It was made clear earlier this year that every Xbox One would have the capability of becoming a development kit, making it easier for aspiring hobbyists to create for the platform without having to fork out the cash for dedicated hardware. What you might not know is that this functionality doesn't need to be patched in -- you can activate it right now, if you're willing to risk stuffing up your console.
As Reddit user "LiamHing" found out, all one has to do is enter the following combination of buttons while viewing the "System" menu:
Left bumper, right bumper, left trigger, right trigger
After which a new menu option will appear called "Developer".
However, an Xbox One developer weighed in on the conversation to warn users of turning this feature on willy-nilly, as entering incorrect information in the "Sandbox ID" field (visible in the picture above) can put your console into a "boot loop".
This is not a good thing.
The developer also mentioned that issues like "privacy, security [and] stability" would need to be resolved before "anyone and everyone [can] sideload an app onto their box".
So what can you do for now? Well, that depends on how brave you're feeling. If you do decide to go ahead and fiddle with the developer settings, please don't blame us if your console explodes or does something else terribly terrible.
