Mars Base Tycoon

Mars Base Tycoon is a sci-fi tycoon game on Roblox developed by Mystery Tycoons where players build and defend a base on Mars, pilot tanks and fighter jets, battle alien invaders, and raid rival players' settlements. Created in March 2023, it has accumulated 13.7 million visits and an extraordinary 427K favorites - a 3.1% favorites-to-visits ratio that signals genuine player affection well beyond what the visit count suggests.

The base loop starts with pressing upgrade Buttons scattered across your settlement. Each button unlocks a new facility or passive income source and expands what your base can produce. Then the combat layer kicks in:

• 🏠 Buttons - upgrade nodes that unlock base facilities and passive Cash income, from resource generators and living quarters up to the Medical Facility
• 🚗 Tanks - driveable ground vehicles used against alien waves and rival players in raids
• 🚗 Fighter Jets - pilotable aircraft for aerial combat and reconnaissance; also a separate gamepass for early access
• ⚔️ Alien defense - Golden Aliens and Robots attack in waves; defending them with vehicles is the active gameplay layer between passive tycoon upgrades
• ⚔️ Raids - with only 6 players per server, PvP attacks on rival bases are direct and high-stakes rather than abstract background events

All base progress autosaves, so players can resume at any point. Joining the Mystery Tycoons Roblox group rewards 500 free Cash on first join - worth doing even when no codes are active. Gamepasses cover vehicles, defense installations (Mega Turret, Laser Turret), automation tools (Auto Collect, 2x Cash), and quality-of-life upgrades.

For a different sci-fi tycoon format, Space Mining Tycoon focuses on resource extraction rather than combat.
