I have also been keeping track of additional rules Andrea has been posting on FB here:

Clinging N, 1XP per level, up to 3XP
Clinging is the ability to move up on walls and ceilings using Crawl, Walk, and Run actions. Sprinting is not possible. The trait comes in three levels to represent different grades of freedom while clinging, depending on the means used by the creature to stick to walls. Details on how the character does it are left to the player's common sense.
With the first level, all limbs are used to stick to the wall.
With the second level, the character can have one free limb while clinging, and use it to hold equipment or use a tool/weapon (but reloading is going to be impossible).
With the third level, the character can have two free limbs while clinging, but may still not use Long or Two-handed melee weapons.
While clinging, a character gains an elevation +1 bonus to attack in melee any non-clinging
If hit while Clinging, any result of a crippled limb or knocked Prone means the character falls.

Acid Blood 4XP (N)

The character belongs to an alien race whose bodily fluids are aggressive acids. Every time the model takes a wound, any character in base-to-base contact with the alien must perform a TN15 agility roll (add levels in Agile, subtract -1 if character is carrying a Heavy load or is Big or Huge) or take a Damage 2 attack in a random location. If the unmodified Endure roll is a 5 or lower, the acid eats through the character's clothes or armor, and the character must spend one action to get rid of the armor/clothing in the affected body part or suffer an additional Damage 2 attack each time the initiative switches. Multiple sprays on the character have each their potential Damage roll.

Please let me know if you try out an Aliens versus Marines scenario. My feeling is, RS is not very well suited to that. I think it is mostly focused on RPG-like scenarios. Just like how the D&D rulebook is mostly rules about combat but playing D&D isn't or at least doesn't have to be all about combat, I think RS is probably at its best when combat is secondary to narrative goals. By contrast, I think an Aliens versus Marines miniatures game really needs to be about getting the iconic feel of that combat right.
