Alicia, Welkin, and Welkin’s sister Isara Gunther are playable characters in Valkyria Chronicles 2.
If you have a Valkyria Chronicles save file on your PlayStation 3 you can unlock Isara immediately. We’re guessing you’re going to need a Japan-region coded save file to do this, but don’t worry you can still get Isara another way. Sega will post a password to unlock her at a later date.
Maximilian, you know, from the Empire can also be an ally. You can get him via a password on the official Valkyria Chronicles 2 page on February 18.
Faldio Landzaat also makes an appearance in the sequel. You can access him before Maximillian also from a password Sega plans to release on February 4.
Here’s some artwork for the three cameo characters. Valkyria Chronicles 2 is still on track for January 21.
