Demon Front (VM103XX, S103XX)

Released in 2002 by Taiwanese game developer International Games System (IGS) for arcade platforms, Demon Front (often identified by its firmware codes VM103XX and S103XX) is a fast-paced side-scrolling run-and-gun shooter that quickly earned a cult following among retro arcade enthusiasts for its polished gameplay, vibrant pixel art, and unique twist on the genre’s standard formula. Often favorably compared to the beloved Metal Slug series, Demon Front sets itself apart with its core companion pet mechanic, which lets each of the four playable characters summon a loyal magical creature to fight alongside them. The game’s plot follows a group of mercenaries tasked with infiltrating a demon-controlled island to stop an evil warlord from opening a portal to the underworld that would unleash apocalyptic destruction on the human realm. Each playable character comes with distinct base weapons, special attacks, and unique pet abilities: Jake, the default male lead, wields a heavy machine gun

Game Guide

Start your Demon Front run by picking a character that matches your playstyle to maximize your chances of success. If you prefer high, consistent damage output and straightforward combat, go with Jake: his base machine gun has reliable range and rate of fire, and his fire dragon pet deals heavy area damage to groups of enemies and boss weak points. If you struggle with crowd control, Sara is your best bet: her spread shotgun hits multiple targets at close to medium range, and her frost fairy pet can freeze enemies solid for 2 to 3 seconds, letting you take out tough foes without taking damage. For players who prefer long-range attacks to avoid close combat, Dr. J’s laser rifle pierces through multiple enemies and obstacles, and his electric spirit pet can chain lightning between 5 or more enemies at once. Golem is ideal for players who want extra defensive utility and fast boss takedowns: his rocket launcher deals massive single-target damage, and his stone golem pet can block incoming projectile attacks for up to 5 seconds when activated. Master the pet charge mechanic next: holding down the pet summon button for 2 full seconds charges a special super attack for your companion, which deals 3x more damage than a standard pet summon and covers a much wider area. Save these charged pet attacks for boss fights and crowded stage sections where you are surrounded by 10 or more enemies, as they can clear the screen in seconds and prevent unnecessary damage. Always prioritize picking up weapon upgrades when you see them: each upgrade increases your base firepower by 50% for 30 seconds, and stacking 2 upgrades lets you deal double damage until you take a hit. Destroy every destructible object you encounter, from crates to stone pillars: many hide hidden health pickups, extra lives, or 1-up tokens that can extend your run significantly. When fighting bosses, focus exclusively on their glowing weak points first, as these take 4x more damage than other parts of their body. All
