Jakejames Lugo of The Koalition writes: Paranautical Activity is a first-person shooter that has procedurally generated rooms filled with monsters to kill but does very little else to be interesting or fun to play. While it borrows a lot of its visuals from games like Minecraft, it has a very lackluster approach to first-person shooting within its horror-like setting. Beyond that is nothing more than a very hollow experience that is both bland and buggy. Games like Paranautical Activity are meant to be played through multiple times for a different experience each time you do so, but it can be very difficult to do so when what is there isnt fun enough to justify diving back in again.
