Games like HL:AL and Pistol Whip implement API's (Or similar) that anyone can use to receive gun-context events on the PC running the game - like this-type-of-gun-fired, mag empty, etc. This allows people to write code that send these events to DIY force feedback boards on gunstocks. Other games like Pavlov implement proprietary SDK's from companies like ProTubeVR, and you cannot access this data. Please consider the former approach, and enable the community to build their own solutions to force feedback devices using game context accurate events to drive it! Great game overall team.
