from firing and mostly needs to be shot like the M16 for better accuracy if the player has Double Tap Root Beer.
The Pack-a-Punched version of this weapon is called the R115 Resonator. When upgraded, its round capacity is bolstered to 125 per magazine with 500 extra rounds and becomes more powerful
