Alien Storm (set 2, US, 3 Players, FD1094 317-0147)

Released in 1990 by Sega for arcades, Alien Storm (set 2, US, 3 Players, FD1094 317-0147) is a rare regional variant of the beloved hybrid beat 'em up and run-and-gun shooter. This specific US set 2 version uses the FD1094 317-0147 security chip for copy protection, and stands out from other regional releases by supporting up to three simultaneous players, a feature omitted from many 1 and 2-player only variants of the game. Set in a near-future Earth overrun by hostile shape-shifting alien invaders, players choose from three unique playable characters: Garth, a heavy weapons specialist with high health and strong ranged attacks; Karen, a fast martial artist with quick crowd-control combos; and Scooter, a combat robot with a high-capacity special attack gauge. The game blends multiple gameplay styles to keep sessions dynamic: side-scrolling brawler segments where you fight off slime aliens, infected human hosts, and mid-bosses on city streets, first-person shooting gallery levels where

Game Guide

Mastering Alien Storm (set 2, US, 3 Players, FD1094 317-0147) is easy to learn but hard to perfect, with these tailored tips for both solo and co-op play. First, pick the right character for your playstyle: if you are playing solo, choose Garth, as his high base health and high-damage rocket launcher projectile let you handle swarms and bosses alone without relying on teammates. If you are playing in co-op, assign roles: have one player pick Karen for fast crowd control of ground enemies, one pick Garth for heavy damage to bosses and flying targets, and one pick Scooter, whose unique self-destruct special attack can clear an entire screen of enemies when your team is overwhelmed, even if it costs a small portion of his health. During side-scrolling brawler segments, always prioritize taking out floating alien spawn pods first: these pods continuously spawn small slime aliens that chip away at your health if left unattended, and eliminating them first cuts down on enemy numbers drastically. Save your individual character special attacks for mid-boss encounters or when you are surrounded by 5 or more enemies, never waste them on single regular foes. For first-person shooting gallery levels, focus your fire on the glowing weak points on large alien enemies first, as this takes them out in one or two shots instead of wasting ammo on their armored bodies. Always pick up extra ammo drops in these segments, as running out of ammo forces you to use slow melee attacks that leave you vulnerable to incoming enemy fire. During run-and-gun escape sequences, never stop moving: jump over rolling acid pools and shoot alien pods before they open to release enemies, as stopping to fight will make you fall victim to the environmental damage chasing you. When fighting the final Alien Queen boss, assign one player exclusively to take out the small minion aliens she spawns every 10 seconds, while the other two players aim for her open mouth (her only weak point) when she leans forward to
