The first time a raven appeared having to do with the game was in the most well-known concept art of the Neighbor holding a shovel and standing before a grave. A raven is obviously seen standing on its edge. Another one also appears perched on a branch in the background. Two also appear in the concept art of the Neighbor standing in his kitchen holding a butcher knife, staring at whatever he is cutting.
There are several raven paintings in Neighbor's house.
At the beginning of the game, when the main character moves to his new house, the raven is seen to have stolen the house key from under a stone. In order for the raven to release the key from its beak, it is necessary to throw a stone at it.
The same as in Alpha 1.5, but now Raven has sounds and it disappears after the main character throws a stone at him.
