Charming Soviet-on-Mars tower defense that clicks for about six hours, then runs out of planet to conquer. Worth it at the right price, not at full.

My first instinct when booting Mars or Die! was to treat it like a compact grand-strategy puzzle, the kind you finish in an afternoon and walk away feeling clever. That instinct is mostly correct, but there are a few important asterisks. The core loop here is built around four verbs: gather, build, fight, and upgrade. You swap control between two cosmonauts on foot: Scout Bean, who is fast and carries a bullet-deflecting shield, and Major Bob, a slower bruiser with a nine-round pistol. When you are running one, the other will semi-autonomously mine crystals or patch up damaged structures, which is a tidy design that reduces the micromanagement overhead without eliminating it entirely. The building side is more interesting than the genre label suggests. Solar panels radiate power to everything placed within their radius, auto-miners extract finite crystal deposits from fixed positions, and O2 tanks keep your cosmonauts breathing since oxygen doubles as health, sprint fuel, and revive currency all at once. That triple-duty oxygen mechanic is the game's genuinely clever moment: venting your suit to dash costs the same resource that absorbs enemy hits, so every decision to sprint across an unsecured map tile carries real cost. Defensively, you are arranging turrets, heavy turrets, stun turrets, mortar launchers, and barricades into kill corridors, then watching Martian eye-blobs of various sizes test your geometry. A post-launch update added the mortar turret for AoE swarm clearance and stun turrets for crowd control, plus a per-structure upgrade system scaling individual cannons up to level ten, which added some welcome build variety. Where the game falls short is exactly where strategy fans will feel it most: content depth and AI quality. The campaign runs two sets of nine missions with objectives split between defend, escape, and seek-and-recover modes, but the mission design repeats its own tricks quickly. Once you have solved the solar-panel grid once, later levels simply throw more enemies at the same formula rather than introducing new constraints. The enemy AI and the partner AI both suffer from pathfinding issues, getting wedged in terrain corners in ways that trivialise endless mode rather than stress-test your defenses. Community feedback on Steam, which sits at a mixed 41 percent positive from 31 reviews, echoes the same concern: the roguelite label on the store page oversells what is really a light mission-reset structure, not a run-based progression system. Total playtime before the campaign exhausts its ideas lands somewhere between six and nine hours, with endless mode extending that modestly if the pathfinding bugs do not break the tension first. For the audience: if you enjoy compact tower-defense games with a dual-character twist and can appreciate a satirical bobblehead aesthetic mocking imperialist futility, there is a genuinely fun few sessions here. The controller support is solid, the voice acting from your increasingly unhinged Supreme Leader is worth a laugh, and the oxygen-as-everything mechanic keeps early missions tense. Strategy veterans looking for long-term decision trees, mod support, or meaningful late-game scaling will find the cupboard bare fast. Approach it as a palate cleanser between heavier titles, not a destination. Diego, Scout Team
