Sega has even more Valkyria Chronicles 2 tie-ins, but these aren’t as off the wall as the Pizza Hut shield in Phantasy Star Portable 2. Players can obtain Sonic, Bayonetta, and Hatsune Miku decals. Passwords to access these tank stamps will be posted on the Valkyria Chronicles 2 home page.
Finally, there are three special decals.
Some Japan-only games like Answer x Answer and Border Break are featured. Will make the cut for the English version of Valkyria Chronicles 2 or will Sega replace them with stuff more popular on this side of the pond like Madworld and The House of the Dead.
