If you had not grabbed this one a while ago, you can do so now again, this time the deluxe edition. There is a condition though, Humble Bundle is giving away Steam keys of a survival city-building strategy game, Surviving Mars Deluxe Edition until today, Monday, June 14th 2021.

Welcome Home! The time has come to stake your claim on the Red Planet and build the first functioning human colonies on Mars! All you need are supplies, oxygen, decades of training, experience with sandstorms, and a can-do attitude to discover the purpose of those weird black cubes that appeared out of nowhere. With a bit of sprucing up, this place is going to be awesome!

The Deluxe Edition of Surviving Mars provides ambitious colonists with a variety of new ways to customize their new homes and domes. New content, exclusive to the Deluxe Edition, includes:

• The “Metropolis” Building Set: Add some chrome to your dome with a shiny new visual upgrade to your infrastructure, providing you with chromatic skins for Oxygen Tanks, Water Towers, Fuel Refineries, and more.
• Radio Station: An additional in-game radio station, with new music and chatter, comes exclusively with the Deluxe Edition.
• New Housing Styles: Three alternative skins for residential housing structures allow you to add different flair and design to your colonies.

Just head over to Humble Bundle before Monday, June 14th 2021 7 PM CET, click on the Get The Game banner to get your Steam key. Then redeem it in Steam as soon as possible. Simple as that. After that, the game is yours to keep, and play, forever.
