The Tekken card game announced in January is now available, marking the series' first move into the free-to-play market. Tekken Card Tournament, a CCG based on the popular fighting franchise, is now available. While initially only announced for iOS, with other platforms a possibility, it has launched on PC and Android as well.
As a free-to-play game, of course, it offers in-app purchases. You can earn your way to currency to buy booster packs, or purchase heaping sums of it at various tiers. Booster packs cost 120-320 credits. The Bank sells 50c (99 cents), 120c ($1.99) 250c ($3.99), and so on. The most expensive pack is the Vault, which grants 10,500 credits (enough for about 90 of the low-tier packs) for $99.99. Namco also promises physical booster packs coming this summer, which will let you scan to add them to your digital collection and play with augmented reality functions.
