Looks like a typical mitm attack, which confuses me a bit, don't the developers use something like tls or dtls to protect their communications? The most recent game I analysed was helldivers 2, which uses dtls. i would have thought that would be fairly common knowledge.

That's the issue - they don't! But even games like Helldivers 2 have had silly vulnerabilities (just not RCE) - see https://helldivers.io/freesupercredits for some examples.
