Hello Neighbor 2offers two extra DLCs for players who aren’t ready to let go of the game yet and allows them further investigate Raven Brooks’ mysterious properties. For example, the town’s school in Back to School DLC and the library inHello Neighbor 2Late Fees DLC.
The Back to School DLC offers players a variety of additional puzzles to solve, some of which are easier to solve than others. The chemistry lab puzzle is one of them, since it doesn’t require knowledge in the science field to solve it. However, finding the riddle’s necessities is not so easy, as it needs a few items that are behind a frozen door inHello Neighbor 2.
