- Infernal Dragon (most versions).
- Serpent Dragon (South America).
- Panlong Dragon (China).
- Dragon (Russia).
The RPK-ID has various effects to its owner and every other players in the room. The effects are:
- 200% Exp bonus for the owner
- 30% Exp bonus for everybody in the same room
- 20% GPs bonus for everybody in the same room
- 50% Points bonus in Zombie Mode for the owner
- 10% points bonus in Zombie Mode for everybody
- Addtionnal twenty bullets for every machine gun owned
Thus meaning the owner will have 170 ammo by default on his RPK-ID or 190 if he owns two and equips both. If he trades the gun, the ammo will be 150 for whoever picks it up.
- This gun was supposed to come alongside AWM-ID in CF Vietnam as of July 2013 patch, but it was left out for unknown reason. Only one month later it was added to VVIP Shop.
- RPK Infernal Dragon is the only VVIP gun not to feature any sale-off upon its release in CF Vietnam. The M4A1-Transformer has the same problem, albeit it could be bought in a package with Wave Mode stuff (Gems, Gem Removal Coupon and Stabilizer device) at no cost for bonus items.
- Prior to this gun's release, both AK47 Beast and AWM Infernal Dragon received discount on the webmall (500 vcoin for AK47 Beast and 300 vcoin for AWM ID, applied to users who already own AK47 Beast).
- Unlike the Points Bonus glitch, the RPK-ID owner will receive the 60% Bonus on-the-fly during ZM match. This applies to both score against zombies/mechs and the Clear Bonus points at the end of each rounds (kill streaks in EMD Lab excluded). This ensures that user with RPK-ID will always get the most points for themselves before anyone else, and in case they get kicked/disconnected, they will still be able to keep some prizes.
- The points bonus in ZM is displayed after each round ends, except the last round and Mission Bonus, though players will still receive full bonus points.
- Due to its various bonuses and fair price, the RPK-ID is considered the best VIP gun released up to date. It is highly recommended for players who like Mutation and Zombie Mode, although the Thompson-ID could also be considered.
