So awhile back I made a series of posts explaining potential story based DLC and how they could work, I think I was spot on with one of them but before I get onto that I'll leave the link to the Twitter post showing a brief glimpse of what's to come:

Now hopefully you watched it because I'm going to talk about my post idea and how I think its leading into a Ultramorph appearance as well as Neomorphs, I feel like everyone is aquantied with the Neomorph but for people who dont know what a Ultramorph is it's a extremely powerful Alien spawned from a Engineer
They have been shown throughout comics to be extremely powerful typically being depicted as more dangerous than a Queen and from what we are shown the evidence matches up
The Shadow on the wall appears massive and accompanied by the loud footsteps lead me to believe its something gigantic and the Ultramorph fits that description
The teaser also shows dead Xenomorphs and wouldn't you know it but the Ultramorph is also known to be hostile to other Aliens as in one of its comic appearances it destroyed a Hive.
To put the final nail in the coffin the teaser is heavily focused on the Ancient Ruins, the same ruins where the Engineers supposedly resided.
So seems like it's most definitely a Ultramorph which if it is I cannot wait for it, it's always been a badass and powerful alien and it's great to see it get a updated modern rendition.
Also as for the Neomorph you can see it if you look close enough to the background
