Character Upgrade System is an upgrading system for characters in CrossFire.


Skill Swap Card

Skill Extraction Card

Like the name suggested, this system can upgrade some certain in-game characters (various between versions) that players can change or upgrade the skills based on players' needs. Characters can be upgraded up to two, three, or four skills with various options provided.

Besides the common skills which can be found in characters obtainable from AI Ticket, this system now features more skills that are specialized in certain modes. These skills are categorized as Normal Skills (colored blue) and Special Skills (colored gold). Both can be randomly swapped by using Skill Swap Card (obtainable from Item Shop, Mileage Shop or from Reward Crates in Zombie Mode) or can be extracted by using Skill Extraction Card thus said skills will be saved in the extraction tab storage for later use.

Players can use one Skill Swap Card to see another new skill, and decide whether to keep the old skill or use the new one (similar to Accessory System). Players can use 10 cards at once to see the list of 11 skills (10 from the cards, and 1 from additional bonus skills) provided and decide which skill to use.

  • The Emotion skill is the default for some characters like ULP-Renewal, and it can't be swapped to other skills, however.
  • In CF China, the Icon 29s.png and Icon 30s.png skill were initially for all upgradeable characters, even older ones like FOX-Seaside. Later then, Tencent stated that the two skills are limited to newer upgradeable characters (starting from STAR-Renewal, Girl Crush-Noble Gold and Sabel-X), and the incident which older characters can also see the two skills and successfully apply is a visual bug. They also stated any players that has applied the two skills in older characters will be compensated instead.
  • For unknown reasons in CF Vietnam, the Icon 18s.png and Icon 17s.png skill aren't included in the skill list.
