They sort of included that when it was running around onboard the Covenant before being locked inside the terraforming bay.
Nothing like the trailer shot though.
Funny thing is, some of the people from Fox I spoke to after the press showing I went to on the 2nd were surprised when I told them it wasn't in, because it had been when they'd seen the film. Evidently it was cut quite late in the day.
Thats my favourite shot of an Alien in any film. Loved how it stood. It even made my eye brows raise.
That shot was about the only thing from that entire sequence that didn't disappoint.
