Skill Extraction Card

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

Beside the common skills which can be found in characters obtainable from AI Ticket, this system now features more skills that are specialized in some 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 save in the extraction tab storage.
