They should use Warrior Xenomorph instead of Drone

[Viper]

As far as I can tell, The Alien in the game is Drone.
I read the wiki said that "Drones are more calm Xenomorphs, able to plan and would rather sneak attack an enemy than run into the line of fire and face them head on."

Calm? Are you sure? and she is not sneaky too.
If I record correctly, Drone don't have the armor on it head . Normal gun fire on the head should able to kill it. But NO. You cannot kill it even with your bolt gun.

I think the one who hide in the vent should be Drone, and the one who searching around should be Warrior.
