OMSI 2 is a bus simulation game developed by German studio M-R Software GbR and published by Aerosoft. It has only been available on Microsoft Windows through Steam, since the game's release, December 11, 2013.
It is the successor to OMSI: The Bus Simulator, released in 2011, first published by Aerosoft on DVD. M-R Software has since dissolved but DLC continues to be produced.
Gameplay The base game comes with two maps, both based in Germany, and one bus manufacturer, MAN, offering buses such as the MAN NL202, SD200 and SD202. The Berlin-Spandau map is one of the two maps, recreated on a 1:1 scale, and is set from 1986 to 1994. Grundorf, the other map OMSI offers, comes with a small, fictional map, and only one short route. It is also the map used for the tutorials.
Reception
Writing for Rock Paper Shotgun, Tim Stone remarked positively on the game's recreated environments, described it as more accessible than the first, and commented positively on newly added buses, routes, and environmental elements. However, Stone described it as "bustled out of the door before it was good and ready", commenting that performance and stability issues made the game hard to recommend in its released state. Multiplayer.its Simone Tagliaferri described the game as a successful simulation, complimenting its historical accuracy and regarding it as exploring an interesting time period around the fall of the Berlin Wall, but also as extremely demanding on systems and plagued by crashes, concluding that it was a unique simulator but one that was difficult to recommend.
Legacy and successors Despite the game being originally marketed as a German bus simulator; it has gained a significant international following from various bus communities with the most prominent being from the United Kingdom, Hong Kong and Central Europe.
Within parts of the English-speaking community the game is often informally pronounced as: "Om-see" as opposed to spelling out the games name: "O-M-S-I". This pronunciation has been often accredited to the popularity of NerdCubed's videos where he refers to the game as "Om-see" whereas many other YouTubers at the time didn't use this name.
As there is no official pronunciation, the term "Om-see" has become the de-facto name within multiple communities.
openOMSI
openOMSI is an open-source complete recreation of OMSI 2; aiming to port the game over to 64-bit by reverse engineering the original game's code into the programming language Rust.https://turbo-devv.github.io/openOMSI/
It brought many bug fixes and technical enhancements to the game, like making it possible to run OMSI 2 on multiple platforms including Mac, Linux, and Android. Support for DirectX 12 and OpenGL were also implemented which allowed for more realistic graphic presets to be used.
Many new features were added that were previously not possible in the former game such as: users being able to walk around maps on foot as well as multiplayer functionality.
Despite the port being written in a new coding language, users are required to have the original OMSI 2 installed.
As of 2026, it is unknown whether or not Aerosoft is aware of the port's existence.
DLC (downloadable content) As the two owners, Marcel Kuhnt and Rüdiger Hülsmann, no longer work on OMSI, developers publish buses and maps through Aerosoft which then becomes DLC on Steam. DLC can vary from buses, to maps, or even utility and tools. +List of all DLC ever released on Steam as of DLC nameRelease dateType of DLCDevelopersOMSI 2 Add-on AI-Articulated Bus for Vienna21 July 2014AI BusViewApp, MR-Software GbROMSI 2 Add-on City Bus O30513 August 2014Bus, MapMR-Software GbR, Rolf WestphalenOMSI 2 Add-on Hamburg11 September 2014MapDarius Bode, Barbara BodeOMSI 2 Add-on Vienna15 October 2014ViewAppOMSI 2 Add-on Three Generations3 December 2014BusDarius BodeOMSI 2 Add-on Chicago Downtown17 June 2015MapOMSI 2 Add-on Berlin X109 October 2015Halycon MediaOMSI 2 Add-on Vienna 1 -
