Last weekend (Saturday 15 and Sunday 16 of December) several stores in different Japanese cities were holding a special Metal Gear Rising Revengeance promotion. Customers could try out the demo in store, and receive a special flyer or even a t-shirt if they performed well in the game. The Japanese Kojima Productions Blog as well as KP staff member Tsubayaki Jiroo posted some photos of the event online.
These are the promotional items people could obtain.
