Granny 2

Granny 2 doubles the original's single stalking threat into two, Granny and Grandpa patrol independently, which means a route that's safe from one can walk you straight into the other, and tracking both their positions at once is the real difficulty jump over the first game.

Because the two threats don't coordinate but do overlap unpredictably, clearing a room fully before moving to the next rather than darting between areas tends to avoid getting pincered between them. Puzzle items are shared progress toward the same escape regardless of which pursuer is nearby, so it's often safer to retreat and wait out one patrol than to grab an item while both are converging on your position. Granny is the original single-pursuer version of this same stalking-horror format.
