The Call Of Duty-r- Modern Warfare 3 Single-player Demo Instant

I notice you’ve asked me to based on the title: “The Call of Duty‑R‑ Modern Warfare 3 Single‑Player Demo” However, that phrase is not an academic or industry paper title I can locate. It looks more like a game version string, a filename, or a retail demo descriptor (possibly from early 2010s press builds or store kiosks).
