Mars 2120 is a 2.5D metroidvania set in the 22nd century at humanity's first colony on Mars. You play as Sergeant Anna "Thirteen" Charlotte, investigating a research facility that has become far more dangerous than expected. The colony holds dark secrets, and your mission is to uncover what went wrong while surviving the hostile environment.

The core gameplay loop centers on exploration and combat. You navigate interconnected areas of the Martian colony, discovering new biomes and uncovering secrets. As you progress, you unlock equipment upgrades and special abilities that grant access to previously unreachable areas—a hallmark of the metroidvania genre. The map becomes your primary tool for navigation and planning your route through the facility.

Combat emphasizes fast-paced action with a blend of melee and ranged attacks. You can chain together combos by mixing different weapon types and elemental abilities tied to ice, fire, and electricity. Boss encounters require strategy: you must identify enemy weaknesses, adapt your approach, and execute precise timing. The game includes various accessibility options, allowing you to customize difficulty, game speed, and visual settings to match your playstyle.

What sets Mars 2120 apart is its 2.5D perspective combined with traditional metroidvania progression. Rather than a purely 2D side-scroller, the game uses depth layering to create visual variety while maintaining the exploration-focused design. The elemental power system adds tactical depth—different enemies and environmental puzzles respond to specific elements, encouraging experimentation.

Mars 2120 appeals to fans of classic metroidvanias like Super Metroid and Castlevania: Symphony of the Night who want a modern take on the formula. The game respects player agency through non-linear exploration and rewards curiosity with hidden upgrades and alternate routes. It's designed for players who enjoy methodical exploration, skill-based combat, and the satisfaction of unlocking new abilities that open up previously inaccessible areas.
