The video showcases all the endings that the player might get in a video game, S.T.A.L.K.E.R. Shadow of Chernobyl.
S.T.A.L.K.E.R. Shadow of Chernobyl presents players with decisions that the player might have to make, in order to advance. With your reputation being bad or good, the faction affiliation you might have or choose to pick, or destroy the leaders of mention factions, you are sure to get one of the seven endings. Some of them are straight up bad with few bittersweet.
Like said before, there are, overall, seven endings, yet, only one is canonical, all of the other being “false”.
All but one of the “false” endings appear when player approaches the Wish Granter, of the main mysteries in S.T.A.L.K.E.R. Shadow of Chernobyl. Depending on your choices in the game, you might get a different ending. Though all of the wishes, as the video shows, are granted, all of them are granted with ironical sense. For example, when Strelok, the protagonist of the Shadow of Chernobyl, asks for immortality, the wish granter makes Strelok into a metal statue. Nor a living, nor a dead being.
Another “false” ending requires talking to the C-Consciousness and accepting its offer to join it. Conversely, if you decline it, you’ll get the canonical ending of the S.T.A.L.K.E.R. Shadow of Chernobyl ending.
