- in-game description
FOX (Frontial Operation X) is one of the female characters featured in CrossFire
FOX is considered by lots of players to be the sexiest character, and this reputation still stands by today. The GR character wears a dark blue skirt with neck buttons undone, partially revealing her bra, while BL wears a similar yellow version but has no sleeves, to showcase a tattoo on her left arm plus she has a cap on. Both characters wear long socks and high heels as well.
- Available in all CrossFire versions
- In Russia, FOX has their own Russian voice, similar to S.T.A.R in CF Korea.
- Even though the descriptions in CF North America state that FOX "stripped armor for speed", they don't actually run any faster than other characters.
- Like other popular characters in CF China, players cannot buy FOX permanently, they can only be rented for a period of time.
- However, in a recent update in CF China, FOX can be obtained permanently via Mileage Shop.
- FOX's GR HUD incorrectly shows hand models of the S.T.A.R, with black shirt and yellow stripe, although the gloves are correct. This happens because FOX's HUD is just a recolored version of S.T.A.R.'s HUD. It has been fixed in most CF versions, but still exists in CF Vietnam & CF Europe.
- CF PH and CF NA released the character during the popularity of the song "What Does the Fox Say?".
- In CF Japan, she can be won permanent or 30 days.
- FOX is featured as the promotional tritagonist in CF China's Shipyard CG movie, helping the two protagonists escape death after they got transported to the Shipyard. She is shown wielding Dual Desert Eagle-Black, which is unavailable in CrossFire but this skin exists in early renders (Hinting it's a beta weapon before Zombie Mode was released).
- FOX also has an "undercover" variant, named FOX Undercover, featuring more casual outfits for both BL and GR.
- FOX is one of the 3 prizes (along with Datura and Orchid) as CF VN fanpage reached 1 million likes. Everyone qualified for the event (Play at least 1 game and get at least 1 EXP on July 1st 2016) will receive FOX by default if they don't have any of the three characters - the reason is likely because the appearance of FOX Undercover, so VTC chose to giveaway FOX by default.
- Following this event, FOX has became the most popular female character in CF Vietnam, as can be seen in almost all rooms in every server. Behind it is the SPOP-X, which can be obtained from Mileage Shop (perm. or temp.).
- Later, similar to CF China, she is also being sold in Mileage Shop with the price of 13k MP, same price with permanent SPOP-X. This even makes her more popular with CF Vietnam players.
- BL FOX appears to have blue eyes & blonde hair, which are among the most recognizable features of girls & women coming from Russia.
- CF Indonesia set FOX as login page wallpaper upon her release. Because of this, they got many critics and protests because these FOX's wallpapers are considered to be too revealing for underage players. GM then removed these wallpapers after a week.
