sren17 is part of a community-made arg (alternate reality game) and ghost lore built around gorilla tag, not something official in the real game files. it’s tied into the larger pbbv mythos that spread through videos and reddit posts starting around 2021.
in the arg, sren17 is essentially the “siren” from forest — a tall siren object in the map — personified or imagined as an entity. the name sren is short for siren in that context.
some lore pages and fans claim sren17 embodies the radio connection form of the ghost “pbbv” inside the siren, with creepy sounds or distorted radio-like audio allegedly playing. this is part of the arg’s storytelling, not a real ghost in the actual game.
lore also says that joining specific ghost codes like SREN17 or PBBV can put you into an alternate “replica” version of gorilla tag where the siren/pbbv appears, sometimes with strange voices or effects — again, these are part of the arg and not present in the real official game.
the arg mixes creepy audio, coded messages, and fictional behavior (banning players, replacing connections, deep voices) to make it feel like a hidden horror element, but it’s all fan-created lore and rumors that spread through youtube, reddit, and community wikis.
