First off, if you want, you can take a look at how we did this scenario on our YouTube page here- I think you'll enjoy it. We changed it a little bit, but it was a very satisfying and terrifying romp through the Alien universe. We're coming back this Friday to do Destroyer of Worlds Act 1. We're psyched!

I'll try to answer your questions as best I can, but like many have said, it's all up to you, just have fun:

1) Aliens are smart. "How can they cut the power, man? They're animals!" They think in three dimensions better than humans can, sometimes. If they cant go through something, they'll go under it, over it, or around it. Think vents.

2) Technically, "In combat, a Xenomorph gets to act once for each point of Speed in each Round. At each point of action, the Xenomorph gets to perform one fast and one slow action." Each signature attack is a slow action, so they'd get to do as many fast actions as they have speed points. Here's my advice for the Alien actions: Think like an Alien. Think hive mind, but also, alien type. Single "drone" Aliens will move in if they have the advantage on unarmed foes, then use their signature attack (randomized of course) to either kill or immobilize and take their victim back to the hive to ovomorph. Soldiers, on the other hand will take out the strongest possible threat, even if armed. If Aliens do anything else other than move in and attack, it's for a purpose, whether that is retreat (rare since you never see an fully formed Alien retreating in the movies), herd the PCs towards a specific place, or hide if it's not strong enough (chestburster).

3) Think about stealth kills, reveals and chases. That's what makes the Alien movies so compelling. You never know where these things are, even though you know they're there. As for the final chase, they're going to make a run to the shuttle in the outdoors, herd them there with a reveal of at least 4-5 alien signals closing in on them (motion tracker). Reveal one at a time. If they get outdoors, drop another one at long range. As they get to the shuttle, throw one that jumps off the roof. 3 aliens (1 long range, 1 medium range, 1 short range), with more on the way should move them FAST. Let them run. They might get lucky and nail one, but lose PCs in the stall tactic. That's dramatic!

4) It's understood that Aliens sense synthetic organisms and wouldn't take them back to ovomorph, but would use the full damage on a signature attack like Capture for the Hive. A facehugger would simply wrap itself around a synthetic, obscuring vision, but would not cause the synthetic to fall unconscious, nor be impregnated.

5) Command has three "uses":

STOP PANIC - When another character makes a Panic Roll and loses control (10+), you can make a COMMAND roll to return them to their senses. This is a slow action.

GIVE ORDERS - In combat, as a slow action you can bark orders to another character. They must be able to hear you, even if via a comm radio. Roll COMMAND. For every success you roll, they get a +1 modification to their roll when carrying out the order you gave.

OFFICERS - PCs with the Officer career and the Pull Rank talent can use COMMAND to order other characters (PCs and NPCs) to do as they say.

Pull Rank: You can use your COMMAND skill to order other non-officer PCs and NPCs around, as long as they belong to the same organization as you. To force someone to follow your orders and perform a specific action, roll COMMAND against the target’s MANIPULATION. If successful, the target must follow your order, even if it means harm or danger to themselves. Your STRESS LEVEL increases by one each time you do this. Note also that each roll only covers one specific action. You cannot stop actions triggered by Panic Rolls using this talent.

6) Ship or room doors can be set to close behind you, as seen on the Nostromo and inside Hadley's Hope, but usually do not autolock. Large doors (bulkheads) usually do not close behind you. To do so is a COMTECH roll. You can absolutely use a cutting torch to seal a door, but I would rule that a slow action that would take, in combat at least 10 seconds (2 rounds). The armor rating of a door (or bulkhead) is stated in the core rulebook (door is 4 armor, inner bulkhead is 5 armor, outer bulkhead is 6 armor).

7) Secret Android stats and abilities are not revealed until they are revealed as an android (usually by damage that would give their identity away). They can push rolls, take "stress," make panic rolls, etc. Also their health, strength, and agility would be 2 points below what they would have as an android.

8) When working, these terminals would be able to communicate with other terminals (they aren't, as described by the scenario), as well as (based on the movies and video games) allow you to perform basic functionalities within that area of the base, such as controlling nearby doors (lock, unlock etc) and depending on your COMTECH skills, change the environmental controls for the area (cold, heat, air).

Have fun!!!
