After we witness of the rare and exclusive preview of Grognok level editor tools from GDC, would we be able to try it out and see what creativity ideas we can create using Bungie's in-house tools? The benefit for using it is that we would be able to work for Bungie the most easiest way as possible, and be able to support their new adventure world of Destiny. As well as demonstration of how we use the tools for digital portfolio!
No. If we want to work for Bungie, and use their master-crafted tools, we need to earn the privilege.
