About Alien Storm
Alien Storm is a side-scrolling beat 'em up. The game resembles Golden Axe, with a similar artistic style, three playable characters (a man, a woman, and a novelty character) and pick-up or power-up special attacks. The player (one player only on the Master System version, up to two players on the Mega Drive version, three on the arcade version) selects from the three different characters to embark upon a quest to save the Earth from an alien invasion. All of the Busters are playable from the beginning of the game. There are 6 missions to complete (8 in the Mega Drive version) with several stages, and each mission has the player blasting aliens, from the streets to the mother ship, where the mother of all aliens can be found. This task becomes increasingly difficult with each new mission, and the aliens are capable of hiding inside objects such as plants, postboxes, trashcans, drums, and other items. Each mission has an objective such as rescuing people or destroying an UFO. When dealing with a few aliens, flying heads will appear, which can be shot to collect life or energy. Energy is used specifically to power the energy based attacks of the player's weapon (such as flames or electricity) and to use the much more powerful special weapons. In a similar format as other early Sega arcade games, each character has unlimited usage of various short-range attacks, i.e. punches, kicks. Along with these standard attacks, each character has their own individual weapon (Garth's weapon that shoots lightning is replaced with a flame weapon in the Master System version). Special attacks are also included, and vary depending on the character chosen at the start of the game. For instance, Garth summons an U.S. Air Force starship that drops bombs across the street (in the Master System version he has Karen's special, a ballistic missile strike). Scooter will teleport out of his present location and leave a series of bombs that will blow up on the appearance of aliens, after which he will re-appear (in the Mega Drive version he just explodes, leaving his head, which his new body returns to retrieve). Karen calls down a nuclear missile, which incinerates every foe on the screen. However, a large amount of energy is depleted by using each character's special attack, and cannot be used if the energy of the player's character is too low. There are few bosses in the game. The arcade original only features a single boss that has three distinct forms. The Mega Drive port has two of these forms as two separate bosses. At the end of each mission, the side-scrolling gameplay shifts to either a shooting gallery perspective where the player must take out the aliens that pop out of various locations, similar to the bonus stages of Shinobi and Shadow Dancer, both also by Sega, or a running section that is similar to the side scrolling mode but plays like a horizontal shooter instead with projectile weapons.

Prices are per version and are not interchangeable, and neither are the reviews: conversions in this era were often built by a different studio than the original, so a score earned on one machine says nothing about how another plays.

The Sega Master System version
A cut-down home version of Sega's arcade brawler, with one player and a changed cast, and an inexpensive European cart.
Alien Storm began as a Sega arcade game, and this is the Master System version, developed by SIMS and released by Sega in Europe in December 1991. Alien Busters fight an alien invasion, each with a personal weapon.
The Master System game is one-player only, where the arcade game takes three. The team loses Karen, the robot Scooter is renamed Slammer, and Garth's lightning weapon is replaced with a flame weapon.

“Quite simply, Alien Storm is very unsuccessful conversion that fails to deliver any of the thrills and spills of the original coin-op.”
“* Imply doasn't make ll a great game. Graphically it's as good as you could expect and sound la OK, but Allen SlOrm simply isn't the type ot game you want to keep coming beck to.”
“Graphically, Alien Storm’s pretty average. Sprites are clearly defined and colourful, but overall it’s on the bland side. … Nevertheless, Alien Storm’s an enjoyable, polished game.”
“the graphics are the best thing about the game are the graphics - and they're crap. Avoid this one”

Before you buy
The European cart is the one to look for, so there is nothing to choose between regions. Loose, it sits below the middle of the European-only carts, and the look-alike risk is low. Check the manual is included in a complete copy.

The Sega Genesis version
A good-looking Genesis conversion of Sega's alien-blasting arcade game that is easy to finish, and a fair buy in every region.
This is the Genesis version of Alien Storm, developed and published by Sega. It came out in Japan on 28 June 1991, with North America following in July 1991 and Europe later in 1991. You pick one of three Alien Busters and fight through eight missions, from city streets up to the alien mother ship, and the Genesis game allows two players at once.
Mean Machines Sega called it an outstanding conversion of the coin-op, with great graphics and highly enjoyable one- or two-player action. Its one big complaint was that the game is too easy, and it warned experts that they might finish it prematurely. The Genesis port splits the arcade game's three-form final boss into three separate bosses.

“An absolutely outstanding conversion of the coin-op, with great graphics and i enjoyable one or two-layer action. The big problem is that it's just too easy.”
“This horizontal alien shoot-em-up is just far too easy. The two-player option is fun and the graphics look pretty good, but illl all be over too soon.”

How the Sega Genesis version differs

Among US carts it sits above the middle. The European cart usually costs noticeably less than the US one, while the Japanese Mega Drive cart usually costs a little more and has a different cartridge shape. A complete US copy means the case, cartridge and manual.
