Looking at the Hive, I'd say there was a Queen. She just wasn't part of the game. Had she been in the game, I'd have preferred a non combat role for her. Either 1 of 2 scenarios.
1. Amanda finds her way into the Queens chamber to avoid the pursuing Aliens. The room is large and dark, with a blue tint, similar to the Queens chamber from the second film. Amanda let's out some quiet dialogue, such as a "oh my God". The player is able to see the queen from about 20-30 feet away. There's some light smoke or haze in the air, and an egg can be seen being deposited on the floor near the queen. The Queen never awakens and the player is narratively forced to continue out of the chamber and back into the hive.
2. The same as above, only after a second line of dialogue or some scripted noise by Amanda, causes the Queen to awaken. After a nice animation of the Queen awakening and taking stock of the intruder, she rears her head back and screams loudly, summoning her children. The tracker is heard beeping, as Amanda sees signals closing in from all directions and realizes she needs to escape quickly. The player runs out of the chamber, using the motion tracker to guide their way to an appropriate escape, as the Queen can still be heard roaring deep within the Hive, even once Amanda is far away.
