LIAISON's liasons

What is better than having that one crew-member no one trust aboard?
An entire team of them!

If a liaison is rich enough, he can of course hire liaisons for him.
Lawyers, accountants, technological counselors, marketing specialists, secretaries...

List goes on, for an entire squad of xenomorph food to disembark on every deployment.

Marine Recruit

An official newbie marine, that is it.
Still on training, assigned to the shooting range and not to be initially deployed.

Also with all in-game excuses to behave erratically, do weird stuff, get arrested for vandalism, razed and lynched by veteran marines and - of course - assigned for xenomorph breeding research.

B.A.L.D.I.E

The Bionic Assault and Labor Disposable Impavid Element.
Basically cheap toaster brained refurbished combat synths USCM got from black market when W-Y wasn't looking.

They don't talk or hear properly, tend to barely imitate human behavior, sometimes deploy on pajamas while wielding random junk and cause all sorts of bad human-machine interactions.

But hey? You get what you paid for.

Cat

Yes. A cat. If there is a cat aboard it should be a player role huh?

Imagine Jones walking around, purring and acting like first aliens movie's cat?

And scratching random marines into pain-crit?

We need it!

Chaplain

If there's a chapel, there is a chaplain.

Thoroughly trained on blessing marines and sprinkling holy water on xenomorphs, predators, zombies, evil synths, liaison and all sorts of evil entities.

What a buff!

Xenomorph-Predator-Synth-Zombie-SCP

What if W-Y decided to mix xenomorph and yautja DNA, augmented the result with synthetic parts, the resultant being wrecked the entire lab, got contaminated with zombifying virus, found some predator gear and manage to befriend some nasty SCPs?

That is it.

Pure concentrated overpower gamebreaking evilness.

The epic ultimate challenge for all sides to fight against.

Cooks

If there is a kitchen, there must be a cook.
And why not cooks? An entire squad of kitchen assigned crew-members?

With a squad leader, speciallist and everything?

Baked xenomorph egg, anyone? What about the deep fried facehugger?

Lab Chimpanzees

Not those fluffy, goodie, well behaving cartoon monkeys. But chimpanzees instead.

Who are five times stronger than human beings.

And sometimes do mischievous things or behave aggressively.

YEP!

Low Command

Since there is a High Command, there must be a Low Command.

A small room by space, with faxes, radios, photocopiers, some remote control overriding machines, special supply resources and even space-to-space heavy weaponry strong enough to turn any ship into swiss cheese.

Staffed with intermediary command staff between High Command and Ship Command.

Nothing can go wrong, right?
