I doesn't seem to be possible. I cannot switch from Tactical to Classic. I really dislike such design decisions that might force you to restart a game after tens of hours. :(
When I look at the game difficulty options from main menu I only have option for explorer and classic. Do you have to beat the game once to unlock higher difficulty or something?
Is classic mode easier than vanilla version's diffuculties? or am i able to overcome the battle thanks to my previous experience :) Melee characters can attack from distance thanks to bombs now. Do you think it does ease the game?
URghhhhhhh I so regret going tactical. I had no idea I would be this bad ;(. It is such a shame cause I did so many quest stuff in the town before even venturing out.... :(
