Video Game Bunker is a video game review show set in the post-apocalyptic aftermath of the Console Wars. It is hosted by Zero, played by TestZero. It primarily takes place from within the eponymous Video Game Bunker, though other areas are occasionally mentioned and seen.
Little is known about the host of the show. He wears a dust mask and sunglasses in order to keep his identity secret. He has an exceeding knowledge of video game history and design and is quick to speak his opinions about them. It is implied that he is slowly losing his sanity due to his constant isolation.
Commander Odo is Zero's stuffed walrus. Though he is never heard speak, Zero responds as if he does.
The Modular Artificial Intelligence Assistant is a computer AI that runs various functions of the Bunker. She spoke during an epilogue in episode 4, where she was voiced by Cassini Inuebony.
Video Game Bunker takes place in an undisclosed date sometime after the Console Wars. Little has been revealed about the Console Wars themselves, besides the three main factions involved. The Brotherhood of Sony, The Microsoft Army, and Mario's Children. Gamers who refused to join one of these factions were exiled and forced to live underground. Zero was one of those exiled, and he found refuge in his current undisclosed location.
