The cards are for that other side game in the menu. I got a ton of them because I preordered the deluxe version. They're not for the main game.Uncharted just felt like a cover shooter with climbing. Story was way better than Tomb Raider but Tomb Raider gameplay is definitely more fun IMO.
Played almost 4 hours, there are more things added like crafting on the fly, a bigger focus on stealth, hiding up in trees etc.
Anyone have an idea what the cards do though? Or how to equip/unequip them?
