BeamNG.drive

BeamNG.drive is a vehicle simulation video game developed and published by Bremen-based video game developer BeamNG GmbH. The game features soft-body physics, which simulates realistic handling and damage to vehicles. The game was initially released as a tech demo on 3 August 2013, and was made available on Steam Early Access for Microsoft Windows on 29 May 2015.
Development.
In 2011, some "Rigs of Rods" developers gathered to improve upon the open-source software with a new product. 
On 28 May 2012, BeamNG released a YouTube video titled "Revolutionary soft-body physics in CryEngine3". Originally, "BeamNG.drive" was to be based on CryEngine 3, but its use in a driving game uncovered numerous bugs, leading development to be rolled over to Torque 3D.
BeamNG's website, beamng.com, was opened on 8 May 2012 to deliver news of their development of the simulator.
The game was placed on an open vote on Steam Greenlight on 12 February 2014 and was greenlit eight days later.
On 29 May 2015, the game was released to Steam Early Access.
On 15 June 2018, BeamNG announced a partnership with Camshaft Software, Developers of "Automation", revealing the addition of an exporter feature that allows players to export vehicles made within "Automation" as fully driveable vehicles in "BeamNG.drive".
Gameplay.
"BeamNG.drive" features various gameplay modes and scenarios such as campaigns and a time trial mode. Campaigns are collections of small scenarios on specific themes (races, chases, stunts etc...), whereas in time trials, the player selects a vehicle, a level, a route, and competes against their own best time. In free roam, players can explore and experiment with levels, allowing them to operate, place and manipulate objects and vehicles within the level, but also change environmental properties such as gravity and wind. Players can utilize various objects ranging from road barriers to weapons to inflict damage on their vehicles.
The game implements soft-body physics to control both vehicle dynamics and collisions between objects and vehicles. 
Physics.
"BeamNG.drive" uses a real-time soft-body physics structure to simulate its vehicles. Algorithms have been written for the physics equations to be carried out. It relies heavily on coding in Lua, and uses packets of local data using the Lua network system while the game is running. The game's engine constantly calculates physics equations and problems in real-time during gameplay.
Vehicles in the game consist of a soft-body node-beam structure similar to those in "Rigs of Rods". The physics engine simulates a network of interconnected nodes and beams, which combine to form an invisible skeleton of a vehicle with realistic weights and masses. In terms of soft-body physics, vehicles realistically flex and deform as stresses to the skeleton, such as impacts from collisions, are applied. Aside from body deformation, various other types of damage is simulated such as degraded engine, detached doors and shattered windows. If a vehicle is severely damaged, the engine may fail, rendering the vehicle unusable; additionally, the vehicle will also fail from damage to the driveshaft, clutch, and other important components that can result in catastrophic failure to the vehicle. Also, tyres can be blown out and fuel tanks may explode after an excessive amount of collisions.
Reception.
Jack Stewart of BBC mentioned that "BeamNG.drive" "has received interest from the film industry to model vehicle stunts so that they can be prototyped and tested exhaustively – but cheaply – before a stunt driver smashes up a car on set." Polygon's Nick Robinson lauded the game's simulated physics and user-created content support, leading him to create a 38-episode video series for Polygon, "Car Boys", in which he and Griffin McElroy spotlighted new "BeamNG.drive" content each week. Automobile magazine praised the game for its diverse selection of vehicles and its realistic crash physics, saying that "the IIHS has nothing on BeamNG.drive."
