If you are referring to a game in the "Call of Duty" series that allows players to unlock wildcards (which modify loadout options), it might be similar to mechanics introduced in previous titles like "Call of Duty: Black Ops Cold War COD BO6 Boosting."

In games like "Black Ops Cold War," wildcards are typically unlocked through multiplayer progression. Here’s a general way to unlock wildcards in Call of Duty games that have utilized this mechanic:

1. Generally, wildcards are unlocked as you level up your character or are tied to certain ranks in multiplayer mode. Play multiplayer matches to gain experience points (XP).

2. Some wildcards may be unlocked by completing specific challenges. This can include achievements such as getting a certain number of kills with specific weapons, completing objectives, or playing certain game modes.

3.In the game’s Create-a-Class menu, there is typically a tab for wildcards where you can see which ones are available and what you need to do to unlock them.

4. If the game allows, try using different weapons and perks to see if there are hidden challenges or objectives that, when completed, might unlock additional wildcards.

5. If a specific game has received updates or events that influence wildcards, keep an eye on official "Call of Duty" communications, including social media or community announcements.

To get the exact gameplay mechanics for a specific title, it’s best to check the official "Call of Duty" resources, forums, or dedicated gaming guides after the game's release (if it exists beyond my last update buy cod bo6 weapon Leveling). Depending on the title, the requirements for unlocking wildcards may vary.
