Battle Queen. Empress.

[Whistle]

Summary (a quick, 2-3 sentence summary): Allow the xeno Queen to evolve when the evac shuttles are called.

Benefits (How this will benefit the server and game as a whole): At current the xeno's race get a burst of adrenaline once the hosts attempt to make their escape.
This gives a time limit for Xeno to rally, gather their strength, wait to evolve or attack and take as many down as they can.
This timer has on many occasions forced the xeno to stop playing smart and charge head long into the fight even if they have just received heavy losses on the marine retreat from planet.
The adrenaline can be more than just flavour text or a wee boost to the team in favour of a more battle ready queen evolution.
This will allow Queens to become more aggressive during boarding actions and give the xenos a bit more oomf out the door for when time is not on their side.

Details (Description of how you think this would work, the benefits, etc): Allows a more even playing field when assaulting with limited time, a possible entrenched position and with hardened marines who are now willing to give up a multimillion dollar ship to live.
A cornered animal is the most dangerous.

I would suggest increasing their armour or health or make them similar to crushers in their immunity to lesser explosions (no nade spamming an enclosed space to kill the big bad and scatter the enemy leadership to the wind.)
Make their execution ability faster and cost less.
Open to the idea of a counter balance that does not involve removal of egg laying as that will always be a necessary queen role, even if it fits with canon.

Implementation (Optional, if you have an idea how to implement it): Incorporate a trigger that when evac has been called, that the queen can evolve.
I am told we have a sprite from alpha stage gameplay.

Well, it will help queen not to be tier 2 alien.

Did you just fucking diss the Queen? She is easily as powerful as a Tier 3.

Did you just fucking diss the Queen? She is easily as powerful as a Tier 3.

She relies on teams, even having 1 other Xenomorph with her can tip the scales of a battle, due to her stun. However, she's too slow to use the stun by herself unless she's lucky or can table slam people, but with a team of Xenos? Those marines are good as dead. The Queen is a support class.

The queen can now become an empress through waiting a really long time.
