So Bungie, I have been thinking about possibilities for multiple games, when I thought about some DLC content for Destiny. I believe that you should team up with Valve to create a Portal Easter Egg DLC. You should be on Earth in a seperate zone, and eventually find the Aperture labratrory complex, and be able to explore. After beating the main core, you should find a portal gun, that can be used as a super with the same functions as the original game. I think all fans would like to see this, as it would make for great DLC.
