Horizon Beam: Los Santos

Horizon Beam: Los Santos brings Forza Horizon 4's iconic car roster and BeamNG.drive's soft-body JBeam crash physics into Grand Theft Auto V Legacy (Story Mode).

What each game brings (from your own installed copies)

• Grand Theft Auto V Legacy (Host, Story Mode only): The streets, highways, and mountain roads of Los Santos, plus five Horizon Speed Traps and Crash Lab barriers across the city.
• Forza Horizon 4 (Companion): Reads your installed Media/Cars/*.zip, Media/Audio/EngineSynth/PC/*.zip, and AppxBlockMap.xml / .modelbin descriptors for 8 iconic Forza cars (2016 Acura NSX, 2012 Lamborghini Aventador J, 2014 Porsche 918 Spyder, 2017 Nissan GT-R, 2016 Ford Focus RS RX, 1969 Dodge Charger R/T, 1998 Subaru Impreza 22B-STi, 2018 Bugatti Chiron) with a live Horizon digital telemetry & PI class HUD.
• BeamNG.drive (Companion): Reads your installed content/vehicles/*.zip .jbeam node-beam structures and combustion engine torque curves (sbr, scintilla, bolide, etkc, vivace, barstow, sunburst2, bx). Every collision in Los Santos calculates real-time node-beam stress against beamDeform and beamStrength, bending the chassis wireframe, pulling the steering rack off-center, collapsing suspension wishbones, and reducing engine torque.

Controls

• F8: Open / cycle the Forza Horizon 4 Garage & Car Selector ([ / ] or Up/Down arrows to switch cars, Enter to apply).
• F9: Repair all deformed and fractured JBeam nodes and beams back to factory spec.
• F10: Trigger a calibrated BeamNG Crash Lab impact test on the active chassis.

GTA V Story Mode only (launched with Rockstar's -nobattleye Story Mode flag).
