SEGA has announced that it will release exclusive add-on missions for Valkyria Chronicles II as an incentive for pre-ordering the strategy RPG.
The missions will be available as a free PSN download when the game is released for PSP on 3rd September in Europe.
There missions take the form of exercises against two rival classes, one requiring you to destroy all enemies, the other to take over an encampment. The SEGA blog has the details.
Valkyria Chronicles II is the sequel to the excellent PS3 original. It adds co-op and competitive multiplayer to the mix of turn-based strategy, teen soap opera, levelling and baroque, fantasy First World War fashions.
