Tristan has share some of his work on the cover variants he’s been tasked to do for the new Aliens: Defiance and Alien: Isolation cross over sequel.

We can see that its the domed Xenomorph in the background of this cover and Amanda in a spacesuit. 

Some people have speculated that the grass in this commissioned piece looks so similar to the grass in which Zula and Amanda are crouching. I am not sure if the girls could or would end up on Planet 4, but it is an interesting scenario.
