- TRIVIA -
Released in March 1990.

This game is based upon the movie of the same name (released in 1986).

An Aliens cabinet is seen in The Simpsons arcade game. However it's
revealed that a Xenomorph which scares off a Space Mutant (a recurring
movie franchise on the TV show) is reveals itself to be none other than
Marge Simpson inside the Alien costume.


- UPDATES -
The US version is slightly different, it has the "Winners Don't Use
Drugs" screen.

The Japanese version is very unlike any other version to appear in other
countries :
* Most obviously, both APC driving levels have been entirely deleted.
* As such, the subplot of rescuing Newt is gone. Therefore, Newt never
appears in Stage 1.

* When you take on the 'Shrinky-Dink Alien Quartet', the first one to
fully enlarge hops off-screen, leaving you to only battle the other
three.

* Many of the aliens, zombies, and mid-bosses can be killed with fewer
shots.

*Two new kinds of minor enemy appear in the game :
a) An adult alien bursts out of the background wall during the vent
portion of what we consider Stage 5. It functions much like the
Ground-Poppers and is destroyed just as easily, but with new animations
and from a different angle. It is the only one of its type in the game.

b) The small form of the Shrinky-Dink Alien, as seen in the form of the
second mid-boss in Stage 5, reappears in Stage 7. It stands alone on the
catwalks with a ring of orange energy circling it and the catwalk in a
kind of 'shield'. A few shots destroy it.

* Titles have been given to each level. They are as follows, transcribed
as they appear in the game.

Level 1 - Living Quarters
Level 2 - Factory
Level 3 - Factory2
Level 4 - Queen Alien's DEN
Level 5 - Escape Route
Level 6 - Battle Ship SULACO
* Special weapons and bombs appear much more frequently in the game,
dropping from the sky for the players to use at regular intervals.

* It is now possible to attain 1-ups in the game. If a player is still
carrying a weapon from the last special weapon power-up, the next one to
fall on-screen will contain a 1-up. It comes in the form of a red ribbon
with a bow wrapped around the word '1up'.

* In addition to the other enemies in this section, ground-popping
aliens now appear earlier, during the nest portion of what we know as
Stage 3.

* In addition to the other enemies, flying aliens now appear during the
first power loader segment, in Stage 3.

* Flying aliens are much more frequent throughout the outdoor portion of
Stage 5 and Stage 7.

* Extra exploding barrels appear throughout the game.
* Numerous aliens have changed color. Adult aliens are now purple
instead of maroon, face-huggers are now flesh-toned instead of green,
etc.

* Many of the adult aliens in the elevator sequence of Stage 3 have been
removed. They have been replaced with flying aliens that do NOT damage
the cables. This makes this sequence much easier.

* The beams from the 3-Way gun have changed color from purple to orange.
* During the final battle, the queen does NOT breathe fire/acid at you.
Instead, after flashing white, she sends out multiple images of herself
as a projectile! These are wider and therefore are easier to be hit by.

* The queen charges at you constantly even if you are in the power
loader. This makes the final battle much more difficult.
