Metal Slug Infinity

Metal Slug Infinity Transforms a Classic Franchise into a Strategic Idle RPG

Metal Slug Infinity redefines the iconic run-and-gun series as a fully automated idle RPG, where strategic team building and resource management replace direct control. This adaptation leverages the vast character roster and vehicular mayhem of the SNK franchise, converting it into a progression system centered on incremental upgrades and passive advancement. The core loop involves assembling a squad from dozens of familiar heroes, deploying them into auto-battles, and continuously reinvesting earned currency to break through progressively challenging stages.

Core Mechanics and Progression Systems

The gameplay is structured around short, automated combat stages where your assembled team of characters, such as Marco, Fio, Eri, and Tarma, engages enemies without manual input. Victory at each stage grants coins, the primary currency for permanently upgrading character attack power and health stats. A key strategic layer is the prestige system, activated after completing multiple stages, which allows you to reset your progression in exchange for a substantial monetary bonus, facilitating faster advancement and enabling investment into newly unlocked units. The environment shifts visually every ten levels, providing fresh backdrops for the continuous combat. An integrated turbo function is available to multiply the game's speed, significantly accelerating farming and progress for players seeking a more rapid pace.
