The Barotrauma ecosystem comprises interconnected upstream, midstream, and downstream layers that collectively enable the development, delivery, and utilization of the simulation platform. Upstream participants supply core software engines, physics libraries, and hardware components that form the technical foundation. Midstream actors integrate these inputs through development studios, platform providers, and system integrators that assemble gameplay mechanics, multiplayer networking, and mod‑support frameworks. Downstream channels—digital distribution platforms, resellers, and community marketplaces—bring the finished product to end users, ranging from individual gamers to institutional training programs. Value is generated by transforming raw code and hardware into immersive experiences, captured through licensing, subscription, and ancillary services.
