Horseback Mountain is a case featured in Criminal Case as the one-hundred thirty-second case of the game. It is the seventeenth case of the game's World Edition (Season 3) and also the fifth case to take place in Eurasia.
After the Trans-Siberian incident, the Bureau finally arrived in Mongolia. Carmen and the player looked for clues about SOMBRA's satellite in Mount Khan, where they found the partially sliced body of satellite engineer Andrei Beloglazov.
During the investigation, Elliot found SOMBRA's satellite factory below a statue in Mount Khan. Later on, Asal and Anya Ivanova threatened to shoot each other inside the factory. Despite the tensions, the team gathered enough evidence to arrest horse breeder Tsetseg for the murder.
Tsetseg initially denied killing Andrei but soon admitted to the crime. She also revealed herself as a hitwoman, and said that SOMBRA paid her to kill Andrei. She fulfilled their orders by partially slicing Andrei with a saber. As she refused to keep talking about SOMBRA, Judge Adaku sentenced her to 30 years in jail.
After the trial, Carmen and the player looked for clues about the satellite's whereabouts at the factory, where they found COSMORUS swipe cards. Per Elliot, the cards were counterfeit, and SOMBRA would use them to access one of the launch sites disguised as COSMORUS employees. Yelena Tereshkova, a frustrated cosmonaut, revealed that Andrei had had an argument about shipments in Mount Khan, where they found a delivery slip which showed that the satellite was finished and shipped to Kazakhstan.
Meanwhile, Asal told Jack and the player to investigate Anya, whom she suspected of. In a Mongolian restaurant, they found a microfilm which (per Elliot) contained a message in which the MGB told Anya that her investigation in Mongolia was unauthorized. Anya revealed she had been investigating to take SOMBRA down.
As Natasha made clear she would not help the Bureau any longer, Elliot hacked into COSMORUS' security systems and got them high-level clearance to the launch site in Kazakhstan, where they headed to stop the satellite launch.
