Injustice: Gods Among Us, also known as Injustice: The Mighty Among Us, mixes the best elements of collectible card battle games with fighting games, creating a new genre that has never been done before and promises quite a bit of replay value due to the collection element. The three tiers of cards are bronze, silver and gold cards. Bronze fighter cards are the most common, but the least powerful. Silver and gold cards are far more rare but far more powerful, so naturally those are the ones you want to try to get. Read on to find out how to get more of them!
The main way to get more silver and gold cards, of course, is to buy card packs for them. The bronze booster card pack will earn you bronze cards, while the silver booster pack will earn you a silver card, and the gold booster pack will earn you a gold card. In addition, the starter pack, if you choose to buy that, will earn you three different silver cards.
You can also buy each one of the silver cards individually, and ditto with the gold cards, although they will be more expensive than if you just get them in a booster pack. To do this, go to the character tab in the card purchasing screen and scroll to the right, past all of the bronze cards. First you will hit the silver cards, and then you will hit the gold cards. The more expensive they are, the more powerful they are. It’s more expensive to pick out each card individually rather than randomly in the booster packs.
You can win gold and silver cards as a reward for beating battles. Most of the time you will only win bronze cards, but the harder the battle gets, and when you beat the bonus battles at the end of a particular round of fighting, or the boss battles in each stage, you’ll earn better rewards.
