MEDIUM

Why flagged The PKGBUILD downloads a prebuilt x86 binary (a Unity game executable) from the official game's own domain (typefighters.com) via a PHP delivery script. The host is the upstream vendor's own site, not a personal or third-party host, so this is analogous to many other game packages that use dynamic download URLs. A sha256 checksum is present and pins the specific archive. The main concern is that a PHP script (sendfile.php?id=23) could theoretically serve different content without changing the URL, but the checksum mitigates silent substitution at build time. The binary itself (Typefighters.x86 + Unity data) is executed code from a closed-source game, which is the standard medium-risk profile for -bin packages. There is no obfuscation, no exfiltration, and no piracy concern (described as a free version). Overall this is a legitimate but medium-risk pattern: a prebuilt binary installed from a vendor-controlled dynamic URL with a checksum.
