Acidic Blood: Xenomorphs have a special defence: acidic blood. This biological acid is intensely powerful and will spray from any physical wound the xenomorph takes, actively corrosive for 1D6+2 combat rounds. Any target 1 meter from the xenomorph must make a DEX x5 roll to avoid being spattered. Failure indicates that the character takes 1D3 points from the acid. Armour will initially protect against this acid, but not for long. It will continue to eat away at armour protection, doing damage each combat round until it is through the armour. The GM should keep track of the acid’s damage each round until the armour’s value is overcome. At this point, it will begin to burn the character. Removing the armour without being burned takes one full combat round and a Difficult Agility roll. If using the optional hit location system, only the armour on the affected hit location(s) need be removed. Failure indicates that the armour is still on. A fumble indicates that the acid got onto the character. Once a character is being burnt by the acid, it will continue until it is neutralized by some force, or the acid eventually stops being corrosive at the end of the 1D6+2 duration.
Wall Walking: Aliens can walk on walls and ceilings, whether on all fours or standing upright. They can stand still on vertical or upside-down surfaces as if on the ground.
Immunities: Aliens are effectively immune to damage from acid, cold, radiation, vacuum, and inhaled gasses. They take half damage from electricity.
Aliens, or xenomorphs, (Internecivus raptus) are a deadly extraterrestrial species with complex life cycle, and a need for a host organism in order to reproduce. When standing upright, the Aliens are vaguely bipedal in form, though they adopt a more hunched, quadrupedal stance when walking or sprinting. They have a skeletal, biomechanical appearance and are usually coloured in muted shades of black, blue or bronze. Aliens do not radiate heat, as their body heat matches the ambient temperature of the environment in which they are found. Aliens have the ability of running and crawling along ceilings and walls. They have great physical strength, having been shown to be capable of breaking through welded steel doors.
Aliens have segmented, barb or blade-tipped tails. The tails have a flat ridge of spines at the base of the blade, to help them swim. They are also adept at using their tails as blunt weapons, sometimes to deadly effect.
They have elongated, cylindrical skulls, but possess no visible eyes. How the creatures see is uncertain. A fisheye lens was used to illustrate the Alien's point of view. The aliens' mouths have a second inner set of jaws, which are located at the tip of a long, tongue-like proboscis. The Aliens' inner jaws are powerful enough to smash through bone and metal. They eat with their "tongue mouths", not their outer mouths.
Human-spawned Aliens have between three and six fingers. Aliens have been alternately portrayed as both plantigrade and digitigrade organisms.
Alien “blood” is an extremely potent acid and is capable of corroding on contact almost any substance with alarming speed. It is dull yellowish-green in colour, and seems to be pressurized inside the body so that it spurts out when punctured. Some suggests that the acid is not blood, but a fluid maintained under pressure between a double layer of skin. The Aliens are conscious of the effects of their acidic blood, and even use it to their advantage, two Aliens escaped a cage by killing a fellow Alien so that its acid ate through the cage floor. It is theorized that the Aliens' acid blood could be some type of "hydrosulphuric acid" composition due to its corrosiveness and the conspicuously toxic effects on living human tissue.
Aliens can produce a thick, strong resin (secreted from their maws, giving them the look of a slavering beast) that they use to build their hives and to cocoon their victims, and they can use the walls of their hives as camouflage.
Xenomorphs appear to possess an intelligence roughly similar to that of a typical primate. The species excels at observational learning and problem solving. Aliens have managed to learn how to operate the machinery of mechanized environments at a very basic level. Aliens were able to cut the power from a section of a habitation complex to allow themselves access to the humans inside. A queen was able to learn how to operate an elevator simply by observing it once. Aliens have demonstrated little actual emotion, save for self preservation, and maternal instincts toward their eggs.
Their life cycle comprises several distinct stages: they begin their lives as an egg. The eggs are large, ellipsoidal leathery objects between two to three feet high with a four-lobed opening at the top. As a potential host approaches, the egg's lobes unfold like flower petals, and the parasitic facehugger extracts itself from the egg and attaches itself to the potential host.
The facehugger, a form with 8 long legs and a long tail, attaches itself to the victims face, in order to implant an embryonic chestburster down the host's throat, a process which takes several hours. Removal of the facehugger generally proves fatal, as it will respond by tightening its grip on the hosts throat, and its acidic blood prevents it from being safely cut away. Once the Alien embryo is safely implanted, the facehugger detaches and dies.
Shortly after implantation, the facehugger dies, and the embryo's host wakes up showing no considerable outward negative symptoms. Symptoms build acutely after detachment of the facehugger, the most common being sore throat, slight nausea, increased congestion and moderate to extreme hunger. Over the course of between several and 24 hours (and sometimes up to a week, in the case of some queens) the embryo develops into a chestburster, at which point it emerges, violently ripping open the chest of the host, killing it. The chestburster then matures to an adult phase within a day, if it ingests sufficient energy, moulting as it grows.
Aliens are laid by an large queen alien. A lone alien warrior can also produce eggs by encasing the still-living bodies of its victims in resin, and converting them into an egg.
Alien queens are produced by special, larger facehuggers. However, some have suggested an ordinary warrior alien can transform into a queen if necessary.
