Alien Storm (エイリアンストーム) for the Sega Mega Drive is an interpretation of the 1990 Sega System 18 game, Alien Storm.

Story

A homicidal alien race is invading Earth, and the only thing that stands between them and world domination are a special forces team known as the "Alien Busters."

Gameplay

The game is a beat-'em-up and plays virtually identically to the arcade version of Alien Storm. It mixes brawler gameplay with first-person shooting sections. Characters walk with and and move backwards and forwards in the plane with and . They roll with , which passes through enemies. They run with or , which can also pass through enemies if the player continues to hold in the direction of the run. Characters jump by pressing while running.

Characters fire their weapons with , which can be pressed repeatedly in quick succession for a chain attack. Rapid-fire can be enabled in the options before starting the game. Weapons consume a small amount of energy. When characters run out of energy, their regular attacks are replaced with weaker melee attacks. Attacking while running or dashing consumes no energy. Characters can perform an overhead attack while jumping. Each character also has a special attack that damages all enemies on screen with , but this attack consumes a large amount of energy.

For the first-person shooting sections, the targeting cursor is moved with the D-Pad and shoots. Items are collected by shooting them.

Energy can be restored by collecting items. Health restoring items are very sparse and given out randomly during first person sections.

The game supports two-player simultaneous play. This version also features two additional modes: The Duel, similar to the mode of the same name seen on Golden Axe, where the player battles nine rounds of enemies, and a versus mode where two players can face off against each other. The Duel can only be selected if there is one controller plugged in, which means it is inaccessible on emulators or official versions that are permanently set to have two controllers plugged in (including the Steam version).

History

Legacy

This version of the game was included in Mega Games 3 and Mega Games 6 Vol. 2. It was also re-released for the Wii's Virtual Console service in 2007 and 2008, and was also bundled as part of Sega Mega Drive Ultimate Collection for the PlayStation 3/Xbox 360.

Versions

Unlike other ports of the game, the Mega Drive version overhauls virtually all of the levels from the arcade game, while also changing graphical elements so that the game is more suited to the Mega Drive's hardware. Though the game plays almost identically (save for differing enemy placements and tweaks), it is shorter in length, and drops some audio tracks in favour of brand new ones presumably to fit the new levels. The changes are not as distinct as those found in other early arcade-to-Mega Drive conversions, namely ESWAT: City Under Siege or Shadow Dancer: The Secret of Shinobi, but they are significant enough for it to be classed as a different Alien Storm game. The Mega Drive version also changes some story elements, such as removing the characters working at a food truck named Alien Burgers.

The game is identical in all regions and not region-protected.
