Bosses are as hard in Overture as they are in Lies of P's base game, if not harder, but one key design choice makes them a lot more palatable.
Unlike the base game, Lies of P: Overture features a unique boss fight that indulges fully in the concept of a 'puppet' and its 'puppeteer.'
Cross the bounds of time in Lies of P: Overture
They were waiting in the dark. Now they rise. Face fierce new bosses and carve your path through the shadows of Krat’s history. Lies of P: Overture is a brutal new expansion to the acclaimed soulslike action RPG.
Game Rant tours the Krat Zoo in Lies of P: Overture's opening hour and dives into the Battle Memories boss fight mode with some all-new gear.
Very excited for this - it sounds like a very worthy follow-up to the excellent main game.
