This game is pretty amazing one of the best I've played
Is it possible to make a instant kill cheat for the vanguard ?
and maybe a unlock all characters button ?
and also a level up 5 levels cheat?
The entire vanguard battle system is optional (apart from unlocking Lind). There is no point in making cheats for a system that, if the person has no interest in playing it, he can simply not play it without losing content.
The future war system will have two different options for battles. Either you fight with the vanguards, or if you don't want that, there will be the option to solve the battles in a story mode with dialogs and choices.
Level 3 is requires for some vanguards for their CG scenes, but you can quickly farm that in the arena or academy without having to go to battle.
