I am about to finish off the game. I still have challenges to do. I heard that the best time to do that is in NG+ on Prince of Darkness difficulty since you get the achievement. If so I start NG+ do I have to collect the shards again to unlock them or is it unlocked straight away when I release chupacabras?
Actually you can do the challenges BEFORE NG+ just bump the diff up to PoD. this also makes things a little easier. --- We each play out the parts Fate has written for us. Free will is an Illusion. - Kain I Pray to no One! Nor will I be prayed to! - Asura
