In the beginning of the game we get a good look at the outside of Sevastopol and aside from the docking mechanism being too busted for the Torrens to dock, there’s debris all around the station. I haven’t finished the game yet, but I’m on mission 13 and have yet to find any email or recording with an indication of something having collided with the station, and while xenomorphs can certainly wreak havoc within the station, they don’t do anything that would really cause that kind of damage to the hull, certainly not on the exterior.

Also, what was the explosion that occurred while Samuels, Taylor, and Ripley are space walking over to the station? Do we ever find out exactly what caused that?
