In Call of Duty: Black Ops 3, you have the option to customize your weapon, perks, and equipment which are called as Perk 10 System. To Bend this system, we have Wildcards which allow to max out your load. Here is everything you need to know about the Wildcards in CoD: Black Ops 3.
In Perk 10 System, you are only allowed to carry 2 attachments for a Primary weapon, 1 for Secondary weapon and one for lethal equipment which makes it very restricted for a player to go out for a Multiplayer Map with such limited loadout. So they have a come up with something very special called the Wildcards. Wildcards help to break the Perk 10 System(depending on the card) and allow you to carry 2 primary weapons and more than 3 perks at one loadout.
Only make use of these Wildcards when you think you are fully ready to dominate the Multiplayer Map or else it will counter back putting you in a risk to survive the multiplayer battles. So it's very important to know when to use these Wildcards in your battle with two primary weapons, but these also means that you lose your chance to carry a secondary weapon and launchers. Check out the Below list of Wildcards and what they have to offer you against the Perk 10 System.
Greed
Greed mainly consists of 3 unique Wildcard categories and each Wildcard takes a second perk. So plan accordingly which park slot will carry what, match up a good combination to travel and survive in your Battle. Don't be greedy, just be Smart and take your time.
OverKill
If your preference is more on the primary weapons rather than secondary then the OverKill cards are all that you need. The Overkill card will allow you to replace the secondary weapon slot with primary and hence you can now carry more than one primary at a time.
Primary Gunfighter
This Wildcard for players would be a dream come true as they can now break all the limits of two primary attachments to five for a single weapon. Isn't that great?
Secondary Gunfighter
This Wildcard will allow you to add another attachment to the secondary weapon.
Tactician
Tactician Wildcard will allow you to replace your Lethal slot with a second Tactician slot. For Example, you can swap a lethal grenade with any tactical grenade or anything else.
Danger Close
Not happy with just one lethal equipment slot? Use the Danger Close Wildcard and take a second lethal equipment with you.
