One thing that I loved in the Order expansion is the asteroids. It would find very cool to see an other visual effect of that type for the next.
What ? I don’t know. Fighting in a graveyard of old broken ships, or close to the asteroid belt of a planet (so with an effect giving the feeling of a ring being seen slitghly above the trench, Big asteroids at the front of the image flying right, and small at the back of the image flying left.Might give a great feeling of deepth). Or why not a big spinning pulsar, which intermitantly sends a ray to the screen and does some damage proportionnal to their size. Or a big swirling blackhole sucking a nebula 5such as Weirld Worlds)
Could be a big starbase at the back with some ships (tiny) flying out of it, or toward it …
Well, you get the idea. It think that landscape visual effects are great additions. (I actually could even imagine a DLC with just a bunch of them… )
