Excellent news, Commander! You can now obtain Equipment Packs for your Champion at the Black Market! Each Pack contains special Crates with Equipment that will improve the offense or defense of your Infantry, Armored Corps, Artillery, and/or Air Forces! Each Pack also contains exactly the Keys you need to open the Crates you get!
STRATCOM has added a corresponding button to your Champion's Inventory interface that will bring you to a place in the Black Market where you can view all the Packs available to you. Or, if you prefer, you can go directly to the Black Market, open the “Champion” Tab then, in the “Crates” Tab, purchase the Packs you want. Keep in mind that Packs differ from one another and accordingly affect different Units. Some more advanced Packs will require you to research certain Technologies in order to purchase them.
