Memories of Mars - open world survival game set on Mars

Memories of Mars is an open world survival game where you have to craft, build and fight for your survival. The game is set 100 years in the future among "abandoned mining operations on the red planet, as the dream of exploiting and colonizing Mars has proven impossible. You play as a recently awoken clone who learns its lifespan is limited by the lethal solar flares that hit the surface of the planet every few weeks. Tasked with surviving the barren wastelands of Mars, players must explore the unforgiving Martian terrain and build a habitable homestead while fighting against a variety of dangers including strange enemies, harsh environmental elements and other human clone survivors."

The game is developed by "Limbic Entertainment" and currently is in early access on Steam.

Here are some images and a trailer from the game:

Mars house interior and exterior

British The Sun has published an article what the human residences on Mars could look like by 2050 with architects and scientists prototyping several possible types of homes for would-be Martian colonists. All the designs are meant "to protect interplanetary homeowners from hazardous cosmic rays, space radiation and Mars' severe dust storms, as well as insulate them from the cold."

Here are interior and exterior images for the 3rd design - individual house.

Concept art from "Dome City" - cancelled VR adventure game set on Mars

"Dome City" was a space adventure video game project with multiplayer (rarely seen in adventure games) and virtual reality support. It was developed by a small indie game developer "Overon Station", relaying on a (unsuccessful) crowdfunding campaign on Kickstarter, and never left past the pre-Alpha stage. In the game three young characters would be stranded fighting for survival in a domed city on Mars abandoned for 100 years. Sad the game didn't saw its release; the concept was interesting.

Here are some concept art images and a teaser for the game project:
