Another piece of concept art from the game. If I had to guess, I’d say these were Imperial forces because of the uniforms, but they could be Rebel soldiers as well. The red-tinged background leads one to think that they are on Cloud City. Another clue here is the tiny alien among the squad. Cloud City was a notoriously diverse locale under the nondiscriminatory rule of Lando, so it would make sense that alien creatures are just as ubiquitous as humans.
