"A horror game on a boat"
Monstrum will let you know what real fear is by making you the only survivor of an accident that took place on a ship that was sailing at sea. Monsters keep appearing on the boat that will make your life impossible.
Every Monstrum creature has its own abilities, but none of them is able to move towards you without making noise. You will have to remain very attentive to try to anticipate their progress and choose another way so as not to cross with them, which would involve a persecution that would probably end badly and suffer an anguished death. At no time will you cease to be stressed, as a failure implies having to start the game again.
Any action to avoid monsters must be carried out at the right time, from blocking certain accesses to deceiving creatures by throwing an object. At the same time that you try to get out of the ship you will have to collect the necessary elements, which will not be easy for you considering that all the form and disposition of the ship changes when starting a new game of Monstrum. So, you'll always have to deal with new scenarios that coincide in being extremely gloomy.
