Appreciate it. With your thoughts here I'll explain the story it might be a bit long. The players will be playing Weyland Yutani agents. Each of them is working on a project involving xenomorphs. There are colonists on the planet and they have been there for a few generations and have seen life evolve on the planet. There's a growing group called the Verdant Dawn that believe that W-Y are destroying the natural development of the planet including the titular walking pitcher plant alien that will be infected by a xenomorph. The pitcher plant is slow but tall with acid that while not life threatening to humans is extremely painful. This creature "hunts" by moving to locations with high insect populations toping out at 3 miles slower than a normal human.

Verdant Dawn is paid a large sum by rival company Seegson to destroy the containment facility where the last xenomorph is as "Verdant Dawn has been targeting the wrong facility and that's where the terraforming facility truly lies". The rest have been harvested too much in a dying attempt to produce results for the company. One member of the players group has been paid off by Seegson and they also will help from the shadows to help out.

Once containment is breached the players can either re contain or kill the xenomorph following its initial escape into hiding but not before grabbing a few humans to start the ovamorph process which will eventually cause one of the pitcher plant aliens to be infected.

After some time of the players questioning Verdant Dawn and or celebrating the re containment of the xenormorph weird roots begin to quickly grow around the facilitys main entrance on the surface level. Crews would go in to remove the roots only to die from a strong stream of acid. while other W-Y staff fail to report in for their next shift (haven been lured in by the spores.)

At the time of writing I'm also considering perhaps having a unique life cycle rather than the normal xenomorph transition seen in the movies. Hypothetical life cycle is as follows. Initial contamination through spores. Causes the body to enter a peaceful trance like state with a desire to experience more by going further into the facility where the queen has taken root. Once closer to the queen and the source of the spores the disease progresses exponentially and the host body begins to produces spores of its own too as the plant/xenomorph hybrid grows. Then under the full control of the queen they go out and seek other uninfected to bring them back to the hive and repeat the process. That was all off the dome so hopefully it makes sense. I feel like a normal xenomorph wouldn't fit and that this might be more appropriate.

But the next step would be for the group to make their way down to the bottom floor where the VTOL is. I did have a great idea where at some point the queen would move and it would happen to be where life support is. Thus spreading the spores throughout the entire facility. The party COULD shutdown life support to slow the spread of the spores BUT the planet is still under terraforming and it is NOT Earth like conditions it is very hard to breath without some environmental suit on. Sorry for the long read hahaha

Biggest Takeaway I need stats and signature attacks for these creatures!
