It Comes from Above(2022)

A young man lives and works in an abandoned bunker in a deserted post-Soviet interzone of industrial ruin. When he's not drinking, bailing floodwater or making techno beats, he's playing a video game that eerily mirrors his post-apocalyptic surroundings—hovering UFO included. Shown in complete isolation, he is the hero, the shooter and the zombie of his own moody game.
