How many endings does DreadOut have?
There are only two endings so don’t you worry. For Ira Phone Number, it is an achievement. Ira has been killed and didn’t receive voicemail from her. In the True Ending of the game, if Linda manages to save Ira from the Third Sister, you can hear that Linda is actually listening to Ira’s voicemail. If Linda fails to save Ira, there will be sad music playing instead. Entry about her never appears in Ghostpedia.
