6:30 Terminators, and a giant terminator
11:43 - The creature that looks like the concept art above
12:45 - Flying Xeno
13:40 - Somehwat Aliens inspired boss that spews xenos
If you've played the original there are facehuggers at the last boss that spawn from eggs. There is also what appears to be either a giant chestburster, or adult xeno inspired head in the last level.
The design aesthetic of the later levels of most of the games definitely took a lot from the hive in Aliens.
