Call of Duty: Black Ops 4is still a fairly mysterious game, with a full reveal not coming until May 17. However, a recent tweet byCall of Duty: Black Ops 4studio Treyarch may reveal one of the first concrete details we have about the game’s multiplayer mode, and that is the return of the Pick 10 system.

Speculation that the Pick 10 system will return inCall of Duty: Black Ops 4began when Treyarch tweeted an image that appears to be what it will look like in the new game. The image was accompanied with text that indicated Treyarch will reveal more information about Pick 10 once May 17 rolls around and the studio is able to talk more openly aboutCall of Duty: Black Ops 4.

Check out the mysterious image right here:

For those unfamiliar withCall of Duty’s Pick 10 system, it essentially gives players as much freedom as possible when it comes to customizing their loadouts. Players have 10 points to spend, with each weapon, perk, etc. costing a point. Through the Pick 10 system, players could experiment with unique loadouts like having extra perks at the cost of more firepower and vice versa. The popular feature was first introduced inCall of Duty: Black Ops 2, but was dropped by the most recent entry in the series,Call of Duty: WW2.

If the Pick 10 system is returning inCall of Duty: Black Ops 4, it could be an indication that the game will have a multiplayer mode similar to the previous games in the series. However, rumors have been swirling aboutBlack Ops 4potentially making significant changes to the established formula to the point that itsmultiplayer is likeOverwatch. Of course,Black Ops 4could still potentially have a multiplayer mode likeOverwatchand mix it with the Pick 10 system, so that rumor could still very well be true.

Treyarch will likely clear the air aboutCall of Duty: Black Ops 4’s multiplayer on May 17. OnceBlack Ops 4receives its proper reveal, it will be interesting to see if the Pick 10 system is returning as this image suggests, and if there is any truth to the rumors about theOverwatch-like multiplayer and thepossible battle royale mode.

Call of Duty: Black Ops 4will launch on October 12 for PC, PS4, and Xbox One.
