Weeeeeeelllllllllllllllll. I kinda needed a place to post this but it's just an idea. I think that Sandbox will be outdoors and bigger than Foundry. That's just from the name. But if you look at the achievement for finding the skull on Sandbox, that it will be made with forge in mind, attempting to be the new Foundry. Now you shall post on what you think it might be.
well based off of bungies recent weekly updates they had a picture drawn with the skill of a third grader that was supposively a drawing of sandbox. It look almost exactly like sandtrap except at night time. Most likely just with more forging capabilities. Theres another thread which is more in-depth in this forums so u can look that up if youd like.
This should be in regular Halo discussion, not forge discussion. Also, threads like these have been done many times, so I suggest you take a look around the forums before posting a thread like this. Cheers.
