Alien Storm (set 1, Japan Rev B, 2 Players, FD1094 317-0146 decrypted) [Bootleg] Overview
Alien Storm is a beat 'em up shooter that Sega unleashed on arcades back in 1990. You take control of one of three alien hunters and blast your way through hordes of insect-like extraterrestrials. This particular version is a bootleg - it's a decrypted copy of the Japan Rev B set, supporting two players. It's a revision of the original code, and since it's decrypted it runs smoothly in emulators without any fuss. The game sits in that sweet spot where run-and-gun and punch-kick beat 'em ups overlapped, typical of Sega's early 90s arcade output.
The action is straightforward: you move left and right across side-scrolling stages, shooting aliens and dodging their attacks. Coins up to play, pick a character, then fight through waves of enemies. You can jump, aim diagonally, and hurl special weapons like grenades when you grab a power-up. There are also short first-person shooting sequences where you blast bugs from a fixed perspective. The core loop is simple - clear out the bugs, survive until the boss, then move on. Arcade difficulty keeps things hectic, especially with two players working together.
What makes this bootleg worth checking out is how neatly it captures Sega's arcade energy without any region-lock or emulation quirks. It's not as deep as later entries in the genre, but the co-op action and that weird mix of side-scrolling and first-person shooting give it personality. If you enjoy games like Alien Syndrome or the run-and-gun sections of Contra, Alien Storm hits a similar note. Just keep in mind this is a bootleg - it's the exact same game, just decrypted for convenience.

How to Play Alien Storm (set 1, Japan Rev B, 2 Players, FD1094 317-0146 decrypted) [Bootleg] Online
Getting started begins with inserting a coin - press a mapped coin button (usually 5 on the keyboard) or hit Start while on the attract screen. The game shows a title screen and then a character select screen. You can choose from three hunters: each has slightly different stats but the difference is minor. Pick one with the A button (X key) or accept the default. Once in the stage, start moving right with the D-Pad and attack with S (B button). The core loop is pushing forward, blasting every alien on screen, and collecting weapon upgrades dropped by enemies. Watch your health bar - pick up energy icons to restore it. The game throws both side-scrolling and first-person segments at you; during the first-person view, you aim with the D-Pad and shoot with S. Use the jump (X) to dodge attacks or hit flying enemies. Coins are limited in emulation? Not really, but the arcade default is three credits. Just mash Start to continue if you run out. The game ends when you lose all lives, so practice the patterns.
