Co-op
Players who bring up Co-op mostly praise it.
145 of 300 sampled reviews raised it
You're playing a repetitive game that has a lot of potential for a co-op survival featuring zombies.
Gameplay
Players who bring up Gameplay mostly praise it.
87 of 300 sampled reviews raised it
The sound track, ambiance and mechanics are very inspired by old age survivor horrors, and puts a twist by not plugging zombies but adding supernatural and haunting elements.
Combat
Players who bring up Combat mostly praise it.
47 of 300 sampled reviews raised it
The combat is very "easy to pick up, hard to master" especially in more perilous situations.
Multiplayer
Players who bring up Multiplayer mostly praise it.
28 of 300 sampled reviews raised it
In conclusion, I highly recommend it, especially if you enjoy games like RE, rougelites, and/or multiplayer games.
Graphics
Players who bring up Graphics mostly praise it.
27 of 300 sampled reviews raised it
Sound design is alright (some like reloading sounds like stock sounds and are awful), there should be more voice options to choose from, the art style is neat (though there could be much more pixel character designs to choose from- as of now there is only 3 body types, 5 head types, and 8~ colors if I remember right).
Audio
Players who bring up Audio mostly praise it.
19 of 300 sampled reviews raised it
Drawing inspiration from early entries in the Resident Evil franchise, WMO does an excellent job of setting up tension and horror vibes through its game play, environments, and sound design.
