For my game I was going with the idea of many different sects and groups. Humans had marines, intersellar trading companies, pirates. Aliens had Giger/CamerAlien, Predator born, gene mutated, K-species, red Aliens. Predators were clan hunters and solo hunters.
I really hope we get some layer of customization for this one. I'd love the ability to upload my own costumes and Predator armor. Help with player immersion.
