1 month after you posted the PC version isn't a thing. So, I assume the want to keep HiBow for the Quest and Airranger for PC.
See i dont understand their thinking, why not have one game with cross compatability,so they can have a larger audience for multiplayer. With VR multiplayer always being an issue due to lower player base (in comparison to flat screen multiplayer), why split the audience. More maps, nurture the community and the game would thrive (in my opinion). Its just such a wasted opportunity.
