1. Gameplay

The player is the driver of a bus of Berliner Verkehrsbetriebe. It is double-decker bus of the series MAN SD 200 and MAN SD 202 as well as low floor buses of the type MAN NL 202 and MAN NG 272 with the original logos of the manufacturer. Here, vehicles of different years were replicated with different vehicle advertising. Can be driven on the line 92/137 and the section 92E between Falkensee / Freudstraße and Heerstraße city boundary / Hahneberg, BVG routes 5 / 5E / 5N / 130 / N30 between Spandau Psychiatric Hospital and U-Bahn station Ruhleben and part of BVG route 13N / N33 between Heerstraße Stadtgrenze / Hahneberg and U-Bahnhof Rathaus Spandau. In addition to driving itself, the ticket sale and passenger comfort is also simulated. In addition, the player can ride in buses of AI traffic.

With the Map Editor included in the game scope, it is possible to create your own maps and lines for OMSI. Also own bus models can be integrated into the game. Interaction among objects is based on a stack machine scripting language resembling assembler.

2. Further Development

Since the end of 2011, work has been done on joint physics for the simulator. With the MAN NG 272, an articulated bus has entered OMSI for the first time. As this differs little from the low-floor bus apart from the joint MAN NL 202, it was also released with the next OMSI version. On February 23, 2012, the developers announced the official further construction of the Spandau card included in the delivery. This includes the former line 5 from the mental hospital Spandau to the subway station Ruhleben. Furthermore, the map Berlin-Spandau in different periods (from 1986 to 1994) playable. In addition to these fundamental changes, other variants of the existing models SD 200 and 202 were added; In addition, there is now a chronology function that simulates events like the collapse of the Berlin Wall. The further development officially appeared on December 12, 2013 under the name OMSI 2. This version also improved the performance.

On September 15, 2014, it was announced that MR Software will disband and that Marcel Kuhnt will no longer work with Rüdiger Hülsmann in the future.^[1] On October 10, 2015, Marcel Kuhnt announced that under the name Oriolus Software^[2] has begun development of LOTUS, a successor to OMSI. In two publication steps, it will initially be possible to simulate buses and trams, and later also U- and S-Bahn trains. Since then, the developers regularly publish new information on the development on their Facebook page.
