About Mars Underground

If you like this game look up "Spooky Crew: Mask of the Mysterium" also on Steam. I have a demo out and I'm working really hard on it!

It's your first day at a new school. Every day is your first day at a new school. Every night the world ends.

Mars Underground is an apocalyptic adventure game where you relive the same day over and over. With each cycle new items can be picked up and topics unlocked.​

Take experimental prescription drugs. Talk to a toilet. Get hit by a car. Humiliate yourself repeatedly. All in the name of figuring out what on earth is going on.

  • Solve brain damaging mysteries.

  • Discover all the potential endings.

  • Find new stuff every cycle.

  • Talk, interact, annoy and generally bother the denizens of Phobos City as they try to go about their day.

  • All original, "dynamic" music soundtrack.

  • Can be fully played with either a keyboard, a controller or touch input.
    \
  • DLC & expansions

    I have really enjoyed this game. You wake up as Mars to the same day everyday, but as you live through the days you can go on side quests to discover more about the world you are in(or not in, or in within your mind). Each clue deepens the mystery. The art, music, and flow are all spectacular in this small and non-linear game. Would recommend^^.

    Игра "Mars Underground" — увлекательный симулятор выживания на Марсе с элементами стратегии. Графика качественная, атмосфера напряженная, благодаря ярко переданным опасностям планеты. Основная задача — развивать колонию, собирать ресурсы и противостоять природным катаклизмам. Управление слегка сложное для новичков, но сбалансированная система наград мотивирует к экспериментам. Минус — ограниченный сюжет и повторяющиеся задания. Подойдет фанатам жанра, ценящим глубину механики и стратегическое мышление.

    Okay, loved this game. It had an Earthbound vibe by way of Beavis and Butthead. BUT, I think that with just how cool some of the mystery was to the plot, not to mention how funny the writing was and how good and satisfying the puzzle solving was, it was disappointing that there was no satisfying overarching conclusion to the story within the game itself.
