Random soldier gets infected, kills karine chick...faris chick dies by baby neomorph...oram dies next when David acts like he's saving them...lope dude and the ricks dude die in a search mission looking for oram by regulate xeno that is birthed from oram, I can only assume they stupidly decide to spilt up at the fork in the hallway or something...then you see the xeno drop down and kill ricks in Davids lab and the other douche discovers orams body (which he does in the trailer) just as he hears the scream, run in and is killed also. Which leaves Walter who will sacrifice himself to become part of the evolution of Davids work. The xenos we see in the trailers ON planet will not be the same one on the ship at the end. They defeat the ones on the planet, think they get away, but Walters son (too soon?) More biomechanical and the traditional xeno will hunt down and kill the rest of the d bags...tennesse will die where we see him dying lol and Daniels dies also in some sappy way to create a possibility of a sequel
