Is there a way i can unzip the file with just an Oculus Quest 2? I dont really have a good cable to connect it to any of my devices with and really want to play this badly.
No. This game is designed for Windows PC, using the Quest as just a headset. The Quest 2 (as with most other headsets AFAIK) all use a custom operating system based on Android, which can't run Windows applications directly.
You could try using a WiFi connection, assuming your WiFi is good enough. Otherwise, you're just going to break down and buy a cable. I'm using a relatively inexpensive 12-foot cable I ordered online and that's been working pretty good so far (I think it cost about $15, but I've had it for a while so I don't remember anymore)
