In the 6th release of Season 3, this pack includes 10 Boost Gems exclusively for Street Fighter characters. These Gems activate as you are on the defensive but looking for your chance to strike. Note: If you would like to see the effects of the Gems individually before purchase, you can view them in-game from the Gem List within the Store, or from Gem Unit in the Customize menu. This add-on is exclusive content for STREET FIGHTER X TEKKEN. The effects of the Gems may be subject to change.
