WHAT'S THE STORY, MUTHUR?
--- The Prequel: Chariot of the Gods ---
Space truckers manning the starfreighter USCSS Montero, commissioned by the Weyland-Yutani corporation, were running the Gauntlet, trade route between Anchorpoint Station and the Frontier to deliver a special order of Helium 3 to Sutter's World.
While the trip began fairly routine and without incident, the crew quickly realized they were awakened early and severely off course. The ships computer had taken them to the location of a drifting derelict that had been missing for nearly 3 quarters of a century. It was a Science Exploration Vehicle designated USCSS Cronus.
Performing regular checks on the computer system, the technician and cargo handler discovered a hidden order to redirect the ship to this location and someone had sabotaged the cooling unit so the crew would be forced to abandon their ship and recover the Cronus along with any science data. The cooling unit was fixed before causing any lasting damage.
Under contractual obligation and the mutinous AI sytem, the Montero away team boarded the ship to discover an ill fate had befallen the science vessel and its crew. The Montero crew managed to recover science data, alien specimens and survivors, one being the twin sister of their medic (it's complicated). They bore witness to a horrific infectious pathogen, alien creatures, and mutated abominations and they sabotaged the Cronus' reactor to self-destruct.
Meanwhile, the Captain and Pilot fended off an attack from Seegson corporate privateers of the ship Sotillo.
Most of the Cronus survivors were killed by abominations or died from the mutagenic side effects of a botched vaccine created by the Cronus scientists. The Montero crew made it out alive, except for the paranoid captain, the pilot was disarmed (literally) and some of the others were injured.
As the Montero crew approaches Sutter's World, nine year old Tsuki Roku wakes from a cryosick coma under the care of her twin sister, Hikari, who was found 20 years earlier in an escape pod.
--- Sutter's World ---
The Sotillo, a privateer ship commissioned secretly by Seegson Corp, attacked the Montero during their salvage of the Cronus and fled after being defeated by the Captain and Paddy Lohan.
They arrived before the Montero to the paradise colony known as Sutter's World. Its surviving crew set down at an undesignated landing zone in a clearing of the Wombwood forest. There they delivered the stolen cargo whose contents were unknown to them. Also, unbeknownst to them, the crates were soon opened and alien threats were let loose by their contact, a corporate spy known as Ladon aka Irving Shusett.
A handful of colonists from the Crowning Point settlement are going about their everyday lives when they start to get roped into the danger.
The Montero crew arrived a few days later to the settlement. They debriefed with and bribed the local WY corp admin to be left alone. Now they are trying to settle into the colony and move on with their lives.
The Sotillo crew are all dead, some of them killed by an alien entity.
On the verge of being discovered or having a nervous breakdown, Irving Shusett has caught the Montero crew in the act of stealing a synthetic body for their lost crew member Vera. They now owe him a favor.
Two different Xenomorph threats are attacking from different areas near the colony. The Crowning Point Security Team is quickly being overwhelmed by investigations of missing persons and reports of strange fauna attacks. Marshal Glenn Roberts, a survivor from the Montero, is getting to the bottom of it..
Meanwhile, on the Montero launched into orbit around the planet, a WY science team is studying the mysterious alien specimens and data recovered from the derelict Cronus. One of their experiments has gone wrong, resulting in the death of Dr Broadsworth and the termination of an alien hybrid. Now the science team has activated a synthetic copy of the doctor who continues to work on a vaccine for the Cronus virus.
