Since "Beta 0.7" isn't an official version of GTA V (and is likely a fan-made mod, a concept, or a throwback to the early development days), I have created a few options for you depending on the context you need.
Do not release this build to the public. Recover assets from the cut "Electro-Choc" station for potential DLC. Prioritize fixing the water physics crash. gta v beta 0.7
