Like many other games in the soulslike genre, Lies of P has a number of NPC questlines that run throughout the entire game, including one centered on a Stalker known as Black Cat – and although in most cases these quests are less obtuse than others in the genre, the different outcomes of each quest can still be unclear. As each NPC quest can only be completed in one way per playthrough of the game, decisions that yield different rewards or story outcomes can be especially important to consider, especially since certain decisions can have effects outside their individual storylines.
