Alloy Slinger (Metalgun Slinger) is a 2D action-platform-shooter exclusive to the Game Boy Advance. Players control Billy MacDoleane, a young bounty hunter in a wild west-meets-science-fiction world, as he discovers and upgrades a special revolver that fires powerful projectiles. Core gameplay involves side-scrolling levels where the hero runs and jumps across platforms, dodges spikes and holes, battles waves of enemies with the revolver, and occasionally rides a bike to clear the path for his friend. Upgrades expand weapon power and allow combos like slide attacks and multi-directional shots. Story follows Billy's quest to defeat the parasitic alien threat that possesses people in this futuristic Old West. Characters include Billy MacDoleane as the playable hero and Peru Nogura as a recurring main enemy boss. What stands out is its unique western sci-fi setting combined with Contra-style shooting mechanics adapted for handheld play, offering over 10 main stages plus hidden levels for a 10-15 hour experience with extensive collection elements.
