Last night, while playing a patrol mission with a team, my ship was taking heavy damage. Being near a starbase, I did a dive to get under the "mushroom" top, all while getting hammered by enemy weapons. When I was finally below the top, the ships stopped firing as expected, and it was a game of cat and mouse with one enemy ship that tried to skirt around the starbase and dip below it.
That whole moment was definitely a lot of fun and very cinematic to watch. Unfortunately, within a minute, enemies above the starbase starting firing again on me, and somehow their weapons were able to go through the starbase itself. I'm hoping this is just a bug. I've used asteroids and other objects as cover before, and it definitely provides for more enjoyable battles than just the typical broadsides.
