GTA Myths Wiki

The Maintenance Tunnels are a mythical location located in downtown Los Santos, with two entrances. One at the far end of the Los Santos water reservoir and one located beneath an underpass. The tunnels are used during the first heist as an escape route. 


The Maintenance Tunnel myth involves a ghost, who is thought to be haunting the tunnels. Players have reported hearing voices and strange noises from an unknown source while traveling within the area.

In one part of the tunnels, near the unfinished station, a demonic, shrill-sounding laughter can be heard lightly echoing. If the player sticks around in the area for a while longer, it can be heard once again. The sound is one of the many scripted ambiances that can be heard in the sewer. The other being the sound of alligators coming from blocked-off sewer pipes. These have been confirmed by an audio file with the name sewer_gator that contains the same sounds from the tunnel. Multiple players and myth hunters have confirmed this, and as of yet, no explanation has been given. This has rumored to be related to Ratman due to the high pitch of the laughter. This could be an Easter egg by Rockstar, poking fun at the endless stream of Ratman reports in Grand Theft Auto IV.

A strange breathing noise occurs whenever the player enters the water reservoir entrance to the tunnels and starts down inside. It always happens, but is hard to hear the noise, so the volume must be turned up. This occurs in both GTA V and GTA Online. Some believe it may be Ratman or a ghost's breathing as they are watching the player.

Ratman is also rumored to inhabit the tunnels and sewers due to the environment in the tunnels, and the fact it is a major location for normal rats. There has been no proof of this though, and it is most likely a continuation of the Grand Theft Auto IV myth.

Some players also claim of other odd occurrences, such as a strange beating noise, most likely a metro passing, and even reports of health slowly decreasing, similar to Panic in the Woods.[1]

Sewer Killer is an urban legend that revolves around an unidentified overweight man wearing an stereotypical hillbilly suit with an also stereotypical hillbilly hairstyle and mustache who reportedly stalks players and attempts to kill them if spotted. So far, he has only been documented in Grand Theft Auto Online, but his presence could extend to Grand Theft Auto V. It is possible he is merely an player or group of players pranking whoever wanders into the tunnels or also could just be an glitched maintenance worker NPC, but it is not impossible that the mythical Sewer Killer really is an decrepit murderer waiting for someone to enter the tunnels so he can strike.
