EDIT: So it turns out that, as Backflip_into_a_star pointed out in the comments, this is just my fighter hangar. Sorry everyone…
Ok, so I was playing ED Odyssey last night, and I was driving around on an icy world. Eventually I got a connection error which sent me back to the main menu, but it was late anyways so I decided to get some sleep. The next day, I boot up Odyssey again, but my SRV was weirdly glitched into the SRV bay of my Krait. It was open, but since I had clipped into the ship, I was just floating there. I decided to try and move around to get unstuck… and reverse through the back of the loading bay INTO A ROOM. Fully textured and modeled, and pretty high poly too. It appears to be some kind of cargo bay, with two small doors at the front and a large one at the back. Just to check, I searched up "Krait MKII interior" in case anyone had seen this already. Nothing. Just images of the cockpit area and general layout concepts. Frontier must be planning something big, as it seems they've at least started to actually model the ship interiors. If anybody has any information regarding this, please share it in the comments. This opens up a whole new world of possibilities for the future.
